In order to meet the need for more experimental content for students with strong active learning ability and to solve the problem of students’ different needs for experimental content and depth, a teaching method of adding selective experiments is proposed in this study on the basis of basic experiments. The method is also aimed at achieving the need for multi-level teaching. In the experimental course, the teacher arranges all the students in the class and makes them perform the basic circuit experiment. The teacher then adds the selective experiments on the basis of the basic experimental circuit so that the students can freely select the experiment they want to complete and meet the need for expanding the experimental needs of students with strong active learning ability. In this study, the voltage regulating circuit experiment is taken as an example to carry out practical teaching. The basic experimental content is a single-phase voltage regulating circuit experiment, and the selective experiment is a three-phase voltage regulating circuit experiment. The final examination scores of the students who have performed the selective experiments are higher than the average score of the class, which shows that the students who have performed the selective experiments are good students with a strong need for active learning. The curriculum of this study meets their need for active learning. With the help of the realisation rate of the circuit function, the correct answer rate of thinking questions and the experimental time of students who have performed the selective experiments, it is shown that the method of multi-level teaching and differentiated experimental teaching is feasible. Through the questionnaire survey of students, it can be seen that the teaching method proposed in this study can meet the students’ need for active learning, improve students’ interest in the course, and increase the opportunities for training students’ practical ability.

In this paper, the control strategies and their characteristics when applied to the doubly-fed variable-speed pumped storage unit in generating mode and pump mode are discussed. The composition of doubly fed variable-speed pumped storage unit is introduced, and the mathematical model of every component is proposed. Two control strategies of the unit are introduced. One is the power priority control strategy and the other is the speed priority control strategy. Then, the control block diagrams of the two control strategies in the generating mode and the pump mode are established, and the parameters of the unit in each control strategy are designed. The two control strategies are simulated in power generation and pumping conditions. Finally, the conclusion that power priority strategy has a better effect on power control is obtained.

In order to solve the problem of lacking active learning and independent problem‐solving ability in the verification experiment, an experimental teaching method of designing experiment from the perspective of the teacher is proposed, in which the roles of students and teachers are changed. Students are made familiar with the platform through a verification experiment in which the teacher gives the experiment guidebook and provides guidance. Then, the target of another experiment is given. The students design the experiment from the perspective of the teacher, and write the experiment guidebook, including the experimental objectives, the experimental contents and the implementation methods. Then the students do the experiment. The power electronics experiment course is taken as an example to introduce the proposed method. The Sinusoidal Pulse Width Modulation (SPWM) inverter circuit experiment is taken as the verification experiment. After the students are familiar with the platform functions, they design a DC motor speed regulation experiment with a full bridge DC‐DC circuit, write a guidebook, and complete the experiment according to the steps in the guide book. Finally, according to the success rate and the correct rate of the results, most students can complete the design experiment from the perspective of the teacher, and the answers to the thinking questions are basically correct. According to the questionnaire survey, the method proposed improves the students' ability of autonomous learning and problem‐solving with good results.

To make students understand the working principle of circuits in the course of Experiment of Power Electronics more deeply, the author introduces a small‐problem‐based teaching method to help students master the relevant curriculum content and enhance their ability of independent problem‐solving within 1 or 2 days for balancing the contradiction between course time and burden. Teachers present some small questions according to the basic principles of circuits, and students analyse the problems theoretically. Then students get the answers and verify the conclusions through simulations and laboratory experiments. Furthermore, for comparison of the source harmonic current and the maximum line current for three types of three‐phase ac voltage‐regulating circuits with different connection modes―the three‐phase four‐wire star connection mode, the three‐phase three‐wire star connection mode and the branch‐controlled triangle connection mode―are used as an example to explain the proposed teaching method. Through theoretical analysis, simulation and experimental verification of students, three kinds of circuits are compared, and the conclusions are drawn. Based on the analysis of students’ problem‐solving process and results, it can be seen that most students can complete and get correct conclusions independently. The proposed method can improve the students’ problem‐solving ability.

In the view of the high complexity and a large amount of data of the electromagnetic transient model for the single wind generator, it is difficult to realize the multi-unit simulation modeling of large-scale wind farms by power system simulation software. In this paper, the simplified models of single direct drive and doubly-fed wind generator system are proposed, respectively. In order to study the output characteristics of the wind generator system, the components with small inertia constant in the electromagnetic transient model are neglected, and the shafting model, the converter model, and the control loops are simplified and reduced, respectively. Based on the study of the single electromagnetic transient model of wind generators, the simplified simulation models are built by the PSCAD (Power Systems Computer Aided Design) simulation platform, which are carried out under the conditions of constant wind speed, step wind speed, and fault. The output characteristics of the simplified models under different working conditions are compared in detail models. The simulation results show that, within the allowable calculation accuracy range, the dynamic response curves of the single simplified model and the electromagnetic transient model are consistent. The simulation speed can be significantly improved, the time consumption can be reduced, and the simulation speed can be increased more obviously when the number of simulation models increases. Therefore, it can be applied to the simulation research of multi-wind generators in large-scale wind farms.

The AC/DC hybrid microgrid, which takes into account the access requirements of AC and DC sources and loads, optimizes the structure of traditional distribution networks. The application of power electronic transformers as the core of its energy management, with electrical isolation and accurate control of the voltage, current and power flow by the control system, enables the microgrid to achieve a more flexible and stable transmission mode. Because the power electronic transformer combines the power electronic device and the high-frequency transformer, its frequent switching causes the electromagnetic transient simulation to take too long. Therefore, by simplifying control loops and converters, this paper proposes a simplified model for the microgrid system power flow and the dynamic response under exposure to a fault. The mathematical model equivalent simplification method is used in this paper. This method is concise and efficient and does not rely on the performance of a computer or change the program algorithm of the software. The simplified model was built based on PSCAD (Power System Computer Aided Design) simulation software and was carried out under short circuit fault conditions to verify its validity. The comparison of the simulation’s time consumption and accuracy shows that model simplification can significantly improve the simulation speed, with an acceptable error rate, and its dynamic response maintains good consistency with that of the detailed electromagnetic transient model. Therefore, it can be applied to the transient electromagnetic simulation fault analysis of the AC/DC hybrid microgrid.

Microgrids should go into islanding operations to supply power for local critical loads in the event of grid faults. During the operation of the microgrid, the voltage of the point of common coupling (PCC) can be maintained within a certain range by energy storage equipment (ESE). In this work, a direct seamless transfer strategy is developed based on the design of the power and inductor parameters of the three-phase converter in the ESE. When unintentional islanding occurs, the amplitude and frequency of the PCC voltage is affected by the output voltage of the converter, the rated power of the converter, and the voltage drop across the inductor. To ensure the value of the amplitude and frequency of the PCC voltage within the prescribed range, limiters are added to the modulation waves to realize the direct seamless transfer strategy. By analyzing the vector diagram of voltage and current vectors for different loads, the power requirement of the ESE and the voltage drop across the inductor in the converter are obtained. Finally, the design of the limiters’ parameters, analysis of inductor ripple current, and influence of nonlinear load on the PCC voltage are presented for the proposed control strategy.

The converter in a microgrid uses the active power and reactive power (PQ) control strategy when connected to the grid. In the case of failure of large power grid, the converters are required to be connected in parallel under the condition of island to provide power to the load. In this paper, a new control method for the parallel operation of converters based on V/F control is proposed. The V/F control is used to ensure the output voltages have the same amplitude and frequency, then the converters will only produce circulating current caused by phase angle inconsistency. The phase angle self-synchronization strategy is proposed to make sure the phase angle of output voltage of all converters in the system are consistent. First, a large inductor is added to the end of the converter to ignore the line reactance, through this, the measured voltage at the terminal of the converter roughly equals to the voltage of the load, thus, every converter has the same reference of phase angle. Using the proposed phase angle self-synchronization strategy allows the output voltage of every converter to have the same phase angle, so that there is no circulating current between converters, and the power is evenly distributed among the converters. The simulation verification was carried out on the Power Simulation (PSIM) simulation platform, and the experimental verification was implemented on the hardware experimental platform. Both results demonstrate the effectiveness of the proposed strategy. This method is highly reliable and easy to implement, and the circulating current can be reduced effectively.

With the extensive development and use of new energy sources, it has become an urgent issue to solve the problem how to effectively use such energy sources. This paper designs a single-phase electric energy router (SPEER) whose main goal is to solve the problem of optimal operation of the home power system under a high penetration rate of new energy. First, a SPEER structure is presented which has an AC-DC hybrid form to meet the power requirements of all household electrical equipment. Compared with the existing structures, its structural design is more suitable for small-capacity systems, such as home power systems. Next, a reasonable, detailed, and feasible control scheme was designed for each part of the SPEER, so that it has the functions of plug and play, power routing, island detection, and synchronous grid connection, and a seamless coordination management scheme between subsystems was designed. Complete functions make it more intelligent in response to various conditions. Finally, the correctness of the designed SPEER and control strategy was verified by experiment.

The doubly-fed variable-speed pumped storage (DFVSPS) is an effective method to balance the fluctuation of renewable energy generation and is an important means of frequency and voltage regulation of a power grid. Firstly, this paper introduces the structure and mathematical model of the DFVSPS unit. Secondly, the control methods of each switching stage in generating mode and pump mode are proposed, and the simulation study of each stage of DFVSPS switching process is carried out by MATLAB/Simulink. Thirdly, when studying the regulating effect of DFVSPS unit in the power system, due to the high switching frequency of converter in the electromagnetic transient model, the simulation speed is very slow and the data volume is large, so the model of DFVSPS unit needs to be simplified. By analyzing the dynamic behavior of the pumped storage power station, the mathematical model of output power of the DFVSPS unit is established, which includes start-up stage, load ramping stage, stable operation stage, load rejection stage and shutdown stage of generating mode and pump mode. Finally, the simplified model of DFVSPS unit is applied to a simple power system to verify its regulating effect on grid power.

With the aim of improving the consumption capacity of distributed generation (DG) in the distribution network, the control strategy of the flexible multi-state switch (FMSS) for the maximum consumption of distributed generation is proposed. The principle that FMSS improves the consumption capacity of distributed generation is analyzed and verified by simulation. The estimating method for the maximum accessible capacity of distributed generation at the access point is proposed. For complex systems, the multi-objective function for maximizing the consumption of distributed generation was established, and the analytic hierarchy process and entropy weight method were combined to obtain the weight factor. Then, combined with system constraints, the results can be obtained by optimization algorithms. Finally, the control strategy of FMSS for maximum consumption of distributed generation was realized and verified in a simulation.

This paper proposes a seamless transfer strategy based on the droop control strategy for three-phase converter in microgrid, which consists of the voltage limiter and the frequency limiter. In grid-connected mode, both the two limiters don't work, and the VSC is controlled by PQ control, transmitting constant power between micro-sources and power grid. When the unplanned islanding occurs, the PCC voltage and frequency may exceed the allowable range because the reference of active power and reactive power are not equal to the loads power. Then the voltage limiter and the frequency limiter begin to take effect, ensuring the power supply quality for loads. The difference between the input signal of these two limiter and the output signal will pass through the proportional regulator, and the new references of active power and reactive power can be obtained according to the droop curve. After the islanding detection detects the islanding condition, the control strategy will be changed to the droop control. All the converters can work in parallel and provide the voltage and frequency supply for loads. At last, the simulation results verified the proposed seamless transfer strategy.

During the operation of microgrid, especially when the unplanned islanding occurs, the voltage of the point of common coupling (PCC) needs to be maintained within a certain range, otherwise it would affect the operation of loads in microgrid. This paper proposes a seamless transfer strategy based on the inductance parameter design for three-phase converter in microgrid, which considers both the fundamental component of voltage on the inductance and the ripple current in the inductance. In grid-connected mode, the PCC voltage is supported by the grid. When the unplanned islanding occurs, the PCC voltage is affected by the output voltage of converter and the voltage on the inductance. According to the single phase equivalent circuit, analyzing the phasor diagram of voltage and current vector, considering the prescribed range of PCC voltage and satisfying the requirement of the magnitude of ripple current, the inductance parameter is designed. At last, the simulation result shows that the designed inductance can ensure the PCC voltage does not exceed the prescribed range and restrain the ripple current.

It is a common practice for storage batteries to be connected to DC microgrid buses through DC-DC converters for voltage support on islanded operation mode. A feed-forward control based dual-loop constant voltage PI control for three-branch interleaved DC-DC converters (TIDC) is proposed for storage batteries in DC microgrids. The working principle of TIDC is analyzed, and the factors influencing the response rate based on the dual-loop constant voltage control for TIDC are discussed, and then the method of feed-forward control for TIDC is studied to improve the response rate for load changing. A prototype of the TIDC is developed and an experimental platform is built. The experiment results show that DC bus voltage sags or swells caused by load changing can be reduced and the time for voltage recovery can be decreased significantly with the proposed feed-forward control.

This study proposes an analysis and specification of current loop tracking error in the grid-connected voltage source converter with direct current control. In practical applications, it is a common phenomenon that the current control loop sees a quite significant command-tracking error while the actual output current of the converter is still satisfactory, for example, for static var generators or parallel active power filters, it is exactly the reactive current and/or the harmonic current that are needed to compensate the load current. In this study, a detailed analysis is presented to investigate this confusing issue. Based on the obtained current loop transfer function, analytical expressions of the current tracking error are derived. The reasons why a significant current tracking error exists together with satisfactory compensation result are revealed subsequently. The current tracking error has a relationship with the source voltage. An over-shoot start current appears because of the current tracking error. Two new methods used to suppress the over-shoot current are also presented. Finally, the hardware experimental results verify the analysis and the methods of suppressing the over-shoot current.
