The presence and evolution of static power converters in electric grids are growing on a daily basis. Starting from the most used voltage source converter (VSC), passing through the use of multilevel converters, the most recent configuration is the so-called modular multilevel converter (MMC). Because of its intrinsic advantages, it is used not only in high-voltage systems but also in low- and medium-voltage ones to interface renewable energy sources such as photovoltaic (PV) panels. Several configurations and maximum power point tracker (MPPT) algorithms have been proposed and analyzed for MMC-PV-based systems. However, when using distributed MPPTs, partial shading conditions cause a problem. The PV panel can be directly connected to the MMC using its dc link or submodule. Based on this configuration, this paper proposes a novel control strategy that tracks both the ac grid current and ac circulating current for a single-phase low-voltage system to obtain the maximum power under any irradiance condition. The effectiveness of the proposed control strategy is demonstrated through time-domain simulation results.

The increasing integration of renewable energies reduces the inertia of power systems and thus adds stiffness to grid dynamics. For this reason, methods to obtain virtual inertia have been proposed to imitate mechanical behavior of rotating generators, but, usually, these methods rely on extra power reserves. In this paper, a novel ancillary service is proposed to alleviate frequency transients by smoothing the electromagnetic torque of synchronous generators due to change of active power consumed by loads. Being implemented by grid-tied inverters of renewables, the ancillary service regulates the reactive power flow in response to frequency transients, thereby demanding no additional power reserves and having little impact on renewables’ active power generation. Differently from the active power compensation by virtual inertia methods, it aims to low-pass filter the transients of the active power required to synchronous generators. The proposed ancillary service is firstly verified in simulation in comparison with the virtual inertia method, and afterwards tested on processor by controller-hardware-in-the-loop simulation, analysing practical issues and providing indications for making the algorithm suitable in real implementation. The ancillary service proves effective in damping frequency transients and appropriate to be used in grid with distributed power generators.

Lithium ion batteries are being used in an increasing number of applications. However, one of their major weaknesses is their sensitivity to temperature. Indeed, their safety and aging strongly depend on their temperature. In order to control cell temperatures, each cell in a battery pack is usually equipped with a thermal sensor. This paper proposes an integrated electro-thermal model that is capable of predicting the thermal behavior of a battery cell based only on its current and ambient conditions. The proposed model was tuned and validated by means of experimental results. The obtained precision is sufficient to predict the temperature of a battery with an acceptable accuracy considering the low complexity of the proposed model.

Nowadays, lithium ion batteries are increasingly spreading in different areas and therefore, it is very important to understand their aging behavior. According to the technical literature, battery aging can be dissociated in calendar aging and cycle aging. Calendar aging, in particular, depends on the temperature and state of charge (SoC). In addition to the previous factors, cycle aging also depends on the current rate, and charge/discharge cut-off voltages. In the literature, only a few papers have considered battery aging as a function of the charge/discharge current rate, but they agree that a higher current rate leads to faster battery aging. In any case, all of the tests have been conducted in a climactic chamber with a constant room temperature. However, even if the room temperature is controlled, for high current rates, the temperature of the battery cell increases, which makes it impossible to distinguish the aging due to the current from that due to the temperature. For this reason, in the present work, the authors focused on the lithium ion battery aging due to the current rate while maintaining a constant battery temperature using opportunely controlled Peltier cells. In this way, an interesting results was obtained, i.e. the cycle aging is not dependent on the current rate.

In the past, the diffusion of electric vehicles (EVs) has been hindered by energy storage limits. In fact, these are the reason for the limited EV range and the consequent range anxiety of their drivers. Thanks to constant improvements in storage system technologies over the years, in terms of both energy and power density, lithium-ion batteries (LiBs) now guarantee vehicle ranges higher than 150 km for small vehicles. Another important improvement has been achieved by the hybridisation of LiBs with other storage technologies such as electric double-layer capacitors or lithium-ion capacitors. By adding an additional storage unit (ASU) to the EV battery system, the overall efficiency increases, with a consequent gain in the vehicle's expected range. In a previous paper, an optimal sizing procedure was proposed, through which it is possible to calculate the optimal ASU mass that maximises the EV range for a given vehicle, ambient conditions, and driving cycle, which was considered to be known a priori. In the present work, a real-time implementation of the control strategy on which the optimal sizing procedure was based is proposed and analysed using the results of simulation tests.

Nowadays, energy storage systems, such as batteries, are spreading in many applications. Among the kinds of batteries, the lithium-ion technology is one of the most promising solutions. Considering the photovoltaic (PV) plants, it is very important to perform a correct sizing of the battery pack to both maximise the self-consumption and minimise the total costs. In general, PV plants need a dc–dc converter to maximise the electric power that can be extracted from PV panels and a dc–ac converter to connect them to the ac grid. The battery pack can be connected in three different ways: dc coupled and ac coupled using a dedicated converter or through a direct connection on the dc-link between the dc–dc and dc–ac converters. In the present study, the last solution, without any dedicated converters, is used and a simple control strategy to both maximise the power extracted from the PV panel and regulate the charging/discharging of the battery is proposed.

Up to few years ago, one of the main problems in the optimal design of a battery energy storage system (BESS) was the availability of both the generation (e.g. renewable sources) and load power profiles of the considered plant. This paradigm has limited the potential of BESSs to drive down overall energy costs and reduce carbon emissions. Nowadays, the exponential growth of data available on the industrial plants has opened the way to new possibilities and opportunities. In addition, BESSs are a viable opportunity to start transforming existing plants with an incremental hybridization of the plant topology. In light of the above, this work develops a commissioning tool that, starting from the data collected on the field, provides the final users the optimal dimensioning of any BESS - according to the target performances required bv the specific application.

In micro-grids, due to the heavy penetration of distributed energy resources (DERs), especially renewable energy sources (RESs), the characteristic inertia of the system has been decreasing with respect to the total power capacity. In a weak grid, a high step variation of the load leads to a hard transient of frequency. This could imply stability issues for the grid and specific problems for sensitive loads. In order to face this problem, in the technical literature, several algorithms introducing virtual inertia in the system have been proposed. Since, these algorithms are based on the assumption that an equivalent inertia has to be simulated, they need to exchange active power with the network. When this function is implemented in a PV system, a power reserve or an additional storage unit has to be used. In this paper, a technique to increase the transient stability of the generation system, based only on the exchange of reactive power, will be proposed. Its feasibility is demonstrated by means of numerical simulations.

Pulse-width modulation is one of the most common modulation strategies. Nevertheless, some issues about the harmonic content of the output voltage and current are still debated. In the present paper, the space vector and zero component are used for harmonic analysis of the naturally sampled three-phase PWM. An overall analytical formulation of the Fourier series is derived, through which a detailed evaluation of the ripple shifting among the phases is carried out. Simulations support the consistency of the proposed analysis.

Modular converters are of particular interest for high-power applications where the usage of a certain number of modules instead of a single converter allows to obtain better power quality and dynamic behavior, as well as higher reliability. In this paper a detailed analysis of harmonic distortion in modular three-phase converters is performed. Analytical expressions of voltage harmonics are provided and analyzed in terms of space vector and zero component. Commutation interleaving is also considered and its effects on space vector and zero component are studied in detail. A modular three-phase converter constituted by four modules with 2+2 redundancy is considered as case study. Analytical expressions and simulation results are presented and compared.

Nowadays, electric vehicles (EVs) are of great interest over the world. In the past, the diffusion of EVs was impeded because of the limits of energy storage units, which reflect in vehicle range limited extension. In recent years, a significant progress was made in terms of power and energy density thanks to the lithium based batteries that can guarantee vehicle ranges higher than 100 km. Another further step can be done by coupling more than one storage technology and leading to an increased efficiency and extension of the vehicle range. In this paper, the effectiveness of adding another storage unit to a lithium ion battery is investigated for different EVs and driving cycles. Furthermore, a methodology procedure, based on the knowledge of the test driving cycle, and parameters of the EV, is proposed to find the optimal size of the auxiliary storage, that maximizes the EV range.

Nowadays, battery storage systems are very important in both stationary and mobile applications. In particular, lithium ion batteries are a good and promising solution because of their high power and energy densities. The modeling of these devices is very crucial to correctly predict their state of charge (SoC) and state of health (SoH). The literature shows that numerous battery models and parameters estimation techniques have been developed and proposed. Moreover, surveys on their electric, thermal, and aging modeling are also reported. This paper presents a more complete overview of the different proposed battery models and estimation techniques. In particular, a method for classifying the proposed models based on their approaches is proposed. For this classification, the models are divided in three categories: mathematical models, physical models, and circuit models.

Today's residential battery energy storage systems (BESSs) are off the shelf products used to increase the self-consumption of residential photovoltaic (PV) plants and to reduce the losses related to energy transfer in distribution grids. This work investigates the economic viability of adding a BESS to a residential grid-connected PV plant by using a methodology for optimising the size of the BESS. The identification of the optimal size which minimises the total cost of the system is not trivial; indeed, it is a trade-off between OPEX and CAPEX, which are mainly affected by the battery technology, usage profile, expected lifetime, and efficiency. Here, an analysis of the opportunity to install a storage system together with a grid-connected residential PV plant is performed. Three typical low-voltage prosumers (Italy, Switzerland, and the UK) are investigated in order to take into account the different legislative and tariff framework over Europe. Numerical results reported here show that present costs of storages are still too high to allow an economic convenience of the storage installation. Moreover, an indication of the necessary incentives to allow the spreading of these systems is given.

Energy storage systems are spreading both in stationary and transport applications. Among innovative storage devices, lithium ion capacitors (LiCs) are very interesting. They combine the advantages of both traditional electric double layer capacitors (EDLCs) and lithium ion batteries (LiBs). The behavior of this device is much more similar to ELDCs than to batteries. For this reason, several models developed for traditional ELDCs were extended to LiCs. Anyway, at low temperatures LiCs behavior is quite different from ELDCs and it is more similar to a LiB. Consequently, EDLC models works fine at room temperature but give worse results at low temperatures. This paper proposes a new electric model that, overcoming this issue, is a valid solution in a wide temperature range. Based on only five parameters, depending on polarization voltage and temperature, the proposed model is very simple to be implemented. Its accuracy is verified through experimental tests. From the reported results, it is also shown that, at very low temperatures, the dependence of the resistance from the current has to be taken into account

This paper shows that the space-vector approach is an eminent and powerful tool in three-phase analysis. It is able to manage in a unitary way the sinusoidal, distorted and transient conditions. Its complex Fourier series implements a formal unification between unbalance and distortion; such unification is conceptually significant and leads to simplification of principle, as well as powerful analytical processing. Examples illustrate the effectiveness of the complex Fourier series as analytical tool in different application areas.

This paper introduces a new control strategy to realize a virtual synchronous generator. The proposed control strategy is based on virtual impedance and band-pass damping algorithms to achieve the electro-mechanical characteristics of synchronous generator for the grid converter. Differences between new and traditional method on impedance emulation, and differences between traditional pure proportional damping algorithm and new band-pass damping algorithm are discussed as well. Additionally, detailed analysis of the components of synchronous generator is given, also the roles of the various parts of synchronous generator in the power system stability control are explained. The behavior of designed control strategy is validated by both simulations and experiments made on a 2kW grid-connected inverter.

Electrochemical storage devices are spreading in many applications. Nevertheless, the data given by the manufacturers are often few and not homogenous. Using these data a correct sizing for a given application results very difficult and usually the designers makes a rough design in which the expected lifetime is not known and the costs are not optimized. This situation depends, mainly, on the lack of knowledge in modeling and studying electrochemical storage devices. In this paper, the authors underline the necessity of an integrated model for the definition of the nominal data of a storage device. Moreover, starting always from the solution of an integrated model, they propose a methodology for a correct sizing of a storage unit for a given application.

Lithium-ion batteries are a key technology for current and future energy storage, whether they are used for mobile or stationary application. In particular, they play an important role for the electrification of mobility due to their high power and energy density and therefore their battery lifetime prediction is a fundamental aspect for successful market introduction. The ageing data provided by the battery manufacturers result from standard ageing tests. For this reason, it is very important to link, in the way as simple as possible, the effect of driving cycles (urban, extra-urban, combined) with the ageing of the batteries. The aim of this work is to investigate on the effect of driving cycles on the batteries lifetime through tests performed on different cells for different kinds of cycle. Afterwards, simulation tests are made in order to estimate the battery lifetime for different driving cycles of the electric vehicle.

Lithium-ion batteries are a key technology for current and future energy storage in mobile and stationary application. In particular, they play an important role in the electrification of mobility and therefore the battery lifetime prediction is a fundamental aspect for successful market introduction. Numerous studies developed ageing models capable of predicting battery life span. Most of the previous works compared the effect of the ageing factors to a battery’s cycle life. These cycles are identical, which is not the case for electric vehicles applications. Indeed, most of the available information is based on results from laboratory testing, under very controlled environments, and using ageing protocols, which may not correctly reflect the actual utilization. For this reason, it is important to link the effect of duty cycles with the ageing of the batteries. This paper proposes a simple method to investigate the effect of the duty cycle on the batteries lifetime through tests performed on different cells for different kinds of cycle. In this way, a generic complex cycle can be seen as a composition of elemental cycles by means of Rainflow procedures. Consequently, the ageing due to any cycle can be estimated starting from the knowledge of simpler cycles.
