In this paper, the flexibility of hybrid AC-DC distribution networks is exploited to coordinate multiple Distributed Energy Resources (DERs) with the aim of promptly restoring unexpected power imbalances caused by intermittent Renewable Energy Sources (RESs) and loads. Given the potential large-scale nature of the problem, the AC distribution network is decomposed into non-overlapping areas named clusters, equipped with MicroGrids (MGs) and non-dispatchable units, and interconnected also by the DC network. Each cluster is endowed with a Model Predictive Controller designed to compensate the local active power variability by requesting balancing services to the local MGs. A supervisory layer is designed and activated to optimally transfer power through the controllable DC links guaranteeing enough operative margins to each cluster. The designed architecture is tested on a benchmark grid composed of the IEEE 37-bus and 13-bus systems, connected by a multi-terminal DC network. The reported numerical results witness the effectiveness of the proposed approach.

Microgrids are composed of distributed energy resources (DERs), storage devices, electric vehicles, flexible loads and so on. They may either operate connected to the main electricity grid (on-grid operation) or separated from the grid (islanded operation). The outputs of the renewable energy sources may fluctuate and thus can cause deviations in the voltage magnitudes especially at islanded mode. This may affect the stability of the microgrids. This paper proposes an optimization model to efficiently manage controllable devices in microgrids aiming to minimize the voltage deviations both in on-grid and islanded operation modes. RSE Distributed Energy Resources Test Facility (DER-TF), which is a low voltage microgrid system in Italy, is used to verify the algorithm. The test system’s data is taken through an online software system (REDIS) and a harmony search based optimization algorithm is applied to control the device parameters. The experimental results show that the harmony search based optimization approach successfully finds the control parameters, and can help the system to obtain a better voltage profile.

DC Microgrids are receiving a growing interest thanks to the advantages offered by the integration of renewable sources. This paper presents an optimal hierarchical control for DC microgrids that performs multiple control objectives, like (i) voltage regulation, (ii) minimization of the losses, (iii) power-sharing, (iv) energy storage management and (v) economic savings. The hierarchical control is made up of sequential actions so that, at the higher level, the optimal plan for power generators and for storage systems is generated and then sent to the model predictive control. This controller is the core of this study and it has three main functions such as (i) voltage regulation, (ii) energy storage management and (iii) tracking of the optimal planning, taking into account the different characteristics of the DC components and generating the references for the low-level controller. The proposed control based on optimization has been validated with good results on the real low-voltage DC microgrid in RSE.

The EU is committed to reducing greenhouse gas emissions to 80-95% below 1990 levels by 2050. To accomplish this goal the share of renewable energy sources have to increase significantly. Challenges related to keeping a high security of supply have raised while the share of intermittent renewable electricity generation is increasing. The increasing level of RES production leads to higher volatility in market prices. The main challenges lay within the modeling and simulation of the random variables. Therefore, the assessment of the operation of the entire micro-grid should be studied while constructing different test scenarios under uncertainty of the market prices and micro-grid configuration. This paper constructs different tests to investigate the integration of Electric Energy Storage unit technologies in a micro-grid. The assessment of the impact on the micro-grid, like congestion or voltage problem, are analyzed when the EES units are owned by a separate business entity called aggregator or a grid owner.

This paper deals with the design of a robust and decentralized passivity-based control scheme for regulating the voltage of a DC microgrid through boost converters. A Krasovskii-type storage function is proposed and a (local) passivity property for DC microgrids comprising unknown ZIP (constant impedance ‘Z’, constant current ‘I’ and constant power ‘P’) loads is established. More precisely, the input portvariable of the corresponding passive map is equal to the first-time derivative of the control input. Then, the integrated input port-variable is used to shape the closed loop storage function such that it has a minimum at the desired equilibrium point. Convergence to the desired equilibrium is theoretically analyzed and the proposed control scheme is validated through experiments on a real DC microgrid.

The growing diffusion of renewable energy sources is leading to a considerable revision of the distribution network. In this context, the adoption of direct current distribution grid can bring benefits to the hosting capacity and energy efficiency. However, the protection of such network involves many challenges, especially in case of LVDC microgrids with more than one feeder. The traditional protection schemes used for AC grid are not able to isolate faults and to protect the components of the DC grid. This paper deals with the analysis and design of the protection scheme for a low voltage DC microgrid, in presence of different renewable generators, energy storage systems, loads and front-end converter with the AC grid. The proposed centralized protection scheme overcomes issues of fast fault clearing time, cost effectiveness and selectivity in the case of pole-to-pole fault.

In recent years, DC distribution grids have become increasingly popular because of the interest in the diffusion of distributed renewable energy. In this scenario, DC distribution grids are also favored because of the increased use of batteries and power electronic loads. The main limit to the spread of DC grids is their protection devices, which still present several problems. At present, protection devices are represented by traditional mechanical breakers or static electronic components. The first, which interrupt DC currents, have good reliability but need maintenance and have long intervention periods. In contrast, electronic switches are fast and reliable, but they reduce the efficiency because of their voltage drop. In this scenario, some hybrid breakers have been proposed to obtain the advantages of both devices. The previous solutions of hybrid breakers still suffer several critical issues and, usually, are not capable of protecting a system from short circuits without significantly reducing their lifetime. In this paper, a new low-voltage hybrid circuit breaker topology is proposed. The procedure to dimension all of the active and passive components in the device is analyzed, and the effectiveness of the proposed solution is proven by means of experimental results obtained using a prototype.

Over the recent years, low-voltage dc (LVDC) distribution systems have become increasingly interesting. One of the main problems in their diffusion is the realization of reliable protection systems ensuring selectivity and security to the loads. Several solutions to this problem are studied in the current literature and are mainly focused on the design and integration of new protection devices. Nevertheless, for some faults, it is possible to use traditional protection devices if proper control strategies are used on the power converters. In this paper, the ground fault of one of the dc poles is considered for grids operated with the neutral ground connected on the ac side and isolated on the dc side. In these conditions, if, as usual, a voltage source converter (VSC) is used as an interface between ac and dc grids, the IGBTs of the VSC are capable neither of limiting nor of blocking the fault current. In this paper, the integration of a proper control strategy implemented on the VSC with the protection devices is proposed to allow the system to interrupt, clearing the fault, saving the power converter. The proposed strategy ensures selectivity and security to the loads because it implies the interruption only of the faulty feeder of the dc microgrid. In this paper, the proposed strategy is tested by means of numerical simulations and experimental results, thus proving its good performances.

Growing number of inverter-based distributed energy resources (DERs) and sensitive loads increase the need for coordinated power management activities in islanded operation of microgrids. Especially low voltage networks have low inertia and high R/X ratio, causing instability due to fluctuations in distributed generation (DG) and local voltage problems in islanded operation. This study investigates management of DERs that operate in current mode for providing voltage regulation support to master unit(s) in islanded operation of microgrids. A special focus was set on local voltage issues in low voltage (LV) network feeders. Field experiments in a large test facility highlighted management accuracy and corrective impact potential of DERs connected to different parts of a feeder.

Distributed energy resources (DERs) can provide a number of functions to be used in grid services with proper establishment of control and communication systems. However, there are neither general standards for vendor independent integration of these assets in management activities, nor common consideration of specific flexibilities that different DERs have. This paper investigates characterization and comparison of individual power and energy management flexibilities of different types of distributed energy resources. Emerging DER capability identification approaches are used to highlight contrasting differences between several energy storage and distributed generation options. Experiments were conducted in a low voltage test facility to compare flexibility limits using the same control and communication infrastructure.

This paper deals with the design of a robust decentralized control scheme for voltage regulation in boost-based DC microgrids. The proposed solution consists of the design of a suitable manifold on which voltage regulation is achieved even in presence of unknown load demand and modeling uncertainties. A second order sliding mode control is used to constrain the state of the microgrid to this manifold by generating continuous control inputs that can be used as duty cycles of the power converters. The proposed control scheme has been theoretically analyzed and validated through experiments on a real DC microgrid.

Nowadays, the integration of Energy Storage Systems in the electrical grid is a fundamental key to support the transition toward a reliable decentralized, renewable energy supply and electrochemical accumulators are one of the most promising storage technologies for many grid-connected applications. However, many applications, for example offering ancillary services, could increase the strain on the batteries causing a degradation of performances. Thus, the use of batteries coupled with supercapacitors, that have a higher specific power and a longer lifetime, allow a better management of the battery in many grid-connected applications. The article describes the results of characterization and ageing tests executed in order to verify the improvements, in terms of performances and lifetime, of a hybrid lithium-ion battery-supercapacitors system compared to a system composed by a battery operated alone.

In this paper, we describe a control strategy for a photovoltaic (PV) power plant equipped with an energy storage system (ESS), based on lithium-ion battery. The plant consists of the following units: the PV generator, the energy storage system, the DC-bus and the inverter. The control, organised in a hierarchical manner, maximises the self-consumption of the local load unit. In particular, the ESS action performs power balance in case of low solar radiation or surplus of PV generation, thus managing the power exchange variability at the plant with the grid. The implemented control strategy is under testing in RSE pilot test facility in Milan, Italy.

In the past few years the diffusion of renewable energy generators caused a transformation of the electrical system from the traditional centralized structure, with all the generating plants in high voltage transmission system, to a structure in which the generators are distributed on medium voltage and low voltage distribution system. The operation of electric grid requires a continuous real-time balance between the demand and the produced power; a balancing which is rather critical considering the massive penetration of non-programmable renewable generators into the grid. In this paper we discuss a control strategy for a photovoltaic generator including energy storage system to regulate the exchange of power between the costumer and the grid.

The problem considered in this paper is the design of a control system for semi-active suspension fully oriented to the handling objective. For better understanding the handling behavior of a suspension, the paper proposes a model of interaction between the suspension dynamics and the tire-road forces. On this basis an analysis focused on the evaluation metrics for handling performances is presented. The analysis highlights that not only the minimization of the overall tire deflection variations may improve the handling properties but also the shape of those variations has influence on them. The rest of the paper is devoted to the study of handling optimal performances based on optimal predictive control with road preview. The final contribution is a new algorithm for handling maximization which provides a great improvement compared to common passive suspension and to classical semiactive control such as Groundhook algorithm.
