- In the last years, the increased environmental awareness is calling for the transition from vehicles powered by Internal Combustion Engines (ICEs) toward Electric Vehicles (EVs). Nevertheless, the wide penetration of such technologies is limited by the impact EV Charging Stations (EVCSs) have on the distribution grid. The management of EVCSs could benefit from the use of the energy produced by Renewable Resources, appropriately coupled with storage system, through the infrastructures offered by Smart Grids (SGs). The validation of these architectures can be performed in simulation or emulation environments. Whilst such approaches are profitable for validating the sensitivity of different architectures to parameters changes, sometimes the use of over-simplified models could bring to unreliable results. For this reason, a testing facility for the characterization of the integration of EVCSs in SGs has been designed and deployed at the eLUX lab of the University of Brescia, Italy. The testing facility includes an EVCS (22 kW), an EV (Renault Zoe), a controllable photovoltaic (PV) field (10 kWp) and a Battery Energy Storage System (BESS) (20 kWp, 23.5 kWh). The possibility to integrate a real-time emulator (OPAL-RT) for Hardware-In-the-Loop (HIL) emulation allows to easily expand the capabilities of the testing facility. © 2019, Springer Nature Switzerland AG.

Tidskriftsartikel (refereegranskat)abstract
- The increasing presence of intermittent distributed generation (DG) based on renewable energy sources (RESs) is heavily affecting the operation and management of modern distribution grids. Even though the use of distributed energy storage systems (DESSs) and the integration of advanced demand response (DR) programs are expected to mitigate this problem, security, safety, economic, and technical reasons are limiting the tests of these mechanisms in working systems. The test in simulation and emulation environments has proved to be an effective solution for the development of advanced control and protection schema, but their use for the simulation of the typically unpredictable behavior of end-users seems at least questionable. This paper proposes a testing framework for the analysis of experimental control strategies of distributed energy systems. The framework, based on a service-oriented architecture, can be easily interconnected to different systems, including renewable generators and storage systems. This framework can be used to analyze the performance of real energy systems, working in near-To-real conditions. The framework has been used for a pilot test on a subset of the facilities of the eLUX laboratory of the University of Brescia. The proposed framework allows analyzing the energy performance of this system by means of proper key performance indicators (KPIs). The efficiency analysis of a battery energy storage system (BESS) is presented, by proposing KPIs to evaluate the effect of different control strategies. Further KPIs are also used to evaluate the effectiveness of the BESS for improving the energy self-consumption of a photovoltaic system. © 1963-2012 IEEE.
