摘要：

Decentralized energy storage systems (ESSs) can provide great advantages to low-voltage (LV) distribution networks, enhancing the further penetration of photovoltaic (PV) systems in existing electrical grids. An ESS can locally absorb the PV produced energy during periods of high solar irradiation, thus alleviating potential overvoltages in distribution system, caused by reverse power flow. This work investigates the impact of battery ESSs operation when installed in residential PV prosumers. The charging process of the battery is activated when PV power exceeds a certain power threshold, mitigating the generation peaks in the grid. A sizing method is developed to estimate the capacity of ESSs, aiming to maximize prosumer self-consumption ratio (SCR). The proposed methodology is tested in a real LV network with increased PV integration. Results verify the effectiveness of the developed method. Overvoltages are successfully avoided while prosumers' SCR is maximized and storage utilization is preserved high. The methodology may constitute a useful tool for both distribution system operators and prosumers having storage systems.
