Seasonally variant deployment of Electric battery Storage systems in active distribution networks

Abstract

Due to the aging of network infrastructure, the increasing load demand in distribution networks together with the increased installation of PVs (Photovoltaic) in the MV and LV network, there is a need for network reinforcement. As load growth congests the grid, the strategic placement of electric storage systems can be an alternative to or contribute to a deferral of grid investments. To study this, an optimization problem solving the dual-purpose deployment of prosumers' level battery storage system has been formulated and will be presented in this paper. The MV/LV substation loadings are compared for the 0% prosumers and 100% prosumers scenarios with PV-battery system. The results of the analysis show that the absolute peak at secondary substation decreases by 8.74% and the average day peak drops by 17% while the total annual energy drawn from the grid reduced by 8.41% with the 100% prosumers scenario. Furthermore, by using household level battery systems for peak shaving of local loads one can achieve a deferral of overloading by 3 years at MV/LV substation
