Systematic Techno-Economic Analysis of Medium-Voltage PV-BES Prosumers Operating Under NEM Policy

Net-metering (NEM) is one of the most widely known support mechanisms aiming to promote the installation of distributed photovoltaic (PV) systems. However, due to the increasing penetration of PVs, challenges related to the secure operation of the power system are emerged. For this reason, battery energy storage (BES) systems are installed alongside PVs to tackle these technical problems. In this paper, a systematic assessment analysis of NEM policy in medium-voltage (MV) prosumers with PV-BES systems, e.g., university campuses, hospitals, etc., is conducted in both technical and economic terms. In the analysis, annual generation and consumption timeseries of university campuses of the Democritus University of Thrace, Greece, are indicatively employed and various scenarios of PV-BES systems are investigated, to evaluate the profitability of NEM policy in MV PV-BES prosumers and consequently determine the optimal investment plan in monetary terms.
