摘要

Diesel hybrid mini-grids with high penetration of renewables have the potential for reduced operation costs and environmental impacts. However, the fluctuating characteristics of wind and Photovoltaics (PV) and the large variations of the frequently unbalanced mini-grid loads, result in additional challenges for optimizing the operation of the diesel genset(s). In such a case, a Battery Energy Storage System (BESS) can be very beneficial. This paper presents a control system of a BESS that allows it to operate in multiple modes. In the genset support mode, it balances the load, compensates for reactive power and forces the genset(s) to operate in a desired power range. In the grid forming mode, it supplies balanced voltages to highly unbalanced loads. Simulation results are provided.
