Integrating Hybrid Off-grid Systems with Battery Storage: Key Performance Indicators

A clear opportunity exists for the integration of Battery Energy Storage Systems (BESS) in hybrid off-grid applications, i.e., isolated grids with renewable sources (e.g. photovoltaic, wind) and small-scale diesel generators. In these applications, renewable sources have the potential to reduce fossil fuels derivatives consumption and reduce Greenhouse Gases (GHG) emissions. BESS present the capability of maximizing the integration of renewable energy and, consequently, further offset the use of diesel-fired generating units. Therefore, this work advances an operating strategy for the day-ahead planning of the generation units in the microgrid based on the use of Key Performance Indicators (KPIs).
