Comparative study of coordinated photovoltaic and battery control strategies on the battery lifetime in stand-alone DC microgrids

Battery energy storage systems (BESSs) are often integrated into stand-alone dc microgrids (dcMGs) with photovoltaic (PV) system to enhance the microgrid reliability and prevent the dc bus voltage instability arising from PV power generation intermittency and load demand transients. The battery degr...

Description
Summary:Battery energy storage systems (BESSs) are often integrated into stand-alone dc microgrids (dcMGs) with photovoltaic (PV) system to enhance the microgrid reliability and prevent the dc bus voltage instability arising from PV power generation intermittency and load demand transients. The battery degradation rate is critically influenced by its utilization manner. The contribution of this paper is to compare various standalone dcMG coordinated control strategies for the PV and BESSs, and analyze their efficacy and impact on the battery lifetime. The battery lifetime investigation is carried out via simulation case studies with yearly irradiance and load profiles.
