Introduction. Energy storage systems play an increasingly important role in modern power systems. Battery energy storage system (BESS) is widely applied in user-side such as buildings, residential communities, and industrial sites due to its scalability, quick response, and design flexibility [1], [2].
FACED with the dual pressure of energy and environment, Europe [1], the United States [2], and China [3] have respectively set a goal to generate 100%, 80%, and 60% of electricity by renewable sources until 2050. Different from the traditional energy system in which diverse energy sources such as electricity, heat, cold, and gas are
