Review on photovoltaic with battery energy storage system for power supply to buildings: Challenges and opportunities

Photovoltaic (PV) has been extensively applied in buildings, adding a battery to building attached photovoltaic (BAPV) system can compensate for the fluctuating and unpredictable features of PV power generation. It is a potential solution to align power generation with the building demand and achieve greater use of PV power. However, the BAPV with battery energy storage system (BESS) is now still facing significant challenges in economic system design, high-efficiency operation, and accurate optimization. This paper aims to present a comprehensive review on the effective parameters in optimal process of the photovoltaic with battery energy storage system (PV-BESS) from the single building to the energy sharing community. The key parameters in process of optimal for PV-BESS are recognized and explained. These parameters are the system's applicability, optimization methods, optimization objectives, and optimization constraints. Moreover, details on the advantages and disadvantages of different optimization methods for the PV-BESS have been analyzed. The current issues and existing challenges are highlighted to identify the gaps for future research. This paper provides a clear picture to the researchers in the field of the PV-BESS and a reference for researchers to understand and further investigate the PV-BESS in depth.
