Abstract—In this paper, we study the problem of determining the size of battery storage used in grid-connected photovoltaic (PV) systems. In our setting, electricity is generated from PV and is used to supply the demand from loads. While prior work offers some insights, researchers typically consider only a single sizing approach. The objective model for maximizing the financial proceeds of the PV plant, the system for the storage of energy, and a power grid. . tion, energy capacity, and power rating of distributed battery energy storage systems at multiple voltage levels to accomplish grid control and reserve provision.
