Secondly, to minimize the investment and annual operational and maintenance costs of the photovoltaic–energy storage system, an optimal capacity allocation model for photovoltaic and storage is established, which serves as the foundation for the two-layer operation optimization model.
And the installed capacity of photovoltaic and energy storage is derived from the capacity allocation model and utilized as the fundamental parameter in the operation optimization model.
Table 5 illustrates that the surplus electricity generated by a PV system without energy storage can only be sold online, which is an economically inefficient strategy, and at this time the annual most comprehensive cost is $4380.33. Two types of energy storage batteries are available for users of the PV–energy storage system.
The O&M cost of a PV power generation system is contingent upon its output power, whereas the O&M cost of an energy storage system is dependent upon the number of cycles of charging and discharging.
