Power and capacity configurations are calculated at different confidence levels; the degrees of power satisfaction and capacity satisfaction are used to evaluate the energy storage configuration results, and the optimal energy storage system configuration for the PV power station is obtained.
The energy storage capacity configuration is the one Scan for more details Honglu Zhu et al. Research on energy storage capacity configuration for PV power plants using uncertainty analysis and its applications 609 of the hotspots in current study [8, 9, 10].
The optimal configuration capacity of photovoltaic and energy storage depends on several factors such as time-of-use electricity price, consumer demand for electricity, cost of photovoltaic and energy storage, and the local annual solar radiation.
The energy storage system power is expressed as P t P t P tESS s r ( ) ( ) ( )= − (13) where Ps (t) is the forecasted PV power of the plant at time t, and Pr (t) is the actual PV power of the plant at time t. When Ps (t)> Pr (t), the forecasted PV power of the plant is greater than the actual power, and the energy storage system discharges.
As PV power outputs have strong random fluctuations and uncertainty, it is difficult to satisfy the grid-connection requirements using fixed energy storage capacity configuration methods. In this paper, a method of configuring energy storage capacity is proposed based on the uncertainty of PV power generation.
The actual operating conditions and battery life should be considered in the optimal configuration of energy storage, so that the configuration scheme obtained is more realistic.
