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.
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 optimal configuration of energy storage capacity is an important issue for large scale solar systems. a strategy for optimal allocation of energy storage is proposed in this paper. First various scenarios and their value of energy storage in PV applications are discussed. Then a double-layer decision architecture is proposed in this article.
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.
