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 energy storage system power is expressed as P t P t P tESS s r ( ) ( ) ( )= âˆ' (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.
