The process of capacity allocation of solving optimization model using PSO According to the capacity configuration model in Section 2.2, Photovoltaic penetration and the energy storage configuration are nonlinear.
Establish a capacity optimization configuration model of the PV energy storage system. Design the control strategy of the energy storage system, including timing judgment and operation mode selection. The characteristics and economics of various PV panels and energy storage batteries are compared.
Impact of PV panel types on capacity allocation with ESS The allocation of energy storage in the PV system not only reduces the PV rejection rate, but also cuts the peaks and fills the valley through the energy storage system, and improves the economics of the whole system through the time-sharing electricity price policy.
However, considering the economy, since the storage cost is higher than the power purchase cost in the trough period, when the photovoltaic power generation storage capacity is enough to offset the demand in the peak period, it will not continue to store energy and choose to abandon the PV.
