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.
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.
When the day lighting conditions are fixed, the three relationships are directly related to the magnitude of Photovoltaic penetration. Obviously, ESS cannot store energy in condition (1). The PV energy storage system cannot (or just happens) to supply all peak load requirements. When it is in condition (2).
In order to make the operation timing of ESS accurate, there are three types of the relationship between the capacity and load of the PV energy storage system: Power of a photovoltaic system is higher than load power. But this time, the capacity of ESS is less than or equal to the total demand capacity of the load at peak time;
