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.
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.
Specifically, the energy storage power is 11.18 kW, the energy storage capacity is 13.01 kWh, the installed photovoltaic power is 2789.3 kW, the annual photovoltaic power generation hours are 2552.3 h, and the daily electricity purchase cost of the PV-storage combined system is 11.77 $. 3.3.2. Analysis of the influence of income type on economy
The PV energy storage system cannot (or just happens) to supply all peak load requirements. When it is in condition (2). The PV energy storage system is in a position to supply all peak load demands with a surplus in condition (3). These three relationships directly affect the action strategy of the ESS.
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;
According to the capacity configuration model in Section 2.2, Photovoltaic penetration and the energy storage configuration are nonlinear. Considering the charging power and other effects, if you use mathematical methods such as enumeration, the calculation is complicated and the efficiency is extremely low.
