The energy storage configuration model with optimising objectives such as the fixed cost, operating cost, direct economic benefit and environmental benefit of the BESS in the life cycle of the energy is
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
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.
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.
When the electricity price is relatively high and the photovoltaic output does not meet the user’s load requirements, the energy storage releases the stored electricity to reduce the user’s electricity purchase costs.
In the default condition, without considering the cost of photovoltaic, when adding energy storage system, the cost of using energy storage system is lower than that of not adding energy storage system when adopting the control strategy mentioned in this paper.
