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.
The photovoltaic installed capacity set in the figure is 2395kW. When the energy storage capacity is 1174kW h, the user’s annual expenditure is the smallest and the economic benefit is the best. Fig. 4. The impact of energy storage capacity on annual expenditures.
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 main structure of the integrated Photovoltaic energy storage system is to connect the photovoltaic power station and the energy storage system as a whole, make the whole system work together through a certain control strategy, achieve the effect that cannot be achieved by a single system, and output the generated electricity to the power grid.
When photovoltaic penetration is between 9% and 73%, photovoltaic power generation is large and energy storage can be generated. However, under the combined action of energy storage and photovoltaic, the total peak load demand cannot be completely offset, and the peak load needs additional power purchase.
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.
