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.
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 cooperation of energy storage systems and photovoltaic power generation systems can effectively alleviate the intermittence and instability of photovoltaic output. In the selection of energy storage system components, the cycle life of lithium-ion batteries needs to be further improved.
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.
