We found that energy storage provides more capacity value under higher penetrations of solar PV because the solar generation shortens the duration of peak net load, allowing the energy-limited storage to better reduce the remaining peak.
Reference established a capacity allocation model that considers photovoltaic output fluctuations and the economics of energy storage users to determine the optimal energy storage capacity. However, it did not consider the optimization of battery power.
However, considering the economy, since the storage cost is higher than the power purchase cost in the trough period, when the photovoltaic power generation storage capacity is enough to offset the demand in the peak period, it will not continue to store energy and choose to abandon the PV.
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.
When used concurrently on a power system, we found that the total capacity value provided by solar PV and energy storage consistently exceeds the sum of the capacity values for the two technologies when used separately.
