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.
Wang and Luo (2018) find that not only holistic overcapacity but also structural overcapacity exists in the PV industry, indicating that capacity in high-end industries is insufficient and excessive in mid- to low-end industries. Overcapacity can hinder the orderly development of renewable energy (Río and Janeiro, 2016).
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.
Guided by local governments, which excessively pursued for local GDP growth, the polycrystalline silicon and solar PV cell manufacturers spared no efforts to expand production, while many enterprises in other industries also entered in this field. Then, serious overcapacity began.
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.
According to , if the PV power is limited to 30%, only 2/3 of the generated energy can be injected into the grid or used by the consumer for the cases without ESS. The same study stated that determining ESS size according to the energy consumption is more accurate than the PV power.
