What determines the optimal configuration capacity of photovoltaic and energy storage?
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.
What is the energy storage capacity of a photovoltaic system?
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.
Why is photovoltaic energy storage important for large industrial customers?
The installation of photovoltaic energy storage systems for large industrial customers can reduce expenditures on electricity purchase and has considerable economic benefits. Different types of energy storage have different life due to diversity in their materials.
What is discarded solar PV?
Residential loads and energy storage batteries consume PV power to the most extent. If there is still remaining PV power after the energy storage is fully charged, it is considered as the discarded solar PV. When the PV output is insufficient, the energy storage battery supplies power to the residential loads.
