4 FAQs about Power Distribution Technical Parameters of Photovoltaic Energy Storage Cabinet
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.
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 a decision variable in a photovoltaic system?
The outer objective function is the minimum annual comprehensive cost of the user, and the decision variable is the configuration capacity of photovoltaic and energy storage; the inner objective function is the minimum daily electricity purchase cost, and the decision variable is the charging and discharging strategy of energy storage.
