6 FAQs about [The significance of distributed photovoltaic configuration energy storage]
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.
How does distributed photovoltaic (DPV) impact the electric power distribution network?
The rapid development of distributed photovoltaic (DPV) has a great impact on the electric power distribution network . Because of the mismatch between residential load and DPV output, the distribution network faces with the risk of undervoltage in peak load period and overvoltage in the case of full photovoltaic (PV) power generation .
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 energy storage important in a photovoltaic system?
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.
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.
What is a photovoltaic capacity constraint?
(2) Photovoltaic capacity constraints (12) P L. i − P p v. i (E p v) ≥ 0 Where P L. i is the load power of the user at time i, and P p v. i (E p v) is the output at time i when the photovoltaic installed capacity is E p v. The constraint is to make the photovoltaic self-use and connect to the grid without residual power. 3.2.
