Operational efficiency also improved, with equivalent utilization hours of approximately 1,000 hours in 2024, according to statistics from grid enterprises.
In recent years, many scholars have carried out extensive research on user side energy storage configuration and operation strategy. In and, the value of energy storage system is analyzed in three aspects: low storage and high generation arbitrage, reducing transmission congestion and delaying power grid capacity expansion.
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.
By the end of 2024, the cumulative installed and operational capacity of new energy storage projects nationwide reached 73.76 GW/168 GWh, approximately 20 times that of the end of the 13th Five-Year Plan and more than 130% higher than at the end of 2023.
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 factory parameters of energy storage refer to the data in, N 0 is set to 1591, and k p is set to 2.09. Power customers use energy storage “low storage and high release” arbitrage, and time-of-use electricity prices have a greater impact on the optimization results of energy storage operations.
