The configuration of user-side energy storage can effectively alleviate the timing mismatch between distributed photovoltaic output and load power demand, and use the industrial user electricity price mechanis.
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.
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 optimal configuration of energy storage capacity is an important issue for large scale solar systems. a strategy for optimal allocation of energy storage is proposed in this paper. First various scenarios and their value of energy storage in PV applications are discussed. Then a double-layer decision architecture is proposed in this article.
The main structure of the integrated Photovoltaic energy storage system is to connect the photovoltaic power station and the energy storage system as a whole, make the whole system work together through a certain control strategy, achieve the effect that cannot be achieved by a single system, and output the generated electricity to the power grid.
However, considering the economy, since the storage cost is higher than the power purchase cost in the trough period, when the photovoltaic power generation storage capacity is enough to offset the demand in the peak period, it will not continue to store energy and choose to abandon the PV.

[PDF Version]The above research on combined power generation systems only stays in dispatch optimization and configuration of energy storage capacity, and does not optimize the capacity configuration of other power sources in the power generation system, nor does it consider the fluctuation of the power grid caused by load uncertainty.
To sum up, in the face of problems such as large abandoned air volume and uncertain output of traditional wind farms, there are two solutions commonly adopted by researchers. One method is to equip energy storage system on the basis of traditional wind power generation system, and build a combined operation mode of wind storage.
The capacity optimization allocation method proposed in this paper can effectively alleviate the load peak demand, improve the optimization allocation model of wind-solar combined power generation system, make the configuration results more reasonable, and improve the economy of the system. 1. Introduction
The introduction of CSP power stations in wind power generation means to improve the absorption capacity of wind power generation by means of energy complementarity and balance the output fluctuations of the system.
According to the fluctuation of wind power, the operation of the heat storage system is adjusted. When the wind power fluctuates greatly, the CSP station can use its heat storage system to convert excess electric energy into heat energy for storage.
With the goal of minimizing the investment and operation cost of composite energy storage, the authors of proposed the hybrid energy storage model of pumped storage and battery after optimization analysis, which reduced the impact of wind power on the power system and improved the penetration rate of wind power.
