Energy storage is a good way to solve the challenges brought by the access of high proportion of renewable energy and plays an important role in peak load regulation [6], [7], [8]. Energy storage can store the excess renewable energy while the period of load valley and release the stored energy while the period of load peak, so as

The optimal configuration of the rated capacity, rated power and daily output power is an important prerequisite for energy storage systems to participate in peak regulation on the grid side. Economic benefits are the main reason driving investment in energy storage systems. In this paper, the relationship between the economic indicators
The use of BESS to achieve energy balancing can reduce the peak-to-valley load difference and effectively relieve the peak regulation pressure of the grid [10]. Lai et al. [11] proposed a method that combines the dynamic thermal rating system with BESS to reduce system dispatch, load curtailment, and wind curtailment costs.
To date, 11 states, California, Oregon, Nevada, Illinois, Virginia, New Jersey, New York, Connecticut, Massachusetts, Maine, and Maryland, have adopted procurement targets. [8] California was the first state to adopt a procurement target and initially mandated that the state''s investor-owned utilities procure 1,325 MW of energy
Energy storage is a good way to solve the challenges brought by the access of high proportion of renewable energy and plays an important role in peak load
The pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions. With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase. Moreover, wind power, nuclear power, and other new energy
Therefore, with taking account of both total costs and peak-load regulation benefits of BESS, a benefit-evaluation model for the optimal configuration of BESS is proposed in this paper. This model
This paper discusses a simple method to perform peak load shaving through the means of energy storage systems owned by a utility. Peak load shaving, also referred to as load leveling or peak shifting, consists of the schemes used to eliminate the peaks and valleys in the load profile. This practice offers direct and indirect benefits to utilities in generation

In July 2021 China announced plans to install over 30 GW of energy storage by 2025 (excluding pumped-storage hydropower), a more than three-fold increase on its installed capacity as of 2022. The United States'' Inflation Reduction Act, passed in August 2022, includes an investment tax credit for sta nd-alone storage, which is expected to boost
Grid-level large-scale electrical energy storage (GLEES) is an essential approach for balancing the supply–demand of electricity generation, distribution, and usage. Compared with conventional energy storage methods, battery technologies are desirable energy storage devices for GLEES due to their easy modularization, rapid response,
The single peak type load curve is shown in figure 2. It can be seen that the peak-valley difference of load in this region is large and there is an urgent need for peak load regulation. According
