Energy storage power station capacity scheme design specifications

What is the optimal capacity optimization model for energy storage system?

Subsequently, based on the optimal strategy for joint operation, with the maximization of economic benefits for energy storage system as the objective, a capacity optimization model is established. The NSGA-II algorithm is employed to determine the optimal capacity of the BESS, thereby achieving revenue maximization.

What is energy storage capacity?

The quantity of electrical energy stored in an energy storage facility plays a critical role in sustaining the operation and functionality of energy storage systems. The power capacity of a facility can be determined by considering its output/input power, conversion efficiency, and self-discharge rate.

What is the optimal capacity configuration and maximum continuous energy storage duration?

The optimal capacity configuration and maximum continuous energy storage duration are determined through computational analysis, yielding values of 30.8 MW and 4.521 h, respectively. At this configuration, the daily average revenue is 2.362 × 10 5 yuan, the initial investment cost is 1.45 × 10 9 yuan, and the payback period is 4.562 years. 1.

What is the optimal configuration for energy storage?

The optimal configuration for power and maximum continuous energy storage duration is determined to be 30.99 MW and 4.52 h, respectively. At this configuration, the average daily return is 2.362 × 10 5 yuan and the initial investment cost is 1.45 × 10 9 yuan. Fig. 20. Optimal solution selected by TOPSIS. Table 4. Optimal solution data.

What is the rated power of a storage power plant?

All the data used were collected on-site at the power plant. The BESS has a rated power of 20 MW and a rated capacity of 40 MWh. It is assumed that the initial state of charge (SOC) of the storage power plant is 0.4, with upper and lower operating SOC limits of 0.95 and 0.05, respectively.

What is the charging and discharging efficiency of a storage power plant?

The charging and discharging efficiency of the storage power plant is uniformly set at 0.95. The details are presented in Table 1. Table 1. Parameters of the battries. Using the aforementioned method, scenario reduction was performed on the on-site data from the PV system and BESS to obtain typical daily data.
