Contact UsThe 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.
However, due to constraints such as power limits, capacity limits, and self-discharge rates, the energy storage power station cannot operate continuously but rather engages in charging and discharging activities at optimal times.
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.
The charging and discharging efficiency of the energy storage station is 95 %, with a conversion efficiency of 90.25 % for each charging and discharging cycle, resulting in a loss of 9.75 % per cycle. In real-time electricity pricing, there is a significant price difference between peak and off-peak periods.
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.
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.
