Further research directions Due to the important application value of grid side energy storage power stations in power grid frequency regulation, voltage regulation, black start, accident emergency, and other aspects, attention needs to be paid to the different characteristics of energy storage when applied to the above different situations.
For each typical application scenario, evaluation indicators reflecting energy storage characteristics will be proposed to form an evaluation system that can comprehensively evaluate the operation effects of various functions of energy storage power stations in the actual operation of the power grid.
Due to factors such as high prices of energy storage devices and imperfect market models, China's grid side energy storage projects are currently in their early stages, with limited engineering applications and a lack of evaluation methods of the actual operational effectiveness of power stations from multiple perspectives.
As the proportion of renewable energy infiltrating the power grid increases, suppressing its randomness and volatility, reducing its impact on the safe operation of the power grid, and improving the level of new energy consumption are increasingly important. For these purposes, energy storage stations (ESS) are receiving increasing attention.
Evaluating the actual operation of energy storage power stations, analyzing their advantages and disadvantages during actual operation and proposing targeted improvement measures for the shortcomings play an important role in improving the actual operation effect of energy storage (Zheng et al., 2014, Chao et al., 2024, Guanyang et al., 2023).
For example, Station A has advantages over other power stations in terms of comprehensive efficiency and utilization coefficient, while it is relatively insufficient in terms of offline relative capacity, discharge relative capacity, power station energy storage loss rate, and average energy conversion efficiency.
