Demands and challenges of energy storage
Through analysis of two case studies—a pure photovoltaic (PV) power island interconnected via a high-voltage direct current (HVDC) system, and a 100% renewable energy autonomous power supply—the
View DetailsFor 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.
Battery storage power stations are usually composed of batteries, power conversion systems (inverters), control systems and monitoring equipment. There are a variety of battery types used, including lithium-ion, lead-acid, flow cell batteries, and others, depending on factors such as energy density, cycle life, and cost.
During the three time periods of 03:00–08:00, 15:00–17:00, and 21:00–24:00, the loads are supplied by the renewable energy, and the excess renewable energy is stored in the FESPS or/and transferred to the other buses. Table 1. Energy storage power station.
To fully utilize the peak function of the energy storage power stations, constant power rate mode is used during charging and discharging, and larger power is used during discharging).
Calculation results of relative closeness. According to the evaluation values of the operational effectiveness of various energy storage power stations, station F has the highest evaluation value and station C has the lowest evaluation value.
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).
