Abstract

Abstract: With the increasing requirements for FM quality in power systems, more and more high-quality FM resources are participating in the FM auxiliary service market. This paper proposes a SOC control strategy based on index calculation and considering AGC power unit performance evaluation criteria. This strategy defines control strategies such as charging and discharging during idle time to keep the energy storage system SOC at 55%.This control method was first applied in a 10MW/5.6MW·h project of a power plant in Guangzhou. The application effect of the project shows that the control strategy has strong practicability and good application effect. Compared with other strategies, this control strategy increases the performance of the energy storage system by 3 to 4 times and greatly improves the economic benefits of the power plant.
