新型电力系统下抽水蓄能和新型储能协同运行研究OA

In order to promote the construction and development of the new power system and enhance the regulation and storage energy ability of the new power system,this paper explores the support of pumped storage and new energy storage coordinated opera-tion for different regulation demand scenarios of the new power system from the perspective of scheduling operation.Firstly,based on the operational characteristics of pumped storage and new energy storage,the collaborative operation mode is analyzed.Then,the pumped storage and new energy storage collaborative optimization scheduling model is constructed,and 7 types of energy storage ap-plication scenarios are constructed based on typical power consumption characteristics and extreme meteorological characteristics.Finally,the system operation effects of the power system under different energy storage development strategies are evaluated from four aspects:calming new energy fluctuations,promoting new energy consumption,enhancing power supply reliability and alleviating system peak load pressure.The results show that when the system is deployed with pumped storage and new energy storage at the same time,the system has better comprehensive operation benefits.The research can provide reference for the rational adjustment of energy storage dispatching operation modes in different regulation demand scenarios of the new power system.
