The goal and path of source network load storage coordination and interaction to help the construction of a new power system

Abstract

Under the goal of “carbon peak and carbon neutral”, the characteristics of the power system mainly based on new energy will undergo significant changes. In order to solve the problem of insufficient power supply capacity caused by the precision of new energy generation, this paper puts forward the construction scheme of the new power system of source network, load, storage coordination, and interaction, and uses energy storage and flexible load adjustment to improve the transmission capacity of the connection line under emergency conditions. At the same time, energy storage centers and load aggregation providers are used to optimize the equivalent load under normal conditions and minimize the shortage of power supply capacity. Furthermore, the mathematical model of each index is established and the coordination level of source network load storage based on AHP-Delphi empowerment is proposed. Finally, the rationality of the actual planning scheme in the province is comprehensively evaluated, which provides a reference for the construction of the new power system.
