Abstract

Abstract: The construction of a new power system is crucial to achieving the goal of carbon peak and carbon neutrality. The flexible regulation ability of the system has become a key factor in building a new power system. The new energy storage has many advantages, and the technical economy is progressing rapidly, which will become an important support for improving the flexible adjustment ability of the system. The amount and the type of new energy storage and the way to develop new energy storage are the key research topics for the new power system to support the realization of carbon peak and carbon neutrality in the future. This paper attempts to combine the transformation path of China’s power system, the collaborative planning of flexible resources, the development of energy storage technology, and the characteristics of China’s power system. Based on the transformation path scenario, three new energy storage research schemes are proposed with full consideration of the uncertainties in the development process of coal power. The source-grid-load-storage expansion optimization model of the power system based on time series production simulation is adopted to fully describe the system characteristics of power supply, load, and grid interconnection of seven regional power grids, comprehensively consider the technical and economic characteristics of system flexible resources, and quantitatively analyze the demand potential of the seven regional power grids in China for various types of energy storage. The development path of new energy storage is proposed from the dimensions of the development task, technical and economic level, and development scale of new energy storage in terms of three stages of carbon peak, rapid emission reduction, and carbon neutrality, which provides decision-making reference for the development planning of new energy storage and the sustainable development of industry in China.

Key words: new power system, new energy storage, source-grid-load-storage collaborative planning, demand potential, development path
