Construction and Example Analysis of a Comprehensive Value Measurement Model for Energy Storage in a New Power System

Based on the externality theory, the paper analyzes the comprehensive value mechanism of energy storage allocation in the new power system, considers multiple random disturbances, constructs a comprehensive value measurement model from the perspective of economic benefits and system safety, measures the comprehensive value and safety performance of energy storage in the new power system, and verifies the scientificity of theoretical research by analyzing numerical examples. The research results indicate that energy storage has greater comprehensive value in the context of a high proportion of renewable energy in the new power system. Combined with the output curve of traditional coal-fired units, the integration of energy storage systems significantly reduces the peak load borne by traditional coal-fired units, reduces peak valley differences, and enables traditional coal-fired units to operate more economically and efficiently, thereby reducing unit coal consumption. The paper provides a scientific measurement method for comprehensively and objectively understanding the application potential and value of energy storage, and helps the healthy and sustainable development of the energy storage industry.
