Research on Multi-dimensional Comprehensive Evaluation System of Planning Schemes Based on Source-grid-Load-storage Operation Optimization

High proportion of new energy access will be one of the important directions of future power system development. In order to cope with the uncertainty caused by high proportion of new energy and improve the regulation ability of power system, resource planning should be carried out on each side of source-grid-load-storage. On this basis, for different planning schemes, a comprehensive evaluation system is urgently needed to comprehensively evaluate the planning schemes. Aiming at the economy, environmental protection, flexibility, adequacy and other indicators of power system planning, this paper proposes a multi-dimensional comprehensive rating system for power system. The improved IEEE-24 node system is used to verify the evaluation system.
