源荷储一体化的广义灵活电源双层统筹规划
Bi-level Optimal Planning of Generation-Load-Storage Integrated Generalized Flexibility Resource
摘要
Abstract
In power systems with high penetration renewable energy,the contradiction between the reduced conventional flexible generation resource and the increased flexibility demand is becoming increasingly serious.According to the flexibility balance principle,the concept of generalized flexibility is proposed and the bi-level optimal planning model including investment decision and production simulation verification is developed.Then the convexity of the planning model is proved and a two stage algorithm proposed based on the maximum net benefit/increment ratio.Finally,through the actual data of a large wind power base in north China,the benchmark scenario is evaluated,and the problem of system flexibility deficiency is analyzed. Meanwhile,the optimal planning for generation-load-storage source is implemented by the proposed model,and the sensitivity analysis for storage and demand response is discussed.The case study indicates that the proposed method can integrate the flexibility assessment in power system planning,which can also quickly conduct the sensitivity analysis to improve the robustness and applicability.关键词
