Abstract

Abstract: In the recent years, the problem of wind power curtailment has becoming increasingly serious in China. Hence it is urgent to improve the existing power system planning approaches. Considering the current situation that power system flexibility is not capable of meeting the requirements of wind power integration, in this paper the peak load regulation capacity constraint and regulation speed constraint are designed in power system planning model. Besides, this paper analyzes the multiple impacts of demand response on power systems and seeks the solution to incorporate them into the planning model. Then, a source-grid-load coordinated planning model is proposed, in which generation units, transmission lines and demand side resources are planned jointly. Through the case studies the effectiveness of the model is verified.

Key words: variable power source, power system flexibility, demand response, source-grid-load coordinated planning
