An Improved OPA Model in Power System Considering Planning

摘要：

　　The power system now is a typical complex system,which has inherent characteristics of SOC.Studying on cascading failures are necessary and meaningful to insure the grids safety,national security and economic development.This paper firstly establishes the indices of power system development diagnosis,which are closely relevant to the trigger of power system evolution.Then a cascading failure model is proposed,considering planning and evolution of the power system.This model is based on OPA model,including both fast dynamics and slow dynamics.The slow dynamic process simulates the evolution of power system,which represents the functions of the planning department,while the fast dynamic process simulates power flow and cascading failures,which takes the effects of dispatch,relay protection and automation into consideration.Moreover,simulations are tested on the case of Kaifeng-Shangqiu power system in Henan Province of China,and evolution results are presented.
