基于改进凸包理论的电力系统日前经济调度
Day-ahead economic dispatch of power systems based on improved convex hull theory
摘要
Abstract
The day-ahead economic dispatch model based on standard AC power flow equation is conducive to ob-taining accurate solutions.However,it is a nonlinear programming model and has deficiencies in model convergence and computational efficiency,which limits its application in actual power systems.In this context,an economic dis-patch model based on improved convex hull theory is proposed to achieve efficient and accurate solutions.First,the day-ahead economic dispatch model based on standard AC power flow equation is introduced.Second,the convex hull theory and equation of nonlinear functions are elaborated upon,and then a day-ahead economic dispatch model based on the improved convex hull theory is proposed.Finally,the IEEE 14-bus system,the IEEE 118-bus system and an actual provincial-level power system in China are employed for simulation analysis.The simulation results il-lustrate that the proposed strategy can significantly improve the computational efficiency of the model and reduce the relaxation error,indicating its high practical application value.关键词
