Modified Direct Current Optimal Power Flow Algorithm Based on Net Loss Equivalent Load Model
摘要
Abstract
Owing to a lot of nonlinear constraints to be dealt with,the efficiency of alternating current optimal power flow (ACOPF) algorithm is not high.Moreover,it will not converge when handling power systems with small reactance branches and heavy load buses.In contrast,direct current optimal power flow(DCOPF)can solve problems fast and handle pathological power systems but fails accuracy.In the circumstance,a modified direct current optimal power flow (MDCOPF) algorithm based on the net loss equivalent load model is proposed.First,the net loss equivalent load is used to replace the line loss and the accuracy of DCOPF is improved effectively.Then,the MDCOPF is solved by using the simplified primal-dual interior point method to improve the computational efficiency.Finally,the simulation results of IEEE 30-bus,300-bus,Polish 2736-bus, and 3120-bus test systems prove satisfactory in computational accuracy and efficiency.In addition,it has a strong computing capability for pathological power systems without the solution of the alternating current power flow.关键词
