将网损价格因子和网损协调系数引入目标函数,建立了改进直流潮流模型,实现了负荷在机组间的最优分配 利用交流潮流方法计算系统实际网损,并利用增量直流潮流模型将网损在机组间进行合理分摊 最后利用交直流迭代思想修正网损价格因子和网损协调系数以优化网损分配方案。IEEE14节点和IEEE118节点算例验证了该方法的可行性,算例结果充分逼近了交流最优潮流的计算结果,符合实际系统运行状况。
The net loss and net loss of coordination price factor introduced in the objective function coefficients, the establishment of an improved DC power flow model to achieve optimal distribution of load between units computing systems use the actual net loss of AC power flow method and the use of incremental DC power flow model Net loss reasonably apportioned among the crew Finally, AC-DC iteration thought the price factor correction network loss and net loss of coordination coefficients to optimize network loss allocation scheme. IEEE14 and IEEE118 node examples node to verify the feasibility of the method, numerical results approaching full AC optimal power flow calculation results, in line with the actual system operating conditions.
