【摘要】 实际综合无功优化中,保证系统尽量远离可能的崩溃点十分重要。提出基于ε-支配域并行算法的综合无功优化模型,通过负荷裕度指标对系统电压稳定性进行评估,利用基于ε-支配域的并行计算方法,解决了单独依靠状态指标难以准确估计系统崩溃点和裕度指标应用到多目标无功优化中导致的速度瓶颈问题,实现了系统电压稳定水平的实时、全面的评估,为运行人员提供了更全面的系统信息。通过IEEE14、IEEE30和IEEE118节点系统验证了所提模型和算法的正确性和有效性。更多还原

【Abstract】 It is necessary,in reactive power optimization,to have power system to run stable and keep away from voltage collapse as possible.This paper presents a coordinated reactive power optimization model based on aε-domination parallel algorithm.It calculates load power margin by Primal-dual interior point nonlinear programming,which can assess voltage stability quickly and completely,solve the difficulty in evaluating the voltage collapse point by status indicators only,and provide operators more important information.Simulation results of IEEE 14,IEEE30 and IEEE118 node systems show that the approach is right and efficient.更多还原
