摘要:
提出一种考虑有功削减的分布式光伏主动参与配电网长时间尺度电压优化控制策略。在光伏最大化输出有功的前提下利用光伏逆变器剩余容量完成各时段无功优化,若优化后仍有电压越限,则在静态无功优化结果的基础上优化削减光伏有功输出,释放更多无功容量用于电压优化调节,得到全网最佳电压分布。考虑到光伏和负荷出力的不确定性,利用复仿射方法建立各时段功率输出模型。采用Ybus潮流计算与线性递减权重粒子群相结合的算法对优化模型进行求解。选取IEEE33节点系统进行算例分析,算例结果验证了所提优化策略的有效性。
Abstract:
A long-term scale voltage optimization control strategy for distributed PV actively participated with distribution network considering active reduction is proposed. The residual capacity of PV inverters outside the active power is used to participate in the reactive power optimization for voltage control. If the voltage still exceeds the threshold values, the active power curtailment strategy to PVs is applied to provide more capacity for reactive power optimization and maintain the voltage in range. Considering the uncertainties of PVs and load outputs, the complex affine method is employed to establish the power output model in each time period. Combination of the Ybus power flow calculation and the linear decreasing weight particle swarm optimization is used to solve the proposed optimization model. Case studies on an IEEE 33-bus system are conducted to verify the effectiveness of the proposed optimization strategy.
