主动配电网的多阶段鲁棒综合电压控制
摘要：可再生能源出力的随机性和波动性给主动配电网电压调控带来了较大的影响,本文提出了一种基于鲁棒优化的主动配电网电压调控方法,引入需求响应技术,充分利用弹性负荷的调节能力,在保证电压调控可靠的基础上优化配网运行。方法分为三个阶段:第一阶段通过不确定集的形式描述可再生能源出力的不确定性,并通过极端场景法对集合进行合理削减,将不确定性参数转化为确定性参数;第二阶段运用需求响应技术控制弹性负荷的大小,以达到对负荷削峰填谷的作用;第三阶段运用两层规划理论将可再生能源的无功容量调节与传统调压手段相配合,以减少系统网损和传统调压设备的调节次数。最后基于美国PG&E 69节点系统分析所提模型的鲁棒性、经济性、可靠性以及方法的有效性。

Abstract:As to the fact that the uncertainty and volatility of the power output of renewable sources greatly affect the voltage regulation of active distribution power network,a voltage control method of comprehensive active distribution network is presented based on robustness optimization theory by introducing demand respond technique and by using control ability of elastic load to optimize the operation of distribution power network on the base of voltage adjustment. The proposed method is completed in three phases. In the first stage, in order to determine the uncertain parameters,the uncertainty of renewable energy output is described by uncertain set, and the extreme scenario method is adopted to cut down uncertain set.In the second stage, the elastic load is applied to ease the load fluctuation by applying demand respond method.In the third stage, the DGs reactive power output actively participate in voltage control and cooperate with the traditional devices using bi-level planning to reduce the number of switching device operations and system network loss.In the end, the robustness, security and economy of the proposed model are analyzed using the PG&E 69-bus system.
