摘要:

针对主动配电网中高峰值负荷对电压安全的影响,提出基于价格引导需求侧响应的有功-无功优化策略。首先,该策略结合多场景随机优化,提出基于非参数核密度估计和标准多元正态分布序列抽样的动态风光场景生成方法,得到典型日动态风光出力的概率集合。其次,考虑需求侧响应与电网互动以降低电网运行风险,提出基于分时电价引导用户负荷侧转移与无功补偿协同的优化策略。从多个场景概率出发,以配电网电压偏移和经济运行成本最小化构建优化目标。最后,针对该模型的复杂特征,提出多目标混合种群协同优化算法,得到最优无功补偿出力和用户侧负荷调度策略。验证结果表明,本文提出的策略能够有效降低电压越限风险,减小网损,实现配电网的安全经济运行。

Abstract:

To address the impact of peak loads on voltage security in active distribution networks, an active-reactive power optimization strategy is proposed based on price-guided demand-side response. Firstly, this strategy incorporates multi-scenario stochastic optimization and proposes a dynamic renewable scenario generation method based on nonparametric kernel density estimation and sequential sampling from standardized multivariate normal distributions, yielding a probabilistic set of typical daily wind-solar power profiles. Secondly, considering demand-side response and grid interaction to mitigate grid operational risks, this study proposes an optimization strategy coordinating time-of-use price-guided load shifting and reactive power compensation. The optimization objective is constructed based on multiple scenario probabilities to minimize voltage deviation and economic operation costs in the distribution networks. Finally, to address the complex characteristics of this model, a multi-objective hybrid multi-population collaborative optimization algorithm is proposed, yielding optimal reactive power compensation output and demand-side load scheduling strategy. Verification results show that the proposed strategy can effectively reduce the risk of voltage violations, minimize network losses, and achieve safe and economic operation of the distribution networks.

Key words: scenario analysis, demand-side response, reactive power compensation, multi-objective hybrid multi-population collaborative optimization algorithm, voltage violation
