摘要:为消除规模化分布式电源接入给配电网电压造成的不利影响，提出适用于主动配电系统的多目标电压调控策略。计及主动配电系统负荷的静态特性，分析不同负荷特性对主动配电系统运行的影响。进一步地，以分布式电源的有功和并网点电压等为决策对象，计及配电网安全运行约束，构建以清洁能源损失最小、电压偏移最小和网损最小为目标的电压调控模型，并采用改进的并行多目标差分进化算法对模型进行求解。以IEEE-33节点系统为例，验证所提出模型和算法的有效性，并讨论负荷静态特性对电压调控的影响。
Abstract：To mitigate the adverse effects of large-scale distributed generation on the voltage of distribution network, this paper proposes a multi-objective voltage control method under the active distribution scheme. With considering the load static characteristics of active distribution system, this paper analyzes the impact of load characteristics on the active distribution system operation. Further, this paper constructs the voltage control model to minimize the clean energy curtailment, the voltage profile derivation, and the active power losses, with taking the active power output of distribution generation and grid-connected voltage as decision-making object and considering the distribution network security operation constraint. Then, this paper uses the improved parallel multi-objective differential evolution algorithm to solve the model. Base on the simulation carried out on the modified IEEE-33 bus test system, the effectiveness of the proposed model and algorithm is demonstrated, and the impact of load static characteristics on the voltage regulation is discussed.
