摘要

针对高比例分布式光伏接入配电台区导致的线路损耗加剧、电压越限及三相不平衡等问题，提出一种基于综合治理装置的协同优化策略。建立以治理装置运行成本、配电网损耗、电压三相不平衡度及电压偏差综合惩罚最小为目标的多台区配电网优化模型，采用对称半正定规划方法结合凸松弛技术处理非凸非线性问题，实现综合治理装置与配电台区的协同优化。经仿真验证，所提策略在保障光伏高效消纳、综合治理装置经济性最优的同时，能够显著降低配电网损耗，改善电压偏差和三相不平衡度。

Abstract

To address the problems such as increasing line losses

voltage limit violations

and three-phase unbalances caused by the integration of high-penetration distributed photovoltaic (PV) into distribution areas

this paper proposes a collaborative optimization strategy based on comprehensive control devices. By establishing a multi-area distribution network optimization model that considers the operational costs of the control devices

distribution network losses

three-phase voltage unbalance degree

and voltage deviation penalties

the strategy employs symmetric semi-definite programming (SDP) combined with convex relaxation techniques to resolve non-convex and nonlinear problems

achieving coordinated optimization of comprehensive control devices and distribution areas. Finally

simulation results verify that the proposed strategy can ensure efficient PV accommodation and optimal economic performance of the comprehensive control devices

while significantly reducing distribution network losses and improving voltage deviation and three-phase unbalance degree.
