摘要

提出一种计及不平衡接入的农村低压台区高渗透率户用光伏无功主动支撑连贯策略,不依赖于静止无功发生器（SVG）等无功调节装置,首先以单相及三相接入的户用光伏逆变器为无功主动调节对象,构建计及三相不平衡情况与昼夜光伏-负荷实时出力特性的高渗透率户用光伏精细化变权重多目标优化模型,适应台区不同工况下的控制需求;其次,进一步考虑连续时段内各逆变器调节的经济性、稳定性与计算复杂度,设计基于第三代非支配排序遗传算法（NSGA-Ⅲ）与连贯控制的台区全时段主动支撑策略,高效计算三相不对称潮流,实现更为平滑的户用光伏协同无功调节。算例结果表明,所提方法可充分挖掘高渗透率户用光伏主动支撑潜力,从已有逆变器装置本身出发提升农村低压台区综合电能质量、降低台区网损,提高配电网运行的稳定性与经济性。

Abstract

This paper proposes a coherent strategy for active reactive support of household photovoltaics with high penetration rate in rural low-voltage areas taking into account unbalanced access, and especially does not rely on reactive power adjustment devices such as SVG. Firstly, household photovoltaic inverters with single-phase and three-phase access are taken as the objects of active reactive regulation, and a high-penetration household photovoltaic refined variable weight multi-objective optimization model is constructed taking into account the three-phase imbalance and the real-time output characteristics of photovoltaic-load during the day and night to meet the control requirements under different working conditions of the area. Secondly, the economy, stability and computational complexity of the regulation of each inverter in the continuous period are further considered, and the full-time active support strategy of the area based on the third-generation non-dominated sorting genetic algorithm （NSGA-Ⅲ） and coherent control is designed to efficiently calculate the three-phase asymmetric power flow and achieve smoother household photovoltaic coordinated reactive regulation. The calculation results show that the proposed method can fully tap the active support potential of high-penetration household photovoltaics, improve the comprehensive power quality of rural low-voltage substations, reduce substation network losses, and improve the stability and economy of distribution network operation.
