The Impact of Distributed Power Sources on The Voltage Quality of Distribution Network Power Supply

本文首先阐述了分布式电源在配电网中的接入形式,然后分析了配电网供电电压质量的指标,包括电压稳定性指标、电压偏差指标和电压谐波含量指标,为后续的影响分析提供评价指标,包括逆变器的影响、配电网拓扑结构的影响以及分布式电源容量的影响。在此基础上,建立了相应的仿真模型,通过仿真分析探讨了分布式电源对配电网供电电压质量的影响程度。

This article first elaborates on the integration forms of distributed power sources in the distribution network,and then analyzes the indicators of power supply voltage quality in the distribution network,including voltage stability indicators,voltage deviation indicators,and voltage harmonic content indicators.It provides evaluation indicators for subsequent impact analysis,including the impact of inverters,the impact of distribution network topology structure,and the impact of distributed power capacity.On this basis,a corresponding simulation model was established,and the impact of distributed power sources on the quality of power supply voltage in the distribution network was explored through simulation analysis.
