摘要

分布式电源接入系统大多通过电力电子功率变换器，会向系统注入谐波，影响电能质量。文中考虑谐波影响，提出了在满足谐波畸变约束下的分布式电源最大准入功率优化计算模型，并分析了分布式电源接入位置和接入功率对电网谐波电压、电流分布的影响。对于多个分布式电源的情况，提出了至少准入功率的双层优化模型和相应的优化问题求解算法，并结合杭州永宁变半山支线的算例，计算出了配电线路所能接入的分布式电源最大准入功率和至少准入功率。

Abstract

Distributed generation（DG） may inject harmonic current to connected distribution systems due to the power electronic converters. This paper proposes an optimization method for computing the maximum penetrating level of multiple distributed generators，taking into account of harmonic distortion constraints. It is analyzed how the location and output of distributed generators affect the penetrating level，and a bi-level optimization model is presented to accommodate this effect. Numerical algorithms are described in details in the paper，together with test results of a Hangzhou distribution network.
