摘要

配电网大规模分布式光伏渗透率的不断攀升，给电网的安全稳定运行提出了更高的要求。而暂态仿真是研究电网安全稳定运行技术的重要手段，但现有暂态仿真技术难以满足含高渗透率分布式光伏电网的仿真时效性与精确性要求。鉴于此，提出一种考虑动态特性与电气距离的配电网大规模分布式光伏暂态等值建模方法。首先，基于分布式光伏短路电流响应理论分析与行业标准，提出基于机组型号和电气距离的集群划分方法，将大规模分布式光伏划分为若干子集群。其次，按照“型号一致”和“功率守恒”原则将同一子集群的分布式光伏聚合为一台等值机组。进而，通过等值无损网构造及节点消去方法，构建等值电源/负荷接入点以及配电网与上级电网公共连接点三者之间的等值网络，形成最终的等值模型。最后，基于PSASP7平台搭建仿真模型，验证所提方法的有效性。

Abstract

The ongoing rise in the penetration level of large-scale distributed photovoltaics in distribution networks has imposed higher requirements for the safe and stable operation of the power grid. Transient simulation serves as an important tool for investigating the safe and stable operational technologies of power grids. However

the current transient simulation techniques face challenges in meeting the simulation timeliness and accuracy requirements of high-penetration distributed photovoltaic power grids. In view of this

we propose a large-scale distributed photovoltaic transient equivalent modeling method for distribution networks with dynamic characteristics and electrical distance taken into account. Firstly

by analyzing the distributed photovoltaic short-circuit current response theory and industry standards

a clustering method based on unit type and electrical distance is developed to divide the large-scale distributed photovoltaics into several sub-clusters. Secondly

according to the principles of "consistent types" and "power conservation"

the distributed photovoltaics in the same sub-cluster are aggregated into an equivalent unit. Furthermore

by employing the equivalent lossless network construction method and node elimination method

an equivalent network is constructed between the equivalent power/load access points and the common coupling points between the distribution network and the higher-level power grid

thereby forming the final equivalent model. Finally

a simulation model is built on the PSASP7 platform to verify the effectiveness of the proposed method in this paper.
