研究分布式光伏、燃料电池、微型燃气轮机等逆变型分布式电源对配电网综合负荷特性的影响。当逐步增大分布式电源的比例时,传统综合负荷模型(CLM)将难以准确描述该区域的综合负荷特性。基于逆变型分布式电源的共性,提出考虑逆变型分布式电源影响的广义综合负荷模型(GCLM),并通过仿真计算,验证该广义综合负荷模型在逆变型DG高渗透率情况下的有效性。
The influence of inverter-based distributed generations (DGs) such as distributed PV, fuel cells, microturbine etc. on composite load characteristics in the distribution network was studied. When gradually increasing the proportion of DGs, the composite load model (CLM) would be difficult to accurately describe the characteristics of the regional composite load. Based on the similarity of inverter-based distributed generation, a generalized composite load model (GCLM) considering the influence of DGs was proposed. And its validity under the high penetration of DGs was testified by simulation.
