随着大规模分布式电源接入有源配电网，大功率输电将导致常规潮流收敛失败。全纯嵌入潮流法（HELM）在大功率输电情况下比牛顿-拉夫逊法具有更好的鲁棒性，且对初始点不敏感。目前，HELM主要是为平衡传输网络设计的。在本研究中，我们开发了一个三相HELM模型，以适应ADN的DG、三角形连接负载和ZIP负载。采用改进的不平衡IEEE 13、34、37和123测试馈线验证了所提方法在重负荷情况下的有效性和更好的性能。
With large-scale distributed generators (DGs) penetrated into the active distribution network (ADN), conventional load flow convergence failure is incurred by heavy power transmission. The Holomorphic Embedding Load Flow Method (HELM) has proven to be more robust than the Newton-Raphson method under heavy power transmission and is not sensitive to the initial points. At present, HELM is mainly designed for balanced transmission networks. In this study, we developed a three-phase HELM model to accommodate DGs, delta connection loads, and ZIP loads for ADN. The effectiveness and better performance of the proposed method under heavy load situations were validated using modified unbalanced IEEE 13, 34, 37, and 123 test feeders..
