The most novel family of power flow algorithms is based on the Holomorphic Embedding Load-flow Method (HELM), presented a decade ago. Within that family, the Multi-Stage HELM (MSHELM) is a further step from the HELM that improves convergence properties. This paper presents a Multi-Stage HELM scheme designed to speed up the convergence of power flow equations. The convergence process is monitored by a convergence factor that allows controlling the exit criterion at each of the stages of the MSHELM. The convergence factor presented provides a continuous connection between two discrete alternatives, i.e., the original HELM model and an MSHELM model with only first-degree stages, opening the possibility of finding the optimal alternative in between. application/octet-stream en-GB Revista: IEEE Transactions on Power Systems, Periodo: 1, Volumen: online, Número: 1, Página inicial: 286, Página final: 298 Instituto de Investigación Tecnológica (IIT) A convergence control scheme for multi-stage holomorphic embedding load-flow method info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion info:eu-repo/semantics/openAccess Power flow, holomorphic embedding, convergence control.
