Microgrid modeling and simulation scenario design for power quality analysis

摘要

In this paper, an electromagnetic transient (EMT) simulation model of multi-microgrid system is established in PowerFactory software for power quality study. The system structure and basic elements in the simulation model are firstly introduced, as well as the control algorithm for distributed generations (DGs). Typical operation scenarios of microgrids are then proposed, in which power quality issues are illustrated by simulations using the EMT model. The simulation results validate the feasibility of the model and scenarios.
