Analysis of Multi-Agent-Based Adaptive Droop-Controlled AC Microgrids with PSCAD: Modeling and Simulation

A microgrid (MG) with integrated renewable energy resources can benefit both utility companies and customers. As a result, theyare attracting a great deal of attention. The control of a MG is very important for the stable operation of a MG. The droop-controlmethod is popular since it avoids circulating currents among the converters without using any critical communication between them. Traditional droop control methods have the drawback of an inherent trade-off between power sharing and voltage and frequencyregulation. An adaptive droop control method is proposed, which can operate in both the island mode and the grid-connected mode. It can also ensure smooth switching between these two modes. Furthermore, the voltage and frequency of a MG can be restored byusing the proposed droop controller. Meanwhile, the active power can be dispatched appropriately in both operating modes based onthe capacity or running cost of the Distributed Generators (DGs). The global information (such as the average voltage and outputactive power of the MG and so on) required by the proposed droop control method to restore the voltage and frequency deviationscan be acquired distributedly based on the Multi Agent System (MAS). Simulation studies in PSCAD demonstrate the effectivenessof the proposed control method.
