Abstract

Abstract: Based on the analysis of microgrid developments, a stand-alone microgrid that can be applied to island, desert, remote mountain areas was built according to the theory of multi-grade structure. The topology and characteristics of this kind of microgrids were illustrated. A MW-grade and stand-alone microgrid with wind/solar/diesel/battery supplies was built for a given island. Key technologies in scheduling control strategies, such as multi-grade control methods, energy dispatching processes and multi-goal coordinated controls, were expounded. The overall structure and functions of the control system for the microgrid were validated by implementing the integration of SCADA and dispatching.
