A Simulation Study on Coordinated Control Strategy of Micro-grid Based on DIgSILENT Platform

In order to maximize the distributed generation advantage in the economy, energy and environment, and to coordinate the contradiction between the distribution network and distributed generations at the same time, the distributed generations usually operate at the organization mode of micro-grid. In this paper, as to micro-grid system with combination of photovoltaic, wind power, storage device and adjustable load, a coordinated control strategy of the micro-grid is studied based on master-slave control. And four kinds of micro-grid operating statuses under the coordinated control strategy are simulated based on the DIgSILENT platform to verify the rationality and effectiveness of the proposed coordinated control strategy.
