Studies on the monitoring and control platform of microgrids

Energy management is one of the key spots in the research of distributed energy system. Based on the idea of centralized hierarchical control,a three layer monitoring architecture is presented. After analysis application functions of layers from monitoring system, A micro-grid integrated monitoring platform based on micro-grid CIM complies with IEC 61 970 is proposed, consisting customer interaction, energy management, system operational control, data model, etc. Finally using x20 series controllers, from B&R, developed in AS 3.08 integrated environment; the micro-grid integrated monitoring platform is built. The successful operation experience in the PV-ESS micro-grid, located in the National Solar experimental verification center, and related testing results verify the correctness of the micro-grid design of integrated monitoring platform developed control software.
