Key technology of scalable SCADA system for microgrids

A scalable SCADA system model was built in order to break through the limitations of traditional SCADA system for microgrids including the closed system structure and the lack of continuous development. The scalable SCADA system which meets the monitoring and calculation needs of various new energy components, can be promoted rapidlys and provide support for application and extension of multiple operation control strategies for microgrids. Based on service-oriented architecture (SOA), the encapsulation and extension of the modularized functions were realized. The integrated modeling maintenance scheme was proposed, and the equipment-oriented and model-oriented intelligent calculation and control methods were provided. Through reconfiguration of the traditional SCADA services based on SOA technology, a SCADA platform with strong adaptability and multi-dimensional extensibility for microgrids was set up. The connectivity, flexibility, and diversity of SCADA technologies were promoted so that the system can be used in different forms of microgrids. The application effects of the interconnection and extension of the system were demonstrated by the engineering project of Nandu energy-storage power station.
