JVC integrated supervisory control system of micro-grid

Micro-grid is a small low-voltage system composed of distributed generation, energy storage and load. Behaving as a single autonomous control unit relative to the external grid, it can operate either on or off grid, thus satisfies users´ requirements of power quality and supply security. As the core control technology of micro-grid, the integrated monitoring technology,which covers the micro-grid coordination control and energy management technology, guarantees the “autonomy” and “friendly” performance of micro-grid. The design framework of a typical micro-grid integrated supervisory control system, whose basic functions and advanced applications are briefly discussed, was introduced in this paper. On this basis, the designed CIM modeling tools for micro-grid, anti-disturbance control strategy and charge/discharge planning control strategy for energy-storage was given. The on-site operation showed that the supervisory control system could work well and meet the requirements of security operation.
