Verification and Testing of Emergency Stability Control for Micro-Grid in Industrial Park

With the development and transformation of industrial micro-grid, analyzing the emergency stability control of micro-grid when a fault occurs and the section is disconnected is of significant importance. In this paper, the industrial power grid characteristics are analyzed and the mathematical model of comprehensive loads are established. An emergency stability controller with voltage control and frequency control functions is proposed and the block of controller is designed by the programming language DSL. A micro-grid in industrial park based on RTDS is used for semi physical simulation testing of emergency stability control strategy. Simulation of under-frequency reverse power show that the correctness and effectiveness of the emergency stability control strategy.
