Simultaneous Frequency and Voltage Control of Islanded Micro grid using Energy Storage System and Load Shedding

In this paper, the cooperative control strategy of microsources and the energy storage system (ESS) and load shedding during islanded operation is presented and evaluated by a simulation. The ESS handles the frequency and the voltage as a primary Control and in hard islanded mode, load shadding strategy added to primary control. And then, the secondary control in microgrid management system returns the current power output of the ESS into zero. The test results show that the proposed cooperative control strategy can regulate the frequency and the voltage, and the secondary control action can contribute to improve the control capability.
