Online Smart Load Shedding in Micro Grid with Presence of Wind Turbine

Authors

Abstract

The benefits of renewable energy have led to the increased penetration of Distributed Generators (DG) not only in the military sites, but have also increased the availability of continuous supply of electrical energy even in the critical conditions. During the national grid supply interruption, the stability of these systems (micro grid) is essential. In order to maintain frequency stability of these isolated micro grids, a balance between generation and consumption has to be always maintained. It is customary to use energy saving devices to maintain balance by increasing generation in the short runs, where large frequency deviation results in load shedding. In this paper use of interruptible/curtailable loads to maintain the balance is proposed. That is a specific load has been reduced to control the frequency. Simulation of the proposed method has been run on the model of a real network which has verified the results and its effectiveness.
