A Novel Fuzzy Cooperative Frequency Control Method for Islanding Microgrids comprising Renewable Energy Resources

Abstract

In this study a novel fuzzy cooperative frequency control method for islanding microgrids containing renewable energy resources is proposed. Frequency control, which comes from power balancing between generation and consumption components, plays an essential role to maintain the system stability. Frequency diversion is a result of a change in the microgrid. The best way to provide the balance is applying an energy storage system like a battery which could inject or take out the power from the system, immediately. In order to achieve the acceptable results, it is necessary to use the proper frequency control method which could guarantee the frequency stabilizing. The performance of the new approach is evaluated via two scenarios. Simulation results show that microgrid can be reached to the nominal frequency, efficiently.
