Micro-grids are usually found in two types including network connected and network independent. A micro-grid’s suitable performance is in debt of existence of an efficient control system since the issue of stability is considered as a crucial parameter in terms of energy management and planning in grids and micro-grids. An important component in terms of controlling micro-grids in network independent mode is micro-grid’s voltage and frequency controlling. There are several strategies for doing so but the most important one is the droop method. The present study tries to benefit from a PID fuzzy controller for optimal management of behavior of the backup control system aimed at controlling the micro-grid during fault condition. Data analyses and related simulations have been performed using the matlab Software. Results regarding the PID fuzzy controller revealed a higher precision and speed in terms of neutralization of the fault compared to previous methods. The proposed controller overcomes the complexities of previous methods such as using a decision making tree. In fact the proposed controller is simpler than previous ones but yet more precise and faster. ER -
