    this paper peresents a novel approach of fuzzy controller to stabilize the frequency in all (normal and emergency) conditions under micro grid environment. load frequency control (lfc) model plays a vital role in electric power system design and operation. from the literature, it is proven that the implementation of dr (demand response) is a key to the future micro grid. in practice, lfc-dr model is tuned by conventional controllers like pi, pd, pid controllers fixed gains. however, they are incapable of obtaining good dynamic performance over a wide range of operating conditions and load changes. this paper presents an idea of introducing a dr control loop in the traditional lfc model (called lfc-dr) using intelligent controller for a power system. dr communication delay latency in the controller design is considered and is linearized using padé approximation. the addition of dr control loop guarantees stability of the overall closed-loop system and effectively improves the system dynamic performance. simulation results show that fuzzy logic controller based lfc-dr single-area power system have better performance and superiority over a classical controller under any operating scenarios.
