This paper confers the control strategies in balancing the dynamic demand (DD) considering a grid connected hybrid system using Demand side management (DSM) techniques. Power generation and energy needs of consumers will always be uneven; there exists a mismatch between two terms. The hybrid energy system (HES) that carries the best features of both conventional and non conventional energy resources supplies unstable power. This instability is due to the renewable energy system (RES) penetration which is highly intermittent and non reliable. This instability also causes phase shift in voltage and current waveforms causing reactive power penetration to the electric grid leading to voltage/frequency imbalance. By means of DSM control strategies the power in the grid is made reliable with improved quality. Using proper switching tactics with Power electronic controllers for Synchronizing devices, the lead lag active and reactive power is controlled with variable connected load. The entire creature of control is integrated with the smart meters. Modeling and simulations were done in MATLAB/Simulink. The simulations were presented to evaluate the dynamic performance of the hybrid system under proposed demand balancing methodology.
