Instantaneous Reactive Power Theory Based Shunt Active Power Filter in Fuel Cell Micro Grid For Harmonic Reduction

To meet the demand of quality power, design of reliable power filter is highly essential. The harmonics in current and voltage is one of the challenging power quality problems and its elimination is a major requirement. The design of a shunt active power filter, SAPF for a micro grid MG based on PV and fuel cell is focused to reduce the harmonic effect in this paper. Here a PI controller is applied to regulate the filter dc voltage. The reference current is generated by the use of instantaneous reactive power theory. The craziness PSO is used to obtain the optimized PI controller gains. The detailed micro grid structure is developed and simulated with a balanced R-L and nonlinear load. The simulation result depicted that the total harmonic distortion is minimized.
