In this project, the load and/or grid linked with an inverter is made as the combination of voltage sources and current sources at harmonic wavelengths. Moreover, a droop control technique is designed for systems providing power to a continuous current source, instead of a continuous voltage source. This is then used to create a harmonic droop operator so that the right amount of harmonic voltage is added to the inverter reference voltage to make up the harmonic voltage decreased on the outcome impedance due to the harmonic current. Simulation results are offered to show that the suggested technique can considerably improve the voltage THD.Keywords

This project gives a microgrid made up of distinctive Distributed Generation (DG) models that are connected with the submission lines. A vitality administration model is connected to arrange the highlights of the distinctive DG models in the microgrid for framework associated and islanded highlights. This paper proposed microgrid have PV array as a DG unit. Since power generated by a PV array is not constant. In order to maintain stability of grid a proton exchange membrane fuel cell is used to support the grid. The outline is affirmed through different test circumstances to demonstrate the utilitarian capacity of the recommended microgrid, and the procured results are said. Kalman filters are used to extract the harmonic component of distorted source voltage and load current and to generate the necessary references for the controller. In larger power system causes steady state and transient problems. In order to conquer these problems a new Model Predictive Control (MPC) is used.Keywords
