Integration of Wind and Wave Power Generation to a DC Micro Grid Using Fuzzy Controller

Abstract

This paper presents analysis of power flow management in wind power and wave power. This paper proposed an integrated wind and wave power generation system fed to an ac power grid or connected with an isolated load using a dc microgrid using FUZZY controller. The proposed dc microgrid connects with a wind power generator through a voltage -source converter (VSC), a wave power generator through a VSC, an energy storage battery through a bidirectional dc/dc converter, a resistive dc load through a load dc/dc converter, and an ac power grid through a bidirectional grid - tied inverter. The studied integrated wind and wave system joined with the dc microgrid is modeled and simulated using MATLAB/Simulink model design reveals that the proposed integrated control system can maintain stable operation to supply power under different operating conditions using the proposed dc microgrid by varying duty ratios of individual converter and pitch angle of wind system is shown.
