PROJECT TITLE:

Integration of Wind Power and Wave Power Generation Systems Using a DC Micro grid - 2015

ABSTRACT:

In order to check the uncertainty and intermittent characteristics of wind power and wave power, this paper proposes an integrated wind and wave power generation system fed to an ac power grid or connected with an isolated load using a dc microgrid. 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 the written program primarily based on MATLAB/Simulink. Root-loci plots of the studied system below varied speeds of the wave generator are analyzed. To examine the basic operating characteristics of the studied integrated system joined with the dc microgrid, a laboratory-scale platform is also established. Comparative simulation and experimental results reveal that the studied integrated system will maintain stable operation to provide power under totally different operating conditions using the proposed dc microgrid.
