Abstract

Now a days renewable energy is widely used such as wind energy and solar energy, due to their extreme abundance. So they should be properly interfaced with the power grid with suitable devices. In this paper a system of offshore wind with low-frequency ac (LFAC) transmission system which increases the power capacity and transmission distance is proposed along with a photovoltaic integration on the offshore itself results more stability in the power system. A cycloconverter is designed for the low frequency transmission and also to interface with the main power grid. The wind power plant collection system is dc based, and connects to the LFAC transmission line with a 12-pulse thyristor converter. Simulation results are observed to analysis the output voltages and currents of the two renewable sources and to illustrate the performance of the system.
