Transmission using high voltage direct current (HVDC) is more efficient than high voltage alternative current (HVAC) for transporting higher voltage electric power generated by renewable sources (such as solar or wind power). The wind power can be integrated into the current power grid on a large scale. The purpose of this paper is to provide an overview of ways in which HVDC and wind systems can be integrated. HVDC bipolar links are examined in relation to the penetration of renewable energy. Simulating different transmission line lengths is done using MATLAB/SIMULINK. Simulations indicate that the HVDC system has lower power losses and short circuit levels than the HVAC system. Further, the simulation studies are compared with the real-time data between Pugalur AC Grid and Thrissur AC Grid. During wind energy penetration into utility networks, the comparison studiesresults in necessity to move towards HVDC technology
