Abstract

This paper presents a new technique for the design of high voltage direct current (HVDC) transmission system to transmit the electrical energy generated by sustainable energy sources to load center located at far distances. The problems with high power capacity and power loss of high voltage alternating current (HVAC) system particularly in long distance transmission, has led to emerge new technology which is HVDC transmission. Therefore, with the development of high voltage valves, it is possible to transmit DC power at high voltages and over long distances. Simulation results show that the HVDC has the capability to produce ±1000 kV with high power capacity of 3 GW and efficiency equal to 98% for load center located at 1000 km. The simulation of this study is implemented using MATLAB/Simulink software. This study provides an insight and useful for the design of future HVDC transmission technology to deliver a large amount of electricity over long distance efficiently.
