Reducing the current harmonics of a wind farm generation based on VSC-HVDC transmission line by shunt active power filters

Clean energy refers to forms of energy that do not produce hazardous emissions, do not harm human and ecosystem health and do not destroy the environment during extraction from the Earth. One of these clean energies is wind power. Energy generated from the power of wind uses a passive form of energy collection; the system works by the force of wind and does not need any added energy. Integration of massive amount of wind power is a major challenge to power industry. One of the big issues is how to collect the wind power and feed it into the AC grid. The HVDC technology based on voltage source converter (VSC), has recently been an area of growing interest to solve this issue. Although VSC-HVDC provides solution for the connection of wind farms to the grid, some problems occur in this method. One of them is current harmonics. This paper focuses on using shunt active power filter in order to mitigate the harmonic currents produced by HVDC converters.
