Multiterminal HVDC System with Power Quality Enhancement

High-Voltage Direct Current (HVDC) systems are a feasible solution that allows the transmission of energy between several power networks. As consequence use HVDC systems, renewable sources can be integrated more easily into distribution grids and smart grids. Furthermore, contribute to improving quality (PQ) which they connected. This paper presents multiterminal system not only controls flows active four different networks, but also compensates imbalances harmonics in grid currents maintain balanced sinusoidal voltages at point common coupling various The compensation is carried out by voltage-source converters (VSCs) connected their respective AC A control scheme based on resonant regulators proportional–integral (PI) controllers responsible for achieving necessary flow with amelioration PQ. case study comprises terminals sharing DC bus 80 kV simulated means PSCADTM/EMTDCTM (Power System Computer-Aided Design; Electromagnetic Transients including Current), where associated suffer from voltage owing connection unbalanced loads nonlinear loads. obtained simulation results show performance complete terms flow, regulation, harmonic distortions current voltage.
