Abstract
The most effective and trustworthy way to install HVDC grids across long distances is via a voltage source converter-based high voltage direct current (VSC-HVDC). A meshed HVDC transmission grid typically has significant issues managing the power flows across the lines and protecting against faults.Current flow controllers (CFCs) are required in mesh-HVDC grids because line currents between nodes must be balanced. Hybrid circuit breakers with forced commutation can protect HVDC grids against dc faults, but the present dc breakersfault clearing periods are too slow or unreliable to provide adequate protection against de faults on multiterminal networks. CFCs are used in conjunction with a hybrid dc circuit breaker to address these issues. The CFC's control effectiveness and design will be examined by Simulink in MATLAB. The two cases are examined, comprise a combined system made up of CFC and Circuit Breakers (CBs) and the distinct design contains CFC and CB, which are contrasted individually, Therefore, power losses can be minimized.
