Abstract:
This paper proposes an optimal power setting method for voltage-source converter (VSC) based high voltage direct current (HVDC) system, which enables the VSC-HVDC system to dynamically select its optimal injected power to reduce the overall loading of the hybrid ac/dc systems. Based on the voltage angle controller, the gain parameter K is taken as the decision variable and the severity index is taken as the objective function for optimization of different N-1 contingencies and different load scenarios. The setting value of HVDC injected power is adjusted dynamically through the gain K in the proposed control algorithm if there is a change in the load flow due to a contingency or a change in demand. The simulation has been carried out in a modified IEEE 39-bus system, which is a hybrid ac/dc system built in MATLAB. Simulation analysis and evaluation are performed to validate the effectiveness of the proposed method and demonstrate the good performance of the strategy in alleviating the overall overload.
