An equivalent continuous-time state-space model for VSC-HVDC in the synchronous dq reference frame has been established in the paper. Based on the model, relevant control strategies have been developed for the cases of supplying active and passive systems. The multi-input multi-output (MIMO) control schemes are emphasized in designing power controller and voltage controller. The scheme features feed...
Through the analysis on voltage source converter (VSC) equations in dq0 coordinate system, the state space equation of the generalized plant is gained. By use of Hinfin theory, constant DC voltage Hinfin controller and constant AC voltage controller are designed. On the basis of establishing MATLAB simulation model for transmitting power to passive network via VSC-HVDC system, the simulation of control...
With increasing attention to sustainable development and environmental protection, more and more countries turn to wind energy to reduce their dependence on traditional fossil fuel energy. Among the new challenges with this trend is how to integrate wind farm with existing AC network more effectively. The paper presents a possible measure based on VSC-HVDC, namely so-called wind farm incorporated...
