Damping Controller

This project presents the analyzed results of an integrated offshore wind and seashore wave farm fed to an onshore power grid through a unified power flow controller (UPFC) to simultaneously achieve power-fluctuation mitigation and stability improvement. A damping controller of the proposed UPFC is designed by using modal control theory to render adequate damping characteristics to the studied system. A frequency-domain scheme based on a linear system and a time-domain scheme based on a nonlinear system. From time domain analysis, the UPFC is designed. The proposed UPFC joined with the designed damping controller can effectively stabilize the studied integrated OWF and SWF under various interruption conditions. The fluctuated power injected in to the power grid can also be effectively mitigated by the proposed control scheme.
