摘要: This paper proposes a new topology of hybrid renewable system, DFIG/PV as well storage units. PV units with are directly connected to the dc-link DFIG, which leads reducing construction cost, energy swings when wind speed changes and increasing system reliability. The proposed modeling, control strategy turbine characteristic tracking presented. introduced is designed exploit optimal operation active reactive power under different modes sub-/super-synchronous modes. performance analyzed at unit utilized active/reactive flow in dc-link. step reference fluctuations kept slight limits, multiple switching operations grid converter minimized. Finally, ensure efficiency advantages technique, full day numerical simulation case obtained MATLAB/Simulink introduced.
