Integrated Control Strategy of Voltage and Frequency Modulation for the Photovoltaic-storage Unit

Abstract With the increasing installation of new energy power generation, photovoltaic generation has become a significant component system. However, random and fluctuating nature can pose challenge. The combination with storage using photovoltaic-storage unit integrated machine help mitigate fluctuations output improve quality grid connection. In this paper, we propose grid-connected control strategy for machine. We use hybrid module lithium battery super capacitor as Finally, MATLAB/Simulink simulation platform to simulate verify effectiveness our proposed strategy.
