A new algorithm for PV firming using three-port micro-converter

With the demand increase for electricity, the ever-increasing awareness of environmental issues, coupled with rolling blackouts, the role of renewable energy generation will become even more significant. Instead of the traditional high-power energy storage and management system at the utility scale to implement PV firming, this paper proposes a new PV (panel-level) firming control algorithm using grid-tie three-port bidirectional converter. The topology with the control algorithm and PV intermittency data collected in real time are discussed and analyzed in MATLAB/SIMULINK. The experimental results verify the proposed PV firming algorithm.
