Energy Storage Converter Control Strategy Based on Micro-Grid System Research

This paper introduces the control strategy of energy storage converter in different operation modes of micro-grid system. Firstly, the energy storage converter is modeled, studied in parallel mode energy storage battery charging and discharging control strategy in dc side and ac PQ control strategy, the V/f control of energy storage converter under off-grid condition is controlled, and the overall control scheme of energy storage converter is given. Secondly, this paper presents a solution to the impact of energy storage converter in switching between different working modes. Finally, based on the Matlab/Simulink simulation model, the semi-physical real-time simulation platform based on APPSIM software has further verified the control strategy proposed in this paper.
