| Abstract: |
| A typical micro-grid including photovoltaic，wind farm，energy storage and energy management system is set，the configuration of micro-grid based on energy storage and its control are introduced，and the control function of energy storage in the islanded and grid-connected operation modes，as well as during the seamless transition between two modes is analyzed. For the energy-storage voltage-source converter based on LCL filter，a tri-loop control strategy is proposed，including converter-side inductance current loop，filter capacitor voltage loop and gird-side inductance current loop. The stability of two inner loops is maintained for the smooth transition between islanded and grid-connected operation modes. A micro-grid test platform is built to verify the effectiveness of the proposed control strategy. |
| Key words: micro-grid energy storage voltage-source converter seamless transition between islanded and grid-connected operations control |
