Mitigation effect of flywheel energy storage on the performance of marine gas turbine DC microgrid under high-power load mutation
Due to the slow response of output power of the traditional marine micro gas turbine, the directly connecting of high-power load to a shipboard micro gas turbine power generation system usually causes large power imbalance and instability instantly. To address this issue, a flywheel energy storage s...

| description | Due to the slow response of output power of the traditional marine micro gas turbine, the directly connecting of high-power load to a shipboard micro gas turbine power generation system usually causes large power imbalance and instability instantly. To address this issue, a flywheel energy storage system (FESS) is applied to compensate the transient power changes, mitigate load fluctuations and maintain the voltage of the shipboard direct current (DC) bus. Based on a practical 100 kW micro gas turbine generator set, a detailed model of DC microgrid for the micro gas turbine generation system including micro gas turbine, FESS, synchronous generator, excitation system and load is established. The coordinated control strategy of micro gas turbine, FESS and load system is designed. The mitigation effects of FESS on marine gas turbine DC microgrid under high-power load mutation are explored by performing simulation with sudden load changes of 25%, 50% and 75% rated power and comparing the performance with and without FESS. The effectiveness of the control strategy has been verified by simulation analysis. The simulation results show that by reasonably designing the coordinated control strategy, the fluctuation of the power system can be effectively mitigated when sudden load, especially high-power sudden load is considered. The stability of the marine gas turbine microgrid has been greatly improved. |
