Analysis of Optimal Configuration of Independent Microgrid WithElectricity-Hydrogen Energy Storage

随着微电网应用普及率逐步提升,合理配置微电网的容量对于保障系统正常运行愈发重要,为此提出了一种耦合电-氢储能的独立微电网优化配置方法。首先,分析微电网系统结构并对各设备进行建模;其次,构建以等年值总成本最小为目标的电-氢耦合独立微电网模型,并充分考虑各设备的运行约束条件;最后,通过仿真分析不同容量组合方案对系统等年值总成本的影响。仿真结果表明,当独立微电网引入蓄电池和储氢发电系统后,合理配置独立微电网容量可以提高系统经济性和供电可靠性。

With the gradual increase in the application penetration rate of microgrids,the reasonable configuration of microgrid capacity is becoming more and more important to ensure the normal operation of the system.It proposes an independent microgrid optimization configuration method coupled with electricity-hydrogen energy storage.Firstly,the microgrid system structure is analyzed and each device is modeled.Secondly,an electricity-hydrogen coupled independent microgrid model with the goal of minimizing the total cost of the same annual value is constructed,and the operating constraints of each equipment are fully considered.Finally,the impact of different capacity combination schemes on the total annual cost of the system is analyzed by simulation.The simulation results show that when the independent microgrid introduces the battery and hydrogen storage power generation system,the reasonable configuration of independent microgrid capacity can improve the economy and power supply reliability of the system.
