燃料电池多能互补微网系统并网运行特性研究

Study on grid-connected operation characteristics of multi-energy complementary microgrid system based on fuel cell

搭建了一套燃料电池多能互补微网系统,并搭建了相关的能量管控平台,整套系统遵循“并网不上网”的原则。以燃料电池为主要支撑电源,锂电池补充,分六种情况,对多能互补微网系统进行了试验测试。通过断开负载以及限制源端的功率输出等方式,改变微网的运行状态,能量管控系统能够及时地按照管控逻辑自动调整运行,智能化地调控微网系统的运行,保证系统的能量平衡,为燃料电池多能互补微网系统的进一步深入研究奠定了基础。

A set of multi-energy complementary microgrid system was built based on fuel cell.The energy management and control software was developed and responsible for operating automatically.The microgrid system was grid-connected with no power injection.The fuel cell was the basic power source with the lithium battery as the electricity supplement.The experimental test was conducted at six different conditions.After changing the microgrid system operating state by switching off loads and/or limiting the power source output,the energy management and control software could adjust the operating mode immediately to maintain the microgrid system stabilization.It lays the foundation for further in-depth study of fuel cell multi-energy complementary microgrid system.
