本文讨论了微电网（MG）的引入对电网的贡献如何取决于扇区耦合。MG的目的是抑制剩余需求从电网及其变化，在成本约束。在本文中，三个层次的部门耦合被认为是电力，热力和氢气的需求。在Lv.1中，MG仅根据需求提供电力。MG配备了光伏（PV）和蓄电池。在Lv.2中，MG配备了PV，蓄电池，热泵，冷水机组，热罐和氢气锅炉，以满足电力和热量的需求。供热采用热力管网敷设。在Lv.3中，所有的电力、热量和氢气供应都在MG耦合。从所得到的结果，它是肯定的，较高的部门耦合可以实现较高的灵活性，在剩余需求。
This paper discusses how the contribution of microgrid (MG) introduction to the power grid depends on sector coupling. MG is designed to suppress the residual demand from the grid and its variation, under the cost constraint. In this paper, three levels of sector coupling are considered for electricity, heat, and hydrogen demand. In Lv.1, the MG supplies only electricity to the demand. The MG is equipped with photovoltaic (PV) and storage battery. In Lv.2, the MG equipped with PV, storage battery, heat pump, chiller, thermal tank, and hydrogen gas boiler to supply both electricity and heat to demand. For heat delivery, heat pipeline network is laid and used. In Lv.3, all electricity, heat, and hydrogen supplies are coupled at MG. From the obtained results, it is ascertained that the higher sector coupling can realize the higher flexibility in residual demand.
