Description

technical field [0001] The invention belongs to the field of microgrid technology, and more specifically relates to a method and device for capacity configuration and operation scheduling of a microgrid. Background technique [0002] In recent years, distributed power generation technology has been valued and developed all over the world. Compared with centralized power supply, distributed power supply has the advantages of environmental protection, less investment, short construction period, and nearby power supply. However, due to the randomness and volatility of the output of distributed power sources such as wind power and photovoltaics, large-scale access to the power grid will have a certain impact on the stable operation of the entire power grid system. In this context, the concept of multi-energy complementary microgrid proposes a new feasible direction for the utilization of distributed power. [0003] The multi-energy complementary microgrid is an independent uni...
