Description

technical field

[0001] The invention relates to the field of energy technology, in particular to an integrated energy micro-grid interconnection system and a dispatching method thereof, which are mainly applicable to improving the utilization level of energy efficiency. Background technique

[0002] With the development of the energy crisis, distributed energy sources such as photovoltaics and wind power have received widespread attention, but their shortcomings such as decentralization, intermittency, and volatility make them unable to be applied on a large scale. Traditionally, energy management systems such as electric energy, thermal energy, and natural gas are independent of each other. There is no interaction between various energy sources, the comprehensive utilization rate of energy is low, and energy abandonment is prone to occur. Then the concept of energy Internet was proposed. The Energy Internet is a new energy utilization system that tightly couples energy and ...
