Description

technical field

[0001] The invention belongs to the field of distributed systems, in particular to an energy management method of a distributed system including a heat storage device. Background technique

[0002] Distributed systems have the advantages of being close to users, good access to renewable energy, and high energy utilization efficiency, which is the development trend of new energy and renewable energy systems. Among them, the combined cooling, heating and power (CCHP) system, which uses micro-gas-fired units as the main energy supply, integrates power supply, heating, and cooling. The cascade utilization of integrated energy can reach more than 70%, so the CCHP system has become the mainstream form of distributed system development.

[0003] The CCHP system includes multi-energy input and multi-load demand, and the imbalance between production capacity and energy consumption is more prominent, and there is a common phenomenon that the system efficiency is high ...
