Problems solved by technology

Therefore, it is difficult to meet the operation guidance requirements of distributed energy stations only based on the thermal system analysis results under several typical environmental conditions, resulting in the fact that distributed energy stations cannot be guaranteed to be in the best operating state in real time during actual operation.

[0004] Compared with traditional thermal power projects, distributed energy projects have more types of equipment, and there are complementary effects between them, such as the complementarity of waste heat boilers and gas boilers in cogeneration; The complementarity between refrigerators, heat pumps, gas boilers, and direct-fired engines; the integration of various functional modules such as electric energy storage, water/ice storage, and heat storage charging and discharging strategies, has resulted in the complexity of the operation mode of distributed energy stations. sex

[0005] At present, most distributed energ...
