Comprehensive energy system and operation control method thereof

Abstract

The invention discloses a comprehensive energy system and an operation control method thereof. The system comprises a control center, and a power supply subsystem, a heat supply subsystem and a cold supply subsystem which are respectively connected with the control center, the heat supply subsystem comprises a medium and low temperature heat storage tank, a high temperature heat storage tank and an electric boiler which are sequentially connected through pipelines. Wherein the high-temperature heat storage tank is used for exchanging heat with the medium-low-temperature heat storage tank; the electric boiler is used for circularly exchanging heat with the high-temperature heat storage tank; and the control center is used for determining an operation strategy of the system according to the real-time load received in each period and a preset operation control model, and periodically controlling the power supply subsystem, the heat supply subsystem and the cold supply subsystem according to the operation strategy. According to the system, the low-grade heat source recovered by the medium-low temperature heat storage tank is stored in the high-temperature heat storage tank, and the high-temperature heat storage tank is circularly heated by using the electric heating boiler, so that gradient temperature rise of low-grade heat energy is realized, and the problem that the low-grade heat source cannot be efficiently utilized due to too low temperature is solved.

Description
