[0061] The above is the first embodiment of the day-ahead scheduling method of the integrated energy system provided by the embodiments of the application. The following is the second embodiment of the day-ahead scheduling method of the integrated energy system provided by the embodiments of the application. For details, please refer to figure 2 with image 3 .
Example
[0062] A second embodiment of a day-ahead scheduling method for an integrated energy system includes:
[0063] Step 201: Construct an output model and a daily cost model for day-ahead scheduling according to the operation status of the integrated energy park in the integrated energy system.
[0064] It is understandable that the output model includes:
[0065] 1. CHP system (cogeneration system), including gas turbine and waste heat boiler;
[0066] (1) The gas turbine output electric power model. By adding natural gas to the gas turbine, the natural gas expands after combustion to provide mechanical energy and then converts it into electrical energy. The output electric power of the gas turbine is:
[0067]
[0068] Where Is the electric power output by the CHP system at time t, Is the power generation efficiency of the CHP system, Is the energy of natural gas input to the CHP system at time t.
[0069] (2) The output heat power model of the waste heat boiler. The waste heat boiler c...
