Embodiment Construction
[0074] The specific implementation manner of the present invention will be described below in conjunction with the accompanying drawings.
[0075] Please refer to figure 1 As shown, a combined cooling and power dispatching system including a back pressure cogeneration unit of the present invention includes:
[0076] A back pressure combined heat and power unit A for generating electricity and hot water;
[0077] The centralized heat absorption refrigerator is connected to the hot water outlet of the back pressure cogeneration unit A, and converts the hot water into cold water, which is passed into the pipeline 114;
[0078] The air conditioner 108 connected in parallel with the back pressure cogeneration unit A through the power cable 113, the air conditioner 108 is driven by the electric energy generated by the back pressure cogeneration unit A to generate cooling air;
[0079] The user's non-refrigeration electricity meter is used to detect the user's non-refrigeration pow...

The invention discloses a cold and electricity joint scheduling system with a backpressure type cogeneration unit and a scheduling method thereof. The system comprises a backpressure type cogeneration unit, a centralized heat absorption refrigerator, an air conditioner, an electric energy meter, a refrigerating fan coil, a cold consumption meter, a second remote centralized controller used for collecting the electric power consumption data detected by the electric energy meter and the refrigerating cold consumption data detected by the cold consumption meter, and a scheduling control device which controls the operations of the backpressure type cogeneration unit, the air conditioner and the refrigerating fan coil through a first remote centralized controller and the second remote centralized controller. By acquiring the pipeline distance between the user and the cold source and makes use of the pipeline distance to reasonably schedule the backpressure type cogeneration unit, and thereby, the error between the load value actually needed and the predicted electric load value is greatly reduced, which is good for the running and programming of the system and good for reducing the scheduling difficulty.
Description
technical field [0001] The invention relates to an urban comprehensive energy supply system, in particular to a combined cooling and power dispatching system and method including a back pressure cogeneration unit. Background technique [0002] Power load forecasting is an important part of power system planning and the basis of power system economic operation, which is extremely important to power system planning and operation. [0003] Power load forecasting includes two meanings, that is, it is used to refer to various electrical equipment installed at users such as state agencies, enterprises, and residents, and it can also be used to describe the value of the electric power consumed by the above electrical equipment. [0004] Power load forecasting is a series of forecasting work on power load. From the perspective of forecasting objects, electric load forecasting includes forecasting of future demand for electricity (power), forecasting of future electricity consumptio...
