However, its solution model has limitations. It is not possible to find a completely suitable model for the optimal scheduling solution of the ice storage system. At the same time, the result obtained by the solution is only an optimal solution in the mathematical sense. In actual use, the planning results need to be calculated twice. adjustments to obtain satisfactory results

Abstract
The invention provides a dispatching method of an ice storage air conditioning system. The dispatching method comprises the steps that system real-time operation data, load prediction data, equipmentoperation maintenance plan data and system equipment parameters are obtained; the boundary condition of optimized dispatching is determined; according to the boundary condition of optimized dispatching, with the lowest system operation cost in the dispatching time period as the target, a predetermined optimized dispatching model is used for performing optimized dispatching calculation, and the hourly startup number of a base load unit and a double-working-condition unit and the hourly load of the ice melting amount are obtained; a load level in the optimization time period is determined according to an optimization dispatching result; and according to a preset equipment start-stop adjustment strategy and the determined load level, equipment start-stop time period adjustment is carried outto reduce the equipment start-stop frequency in the optimization time period. According to the dispatching method of the ice storage air conditioning system, the overall operation cost of a system onthe day can be reduced while the load requirements of each time period are met, the equipment start-stop frequency can be reduced, and system fluctuation caused by frequent equipment start-stop is avoided.
Description
technical field [0001] The invention relates to the technical field of control of an ice-storage air-conditioning system, in particular to a scheduling method for an ice-storage air-conditioning system. Background technique [0002] With the development of the national economy, the consumption of energy, especially electric energy, is increasing day by day. However, due to the habits of production and living energy consumption, there is a large difference in day and night electricity load. Now all parts of the country implement peak-valley time-sharing electricity prices to guide production and living consumption. It can be adjusted to realize peak shaving and valley filling. The ice-storage air-conditioning system can store cold during the valley period and release the cold during the peak period. While reducing the electricity cost of the system by using the difference in the peak-valley electricity price, it can also realize peak-shaving and valley-filling, which has good...
