Distributed cooling-heating load prediction system and method

Abstract

The invention relates to a distributed cooling-heating load prediction system and method. At present, the load of a distributed energy station is formed by adding present cooling and heating load to recent cooling and heating load simply, and plan of the energy station is hard to guide. In the system of the invention, a present load data module, a recent load data collection module and a forward load data collection module are all connected with a primary correction module, the primary correction module is connected with an integrated load prediction module, the integrated load prediction module is connected with a secondary correction module, the secondary correction module is connected with an integrated load design module, the integrated load design module is connected with a power device, a peak modulation device and an energy storage device, the power device is connected with a waste heat utilization device, and the power device, the peak modulation device, the energy storage device and the waste heat utilization device are all connected with a client. Thus, present, near and forward load data is corrected, a reasonable load design value is obtained, and load predication is more accurate and practical.

Description

technical field [0001] The invention belongs to the field of distributed energy, and in particular relates to a distributed cooling and heating load prediction system and a prediction method. Background technique [0002] The distributed energy system is established based on the user's cooling and heating load, and the accuracy of the cooling and heating load prediction has a significant impact on the scale of distributed construction and profitability, such as the Chinese patent application number 201620439566.9. At present, the distributed cooling and heating load forecast can be divided into current load, short-term load and long-term load on the time scale. The design load of distributed energy station is basically a simple superposition of the current cooling and heating load and the recent cooling and heating load, which is difficult to accurately guide. Planning of distributed energy stations. SUMMARY OF THE INVENTION [0003] The purpose of the present invention i...
