Abstract

The invention is applicable to the technical field of smart energy, and provides a regional energy supply cold and hot load prediction method, which comprises the following steps: collecting load related parameters of each block in a region; selecting cold and heat load indexes of each industry state to calculate cold and heat loads of each land block; dividing energy supply partitions according to the calculated cold and heat loads of each land block; according to the determined energy supply subareas, calculating total cold and heat loads of each energy supply subarea; calculating the startenergy consumption time of the land parcel according to the collected relevant parameters of each land parcel load; predicting the annual growth condition of each block load by taking the calculated energy consumption starting time as a starting point; and performing statistics on annual load data of each energy supply partition to obtain a final cold and hot load prediction result. According to the method, the influences of parameters such as the construction progress, the service type and the use after construction are fully considered, the future load growth conditions of all land blocks and all energy supply partitions can be predicted more accurately, and the method is suitable for undeveloped land blocks and areas. The method is clear and simple in physical significance and easy to implement.

Description

technical field [0001] The invention relates to a cooling and heating load forecasting method for regional energy supply, which belongs to the technical field of smart energy. Background technique [0002] Smart energy is a new technical field, an energy form that is dominated by the energy industry, uses the Internet and modern communication technology as a means, and makes full use of technologies such as the Internet of Things, big data, and renewable energy. Smart energy includes both traditional energy and renewable energy; it includes both the energy supply side and the user side. [0003] District energy supply can be classified as a form of realization of smart energy, and its energy supply form can be one or more combinations of "electricity, heat, cold, water, and gas". For regional energy supply, the scope of energy supply is usually large, the types of buildings in the region are diverse, the construction and commissioning time of each block are significantly di...
