Description

technical field [0001] The invention relates to an artificial neural network-based multi-mode heating unit load distribution optimization method, which belongs to the field of thermoelectric load prediction of thermal power heating units. Background technique [0002] At present, with the steady increase in urban heating demand year by year, the problem of insufficient heating capacity has become increasingly prominent, affecting people's livelihood security. To this end, on the one hand, power generation companies increase their heating capacity through equipment and technological transformation to meet more heating load demands; on the other hand, they participate in auxiliary services in the power market through flexible transformation, and actively respond to the power system peak-shaving compensation policies successively introduced by the state. According to the needs of different power supply loads and heating loads in different periods, how to quantify and guide the ...

Problems solved by technology

However, due to the existence of multiple heating modes, the strong coupling characteristics of heat and electricity, and the differences in unit performance and the need for deep peak regulation, it is difficult for power plants to reasonably allocate and optimize the heat and electricity loads of different units based on operating experience.

[0004] 1. A calculation method and system for dynamically predicting the peak-shaving interval of thermal power units (application publication number: CN112465662 A, application number: 202011091746.X). In this paper, a calculation method and system for dynamically predicting the peak-shaving range of thermal power units are provided, which only considers the load prediction and peak-shaving space of the power grid itself, and does not discuss the peak-shaving mechanism under the background of thermoelectric coupling in heating units;

[0005] 2. A thermal and electrical load monitoring system for heating units based on GIS meteorological information (application publication number: CN209746598 U, application number: 201920165213.8). The field of this patent is the thermal and electrical load monitoring of thermal power heating units. In this method, based on The collected GIS meteorological information is used to predict the heat load and monitor the electric load in the heating area. Based on the heat load prediction, it can guide the operator's peak-shaving ability of the power grid. This method does not predict the electric load at the same time. It is only monitoring, so it has a limited role in predicting and guiding the actual power grid peak shaving capacity
