Research on evaluation method of coal-to-electricity project considering load access mode

Abstract

With the aggravation of air pollution, some cities in northern China have carried out the coal-to-electricity project in succession, replacing the traditional coal-fired heating with clean and pollution-free electric energy in winter heating period. In the process of project promotion, the regenerative electric boiler is widely used. In this context, this paper first analyzes the operating characteristics of regenerative electric boilers, and establishes a coal-to-electricity project evaluation model from the perspective of heating energy type conversion and distribution network construction based on optimization models that take into account different start-stop modes. And in the part of simulation examples, the actual data is used to evaluate and analyze the different load access methods, and the results verify the effectiveness of the model proposed in this paper. It can also guide the engineering practice and provide theoretical support for the introduction of DSM in the subsequent engineering.
