摘要：
On the one hand, industrial users such as cement plants have high emission attributes. On the other hand, they also have considerable demand response potential, which can be used as one of the important means for the power system to deal with the uncertainty of renewable energy power generation such as wind power. Therefore, in the environmental economic dispatch of power system containing wind power, this paper fully considers the emission characteristics of air pollutants and carbon of cement plants and their demand response ability, so as to realize the green and low-carbon operation of source-load coordination in the power system. First, the emission characteristics of air pollutants from thermal power units on the source side and cement plants on the load side are analyzed. Taking into account the spatial-temporal distribution characteristics of air pollutants and the environmental capacity margin of the area near the pollution source, the calculation model of environmental protection cost of thermal power units and cement plants is proposed. At the same time, the carbon emission characteristics of thermal power units and cement plants are considered, and the stepped carbon emission cost model is used to calculate the carbon emission cost of thermal power units and cement plants. On this basis, the load optimization model of the cement plant is proposed, cement plants are mobilized to participate in the demand response by means of stepped time-of-use price, and the environmental economic dispatch model of the power system containing wind power with source-load coordination is constructed. Finally, an example analysis is carried out based on the modified IEEE 39-bus system. The results show that the proposed model can not only realize the win-win situation of reducing the costs of both power grid side and cement plants, but also reduce the overall carbon emission of source and load in the power system. © 2023 Automation of Electric Power Systems Press.
