The evaluation of electric heating load construction based on renewable energy generation for coal-to-electricity project

In recent years, due to deteriorating environment, coal-to-electricity project has received a lot of attention. However, coal-to-electricity project is still in the early stage of development, and the relevant standards of electric heating load connecting to distribution network are not perfect. Based on the current problems of coal-to-electricity project, in order to improve renewable energy generation (REG) integration capacities in distribution network, typical construction schemes of electric heating load connecting to distribution network are put forward in this paper. Considering reliability and economic efficiency, a two-step scheme evaluation method for construction schemes is developed including a preliminary selection and a pareto-based selection, to achieve the optimal construction schemes of associated distribution network and REG integration in different scale of electric heating load. Finally, the application case of coal-to-electricity project is introduced to evaluate the typical schemes, which lays the foundation for the large-scale promotion of coal-to-electricity project.
