Abstract
It is inevitable for traditional coal-burning heating approach to be replaced by cleaner means. Particularly, electric heating is being vigorously promoted in some countries including China. Due to the good complementary features between heat and electric power, electric heating load can be regarded as a dispatchable resource that improves the flexibility of power systems. This paper proposes a novel unit commitment model incorporating electric heating load as a type of demand response. The dispatch of electric heating load is optimized together with the schedule of generation units. A numerical study is carried out based on the IEEE 30 Bus system, which verifies the effectiveness of the proposed model. Results indicate that the total operation cost and carbon emission of power system can be reduced, and more wind power generation can be integrated, as a result of the optimal utilization of electric heating load demand response with this model.
