A Scheduling Model for Wind Power Consumption Considering Source-Charge Coordination of Combined Heat and Power System in Low-Carbon Environment

Increasing the penetration and consumption rate of new energy sources will help reduce or control carbon dioxide emissions and better promote green and low-carbon development. Based on the establishment of deep peak-load regulation model of pure condensing thermal power units, the model for the expansion of combined heat and power plant adjustment range, interruptible electro-thermal flexible load model and combined heat and power units carbon emission model, this paper introduces a quota-based carbon emission trading mechanism and constructs a source-load coordination scheduling model of combined heat and power system that considers the characteristics of heating network and aims at minimizing the total cost of units operation and carbon emission trading. The total coal consumption and wind curtailment absorption effect in three cases are compared by cases study. The outcomes display that the model in this paper can coordinate the scheduling resources on both sides of source and load, further diminish the total coal consumption and improve wind power consumption capacity based on improving the flexibility of source and load side, and achieve wind power consumption in low-carbon environment.
