Abstract:

Under the "dual carbon" target, it is necessary to vigorously develop clean energy and keep the guarantee role of thermal power. In order to adapt the market mechanism on both source and load end to the peak-load shaving requirements of the power grid with high permeability of renewable energy,a multi-source deep peak regulation (DPR) model with the participation of wind power,thermal power,storage and carbon capture units is proposed based on priced-based demand response(PBDR),and the characteristics of the demand response mechanism are analysed. The model not only solves the excessive energy loss, high cost, high carbon emissions and lack of motivation in participating in DPR of thermal power units, but also optimizes their output and load curves, working well on peak-load shifting, peak regulation cost reduction and pressure alleviation. Numerical study examples show that the proposed model is effective in improving wind power consumption, and reducing the coal consumption, operation cost and deep peak regulation times of thermal power units. Carbon capture units can further reduce the carbon emissions and facilitate energy storage units' earnings from participation in DPR. The pricing strategy considering the cost characteristics of thermal-storage units realizes the economic and low-carbon DRP of power grid.
