Research on Carbon Emission Optimization Strategy of Regional Power Grid Based on Interior Point Optimization Algorithm

Abstract

Under the background of the national dual carbon strategy, it is very necessary for power enterprises to give full play to their subjective initiative and carry out the research on the optimization strategy of carbon emission reduction based on the allocation of existing power generation resources. Based on the full study of the relationship between power grid power flow and carbon emission, this paper puts forward the indicators such as carbon emission per kWh and electricity carbon neutralization index, constructs the regional power grid carbon emission optimization model as a link, and uses the primal dual interior point method to optimize the unit output. Taking a typical day of a regional power grid as an example, the carbon emission reduction calculation is carried out according to the two stages of unified dispatching unit optimization and self owned power plant optimization. The relevant results show that the carbon emission indicators proposed in this paper can well characterize the carbon emission level of the regional power grid, the carbon emission optimization model is accurate and reliable, and the optimization strategy results can be used as an important reference for the carbon emission reduction of power grid regulators [1].
