Assessing the Impacts of Large-scale Offshore Wind Power Integration on Carbon Emission Reduction in Guangdong Province Based on Electricity Spot Market Simulation

Decarbonizing the current power industry is essential for mitigating global warming. Based on Security-Constrained Economic Dispatch, the simplified power system model is established to evaluate the impacts of large-scale offshore wind power on carbon emission of Guangdong Province from 2019 to 2028. The simulation results show that under the scenario of offshore wind power, both the total carbon emissions and carbon emission intensity of Guangdong Province will drop; the emission reduction contribution of offshore wind power will increase every year, up to 20%. The total carbon emissions and carbon emission intensity of Class A units will remain unchanged. The relevant data of Class B units presents trend similar to that of Guangdong Province. For nodes connected with offshore wind farms, the carbon emission intensity of different nodes decreases, whereas for nodes not connected with offshore wind farms, the carbon emission intensity may increase, remain unchanged, or decrease.
