Outline
Carbon neutrality of Guangdong power industry is the premise and important way to achieve the overall carbon neutrality goal. Based on GD-Enduse model, with the overall goal of minimizing the cost of power system, this paper describes three carbon neutral technology paths of Guangdong power and carries out quantitative and qualitative analysis. The results show that scenario CM3 is the optimal carbon neutral technology path, and its installed capacity of renewable energy will reach 60.2% and power generation will account for 51.9%. Nuclear power will grow steadily, generating 25.0% of its electricity. The continuous decommissioning of thermal power units will reduce the number of hours of utilization of retained installed capacity and be reserved for flexible peak-trimming power supply. The carbon capture, utilization and storage (CCUS) ratio of coal and gas power will decrease to 24.0% and 44.0% respectively, while the CCUS ratio of biomass will continue to rise to 81.8%. Therefore, carbon neutrality in Guangdong’s power industry requires the large-scale intervention of CCUS technology and the rapid development of renewable energy technologies led by wind power and photovoltaic. Based on “wind, light, nuclear and storage”, employing the power structure that thermal power is used as flexible peaking power supply, and various power generation technologies and negative carbon technologies flexibly adjust complementary shortboards, can achieve the coordinated development of various types of power supplies.
