Application Analysis of Multi Energy Complementary System in Regional Energy Optimization and Scheduling: Taking the Guangdong Hong Kong Macao Greater Bay Area as An Example

Abstract

The Guangdong Hong Kong Macao Greater Bay Area, as the core economic area and energy intensive region of China, faces prominent problems such as high dependence on fossil fuels, high pressure on the consumption of renewable energy, and regional energy supply-demand imbalance. Data shows that the consumption of coal and oil products in Hong Kong accounts for 91%, while the combined consumption of coal and oil in Guangdong Province accounts for 58.5%. The consumption structure dominated by fossil fuels has not fundamentally changed. The multi energy complementary system integrates multiple energy sources such as wind power, photovoltaics, natural gas, and energy storage to achieve coordinated optimization of production and consumption, which is the key path to solving the energy dilemma. This article takes the Guangdong Hong Kong Macao Greater Bay Area as the research object, and combines green finance policies such as green credit with ESG constraints to explore the application logic and practical path of multi energy complementary systems in regional energy optimization and scheduling. By analyzing the characteristics of regional energy supply and demand and complementary needs, a scheduling mechanism that integrates green finance incentives and ESG evaluation is constructed. A multi-objective model is designed and simulated for verification, and the application effects and inspirations are summarized. Research has shown that deep integration of the three can significantly improve energy utilization efficiency, reduce carbon emissions, optimize regional energy investment structure, provide practical solutions for the low-carbon transformation of energy in the Greater Bay Area, and also provide reference for similar regions.
