The coordinated control of multiple energy forms, including electricity, thermal energy, and natural gas, will play a pivotal role in the evolving energy landscape. As the integration of multi-energy flows becomes increasingly essential, establishing an efficient, reliable, and flexible distributed energy grid has become a critical priority. This chapter explores the coordinated control technologies for electricity, heat, and gas, emphasizing the organic interaction and optimization of energy generation, distribution, conversion, and consumption. By analyzing the dynamic characteristics and coupling relationships of multi-energy systems, this work discusses strategies to enhance energy efficiency and economic benefits through distributed coordinated control, providing both a theoretical foundation and practical guidance for the future management of energy grids.
