Abstract: The traditional energy management system exhibits intricate hardware components, high equipment access cost, limited scalability and generality, making it challenging to meet the requirements of multi-function autonomous management and control in small-and medium-sized emerging scenarios. Therefore, an embedded energy management system is proposed. First, leveraging the hybrid control theory, the control configuration technology is introduced to achieve a comprehensive strategy development.Secondly, an edge optimization solver based on automatic differentiation is developed while constructing a lightweight Web application by integrating embedded database and asynchronous non-blocking communication technology. Finally, a semi-physical simulation test combined with Simulink is conducted to validate the effectiveness of the control approach. The embedded energy management system proposed in this paper has been successfully deployed at Century Substation of Hangzhou Asian Games Village of China as well as several industrial parks, resulting in significantly reducing the delivery cycle and deployment cost by over 50%, along with excellent performance.
