ABSTRACT
With the increasing prominence of energy crises and environmental issues, smart grids have emerged as a critical development direction for modern power systems, providing essential support for efficient, reliable, and sustainable energy management. As a core component of smart grids, user-side energy management systems (UES-EMS) play a significant role in optimizing energy utilization efficiency, reducing electricity costs, and facilitating the integration of renewable energy sources. This study aims to design an intelligent energy management system tailored for the user side to meet diverse energy demands and enhance overall system performance. To achieve this, a multi-ob jective optimization algorithm-based energy scheduling strategy is proposed, integrating real-time pricing mechanisms with distributed energy forecasting models to realize collaborative optimization management of user loads, energy storage devices, and renewable energy generation. By constructing a virtual power plant fr amework, the system can flexibly respond to grid dispatching instructions while maximizing economic benefits under the premise of ensuring user comfort. Experimental results demonstrate that the proposed system can significantly reduce users' comprehensive electricity costs across different scenarios while increasing the proportion of renewable energy consumption. Additionally, this research develops an adaptive learning mechanism for dynamically adjusting optimization parameters, further enhancing the system's robustness and adaptability.
