ABSTRACT
With the rapid development of renewable energy and the widespread application of distributed generation technologies, microgrids, as critical carriers for achieving efficient energy utilization and sustainable development, have become a research hotspot in the power system domain. This paper conducts an in-depth investigation into the key issues of microgrid operation control and energy management, aiming to enhance both the stability and economic efficiency of microgrids. Initially, the characteristics of various distributed energy resources in microgrids and their impacts on system operation are analyzed, followed by the proposal of a multi-ob jective optimization-based energy management strategy that integrates considerations of system efficiency, cost, and environmental benefits. Subsequently, by incorporating advanced prediction algorithms and adaptive control methods, a coordinated control system applicable to different operational modes is designed, effectively addressing the deficiencies of traditional control approaches in dynamic response and robustness. Experimental results demonstrate that the proposed energy management strategy significantly reduces the operational cost of microgrids while enhancing the accommodation capacity of renewable energy. Moreover, the coordinated control system exhibits superior stability during transitions between islanded and grid-connected modes. The primary innovation of this study lies in the combination of multi-ob jective optimization and intelligent control technologies, providing theoretical support and technical assurance for the efficient operation of microgrids. The research findings hold significant implications for promoting the practical application of microgrids.
