Abstract
This paper focuses on the operation control of microgrid. First of all, the definition, characteristics and operation control principles of microgrid are summarized, and it is clear that microgrid, as an important platform for the integration and utilization of distributed energy, is flexible, efficient and reliable. Subsequently, the key equipment in the operation of the microgrid is introduced, including the inverter, controller and energy storage systems, which play a core role in the energy conversion, distribution and storage of the microgrid. This paper further analyzes the difficulties in the implementation process of microgrid operation control, including equipment failure, challenges of system expansion and upgrading, renewable energy output prediction error, and load demand fluctuation. In view of these difficulties, this paper explores a series of optimization strategies, including the use of fault warning system to find potential problems in advance, promoting the intelligent upgrade of microgrid to improve the adaptive ability of the system, using advanced algorithms to improve the prediction accuracy of renewable energy outputs, and establishing an accurate load prediction model to deal with load fluctuations. This study aims to provide theoretical support and practical guidance for the safe, stable and efficient operation of microgrid by deeply analyzing the difficulties and proposing effective optimization strategies.
