In order to improve the visual operation and maintenance management capabilities of the smart distribution network in mega cities, a visual operation and maintenance application system for the smart distribution network in mega cities based on integrated energy co-supply micro-grid control and operation and maintenance scheduling is proposed.Through big data analysis, the visualized operation and maintenance parameter analysis model of the distribution network is constructed, and the game equilibrium method between the refined distribution network and the microgrid is adopted.Under the general management function requirements, the distribution network game equilibrium scheduling model is constructed.Modeling and joint correlation analysis methods are used to obtain the visual control optimization model of the distribution network, combined with the segmented sample regression analysis to optimize the control of the distribution network operation and maintenance management, thereby improving the visual operation and maintenance management of the smart distribution network of the mega city and comprehensive scheduling capabilities.The simulation results show that using this method for visualized operation and maintenance management of smart distribution networks in mega cities has high reliability, good balance, and good operation and maintenance management and comprehensive scheduling performance.
