Objective. In order to improve the intelligence of power grid energy dispatching, this study proposes an interactive system of power grid intelligent energy dispatch based on virtual reality technology. Through the introduction of the main functions of the intelligent energy dispatching visualization system and the analysis of the construction of software and hardware, as well as the application of the actual power energy dispatching real-time operation visualization system, the system is described in detail and applied. The application results show that since the application of the system, the accuracy rate of comprehensive intelligent early warning is 100%, the monthly availability rate is 100%, and the average processing time of single fault scanning is less than 2 s. Conclusion. The system has good application prospects and in-depth research value and provides technical support for the further development of the smart grid.
