With the advancement in modern power grid dispatching and control systems, many human–machine cloud terminals need to be equipped with applications, but the present demand is hardly met because the application management is facing such problems as low automation in the release, upgrade, and maintenance of applications, the lack of information feedback loops after software deployment, and high cost of later maintenance. In addition, cross-regional distribution is another problem in transmission due to the partition of the network in the power grid system. User experience is largely worsened by the tardy uploading and downloading of large files. To solve this problem, this study proposes a design scheme for the application store of power grid dispatching and control systems, which is mainly used for more automatic release, upgrade, and maintenance of applications as well as faster and smoother network transmission in application distribution. In this way, the quality and usability of applications are improved. Besides, information such as user behavior can be analyzed to make recommendations. The application store is capable of both life cycle management and tracking analysis of applications.
