Abstract: Deploying a unified security supervision platform for real-time monitoring of photovoltaic areas can quickly solve and handle various emergencies, which plays an important role in protecting the security of photovoltaic areas. However, the network resources that video transmission relies on, such as bandwidth and transmission power, are becoming increasingly scarce. Therefore, strategies such as on-demand differentiated access to resources can maximize the utilization of network resources. This paper proposes a differentiated access resource allocation strategy for large bandwidth services in photovoltaic scenarios based on Stackelberg game theory. Monitoring devices provide video content, aggregator cloud platforms provide network resources such as bandwidth and transmission power, and the power grid provides returns. Firstly, a game model among the three parties is established, with the power grid pricing based on the video quality corresponding to different video compression modes, and offering higher rewards for high-quality videos. Then, by solving the Stackelberg game, the optimal trading power and optimal trading price are obtained, enabling the participating power grids, aggregator cloud platforms, and monitoring devices to achieve maximum utility. Simulation shows that the proposed scheme has significant improvements in utility compared to uncompressed and compressed uniform pricing schemes.
