## 1 Introduction  
The escalating demand for electricity in our society has led to a significant surge in pressure on the power supply, causing the expansion of both the scale of the power grids and the number of substations of the power grid, thus imposing greater demands on communication quality. The prevailing wired data communication method in contemporary power systems is optical fiber communication [1], with wireless alternatives encompass-power wireless private network and power wireless public network communication. Optical fiber communication is susceptible to natural disasters and human activities, and installing optical cables in remote mountainous regions is challenging [2]. Although wireless public network communication and other wireless data communication methods offer high bandwidth, low latency, and extensive coverage communication network services to the power system, most current power communication technologies depend on infrastructure such as base stations for information exchange. However, geographical constraints and construction costs make it difficult to expand the ground communication infrastructure in remote mountain and desert regions [3]. Due to the incomplete coverage and unstable communication quality of power wireless private networks and public networks, many transmission lines in certain areas may be located in communication blind spots, leading to insufficient communication services. Furthermore, significant natural disasters can severely damage ground communication facilities, disrupting the transmission of essential information. Consequently, the inability to monitor the real-time conditions of power lines presents significant safety risks [4]. The large-scale power generation, the distribution process of the grid, and the long-distance transmission work process must ensure the safe operation of the power business [5]. This poses a significant challenge to the safe operation of the smart grid, because mainstream power communication methods cannot guarantee the reliability and security of the power business in specific power scenarios. Therefore, traditional mainstream power communication methods cannot ensure stable signal coverage, making it difficult to achieve high-quality communication in remote areas with complex terrain and vulnerability to natural disasters. These methods are inadequate for addressing current challenges faced by power communication enterprises, and fail to meet the industry's service requirements. With the increasing interconnection of power grids, satellite communications have been extensively adopted in the electric power systems sector, assuming a progressively pivotal role. As an essential supplement to electric power data communication methods, satellite communications effectively overcome the deficiencies of traditional mainstream electric power communications. Satellite communication technology can extend the coverage of traditional mainstream communication of electric power to remote areas such as oceans and deserts due to its features of high reliability, global communication coverage, and independence from harsh environmental conditions [6]. This technology enables the transmission of electricity in remote areas [7], ensuring continuous communication services. In power emergency scenarios, ensuring emergency protection, seamless communication, timely warnings, and post-disaster recovery are critical issues for power communication enterprises. The satellite communication network provides a range of services, such as data, voice, and video, to the power emergency command center, enabling real-time information exchange between disaster-stricken areas and the command center. This offers essential solutions for emergency communication [8]. Additionally, satellite communications can effectively offload terrestrial traffic to alleviate congestion in terrestrial networks, particularly when the traffic exceeds the capacity of the terrestrial link [9].
