With the development of the energy Internet, power communication services are heterogeneous, and different power communication services have different business priorities. The power communication services with different priorities have different requirements for network bandwidth and real-time performance. For traditional unified service, a scheduling method cannot meet these service requirements at the same time, and electric power communication network cannot guarantee the quality of service. Therefore, how to make full use of the time-varying characteristics of communication resources to meet the business needs of different priorities and achieve the goals of high resource utilization and transmission quality has become one of the urgent problems in the power communication network. For this reason, in order to adapt to the real-time congestion of the network, we have designed a packet scheduling method based on the dynamic adjustment of service priority, which dynamically adjusts the priority of the power service on the node; in addition, an evaluation method for the trust value of wireless forwarding nodes is introduced to improve the security of data transmission; and finally, we valuate the channel quality to establish a reasonable and efficient packet scheduling mechanism for services of different priorities. Simulation results show that this method improves the communication performance of high-priority services and improves the spectrum resource utilization of the entire system.

Lahirnya konsep Smart Grid tidak lepas dari issue global terkait dampak lingkungan hidup akibat penggunaan energy berbahan fosil secara massif yang semakin hari cadangan energy yang tersimpan akan habis dalam beberapa tahun kedepan dan diperlukan sumber energy baru yang terbarukan (non fosil).  Implementasi Smart Grid sudah banyak di terapkan dibeberapa negara, termasuk di Indonesia, konsep Smart Grid dan prototipe sudah diimplementasikan dibeberapa kota walau populasinya belum banyak. Pilar utama selain listrik, dalam konsep Smart Grid ini adalah komunikasi dan IT, dimana diperlukan komunikasi dua arah antar mesin dan saling terintegrasi antar grid. Pada kanvas ini diusulkan konsep MUSI (Multy Utility Service Infrastructure) sebagai media komunikasi dalam implementasi Smart Grid dengan menggunakan jenis kabel OPLC (Optical Low Composite Cable), dimana dua infrastruktur yang berbeda menjadi satu konsep. Pada pembahasan ini metode yang digunakan adalah studi literature, pengamatan dan data, ondesk survey, analisa keekonomian (techno economy) dan pengambilan kesimpulan. Hasil dari analisa finansial yang dilakukan bahwa dengan menggunakan model MUSI yang diajukan, NPV dengan MARR 20% didapatkan nilai positif, dan IRR sekitar 34%, sementara jika dilakukan dengan metode konvensional, NPV dengan MARR 20% didapatkan nilai negatif, dan IRR dibawah 0% (negatif).
