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).

An electrical “Grid” is a network that carries electricity from power plants to customer premises. Smart Grid is an assimilation of electrical and communication infrastructure. Smart Grid is characterized by bidirectional flow of electricity and information. Smart Grid is a complex network with hierarchical architecture. Realization of complete Smart Grid architecture necessitates diverse set of communication standards and protocols. Communication network protocols are engineered and established on the basis of layered approach. Each layer is designed to produce an explicit functionality in association with other layers. Layered approach can be modified with cross layer approach for performance enhancement. Complex and heterogeneous architecture of Smart Grid demands a deviation from primitive approach and reworking of an innovative approach. This paper describes a joint or cross layer optimization of Smart Grid home/building area network based on IEEE 802.11 standard using RIVERBED OPNET network design and simulation tool. The network performance can be improved by selecting various parameters pertaining to different layers. Simulation results are obtained for various parameters such as WLAN throughput, delay, media access delay, and retransmission attempts. The graphical results show that various parameters have divergent effects on network performance. For example, frame aggregation decreases overall delay but the network throughput is also reduced. To prevail over this effect, frame aggregation is used in combination with RTS and fragmentation mechanisms. The results show that this combination notably improves network performance. Higher value of buffer size considerably increases throughput but the delay is also greater and thus the choice of optimum value of buffer size is inevitable for network performance optimization. Parameter optimization significantly enhances the performance of a designed network. This paper is expected to serve as a comprehensive analysis and performance enhancement of communication standard suitable for Smart Grid HAN applications.
