Reliability assessment of cyber physical layer of smart grid network

Reliability assessment of cyber physical layer of smart grid network / Ahmad Danial Irfan Ahmad Umar
Secara umumnya, definisi grid pintar ini ialah integrasi yang membolehkan teknologi maklumat dan komunikasi (ICT) dan teknologi lain yang lebih maju bersama rangkaian kuasa berskala besar untuk membenarkan generasi tenaga elektrik, penghantaran, pengedaran, dan penggunaan untuk menjadi lebih cekap, berkesan, ekonomi, dan kelestarian alam sekitar [1]. Grid pintar adalah kombinasi sistem rangkaian fizikal yang kompleks dan sistem siber yang menghadapi banyak cabaran teknologi. Kebolehpercayaan sistem komunikasi maklumat, terutamanya komunikasi tanpa wayar adalah penting untuk memastikan operasi yang berterusan, cekap dan selamat untuk generasi grid pintar yang akan datang. Secara umumnya, penyelidikan kebolehpercayaan boleh dilakukan dari tiga peringkat, di mana setiap satu akan ditambah ke dalam kerumitan peringkat sebelumnya [2]. Daripada keputusan yang diterima, 50% tambahan penarafan talian memberi jangkaan tenaga tidak dihantar (EENS) yang lebih baik daripada 30% pertambahan penarafan talian. Lebih lagi, keputusan penilaian prestasi telah menunjukkan bahawa kegagalan peranti tanpa wayar di rangkaian grid pintar boleh mengakibatkan kos yang signifikan kepada syarikat utility. Oleh itu, kunci untuk pengoptimuman hantaran kuasa dan meminimumkan kos bekalan kuasa adalah dengan memastikan yang sistem rangkaian tanpa wayar di rangkaian grid pintar mesti mampu beroperasi dengan kegagalan sesetengah komponenya. Ini adalah untuk memastikan pengurusan sampingan permintaan (PSM) boleh dijalankan dengan jayanya. _______________________________________________________________________________________________________ Essential to the smart grid definitions is the integration of enabling information and communication technologies (ICT) and other advanced technologies with the large-scale power networks to enable electric energy generation, transmission, distribution, and usage to be more efficient, effective, economical, and environmentally sustainable [1] Smart grids are a combination of complex physical network systems and cyber systems that face many technological challenges. The reliability of data communications system, specifically wireless communication is crucial to ensure continuous, efficient, and secure operation of the next generation smart power grid. Generally, the reliability studies can be performed from three levels, in which each will add into the complexity of the previous one [2]. From the result obtained, line rating increase of 50% provides better expected energy not supply (EENS) compared to 30% increase in line rating. Moreover, the performance evaluation result has revealed that the failure of wireless devices in smart grid network can incur significant cost to the public utility. So, the key to optimizing transmission line and minimizing the cost of power supply is to make sure that the wireless network system of the smart grid network must be able to operate under the failure of some of its component. This is to make sure that the Dynamic Thermal Rating (DTR) can be implemented successfully.
