Akıllı şebekelerde dağıtık ekonomik dağıtımın (ED) siber güvenliği, sistemin
verimli ve güvenilir çalışması için kritik bir öneme sahiptir. Özellikle, bir ajanın
kendi maliyet parametrelerini manipüle ederek sistemi gizlice optimal
olmayan bir duruma getirdiği sinsi saldırılar, tespitinin zorluğu nedeniyle ciddi
bir tehdit oluşturduğu bilinmektedir. Bu çalışma, bahsedilen sinsi maliyet
parametresi saldırılarına karşı, uygulaması basit ve mimari tabanlı yeni bir
savunma stratejisi sunmaktadır. Önerilen yöntem, ağa stratejik olarak
yerleştirilmiş güvenilir düğümler mimarisine dayanmakta ve normal
düğümlerin, kötü niyetli ajanlardan gelen anormal verileri güvenilir
komşularından aldıkları bilgiye göre proaktif olarak filtrelemesini
sağlamaktadır. Stratejinin etkinliği, MATLAB ortamında gerçekleştirilen
simülasyonlarla üç farklı senaryo altında test edilmiştir. Sonuçlar, önerilen
savunma mekanizmasının saldırıyı başarıyla etkisiz hale getirdiğini, sağlıklı
düğümlerin optimal konsensüse ulaşmasını sağladığını ve sistemin ekonomik
kayıp yaşamasını engellediği görülmüştür.

Reliable Node-Based Cyber Resilient Distributed Economic Dispatch for Smart Grids

Cybersecurity of distributed economic dispatch (ED) within smart grids is
critical for the system’s efficiency and reliability. Especially stealth attacks,
where an agent secretly manipulates its own cost parameters and turns the
system into a non-optimal state, are known to pose a serious threat because of
detection difficulty. This study offers a new, architecture-based defense
strategy against the mentioned stealthy cost parameter attacks, which is easier
to implement. The proposed method is based on an architecture of where
trusted nodes are strategically placed in the network and enable normal nodes
to proactively filter abnormal data from malicious agents, based on information
received from trusted neighbors. The effectiveness of the strategy is tested
under three different scenario simulations in MATLAB. The results show that
the proposed defense mechanism successfully neutralized the attack, enables
healthy nodes to reach optimal consensus, and prevents the system suffering
economic losses.
