Akıllı şebekelerde dağıtık ekonomik dağıtımın (ED) siber güvenliği, sisteminverimli ve güvenilir çalışması için kritik bir öneme sahiptir. Özellikle, bir ajanınkendi maliyet parametrelerini manipüle ederek sistemi gizlice optimalolmayan bir duruma getirdiği sinsi saldırılar, tespitinin zorluğu nedeniyle ciddibir tehdit oluşturduğu bilinmektedir. Bu çalışma, bahsedilen sinsi maliyetparametresi saldırılarına karşı, uygulaması basit ve mimari tabanlı yeni birsavunma stratejisi sunmaktadır. Önerilen yöntem, ağa stratejik olarakyerleştirilmiş güvenilir düğümler mimarisine dayanmakta ve normaldüğümlerin, kötü niyetli ajanlardan gelen anormal verileri güvenilirkomşularından aldıkları bilgiye göre proaktif olarak filtrelemesinisağlamaktadır. Stratejinin etkinliği, MATLAB ortamında gerçekleştirilensimülasyonlarla üç farklı senaryo altında test edilmiştir. Sonuçlar, önerilensavunma mekanizmasının saldırıyı başarıyla etkisiz hale getirdiğini, sağlıklıdüğümlerin optimal konsensüse ulaşmasını sağladığını ve sistemin ekonomikkayıp yaşamasını engellediği görülmüştür.

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