چکیده

سیستم‌های سایبری فیزیکی به دلیل کاربردهای گسترده آن در حوزه‌های مختلف در طول دهه گذشته به توسعه سریع دست یافته‌اند و معمولاً با توانایی‌های سنجش، ارتباط، محاسبات و فعال‌سازی تشکیل‌شده‌اند. بااین‌حال، شبکه ارتباطی سیستم‌های امنیت فیزیکی ممکن است توسط حملات سایبری مورد حمله قرار گیرد که عملکرد سیستم را به طور چشمگیری از بین می‌برد. اخیراً حملات قطع سرویس DOS)) توجه زیادی را به خود جلب کرده است. در این مقاله راهکاری برای مقابله با حملات DoS به سیستم کنترل تسهیم توان شبکه توزیع انرژی الکتریکی شامل تولیدات پراکنده ارائه‌شده است. طور یکه یک تخمین‌گر توزیع‌شده متغیر با زمان بکار برده شده است. بر اساس ویژگی مدت‌زمان ارتباط قطع سرویس، شرایط طراحی همگرا پارامترهای ناظر با استفاده از تئوری انتگرال لبگ و روش میانگین زمان ماند به دست می‌آید. همچنین نشان‌داده‌شده است که خطاهای ناظر همگرا می‌شوند. درنهایت روش مقابله ارائه‌شده بر روی خط کنترل امپدانس مجازی سیستم کنترل تسهیم توان قرار گرفته و حملات قطع سرویس را خنثی خواهد کرد.

چکیده [English]

Cyberphysical systems have achieved rapid development over the past decade due to their widespread applications in various domains, and are typically composed of sensing, communication, computing, and actuation capabilities. However, the communication network of physical security systems may be attacked by cyber attacks, which significantly destroys the performance of the system. Recently, DOS denial-of-service attacks (1) have attracted a lot of attention. In this article, a solution to deal with DoS attacks on the power sharing control system of the electrical energy distribution network, including distributed generation, is presented. So that a time-varying distributed estimator has been used. Based on the feature of service interruption communication duration, the convergent design conditions of observer parameters are obtained using Lebag2 integral theory and average dwell time method. It is also shown that the observer errors converge. Finally, the presented coping method is placed on the virtual impedance control line 3 of the power sharing control system and will neutralize service interruption attacks
