“…The islanded operation system is included among effective measures to minimise the effects of a blackout [26][27][28]. Islanded operation represents the separation of a part of the electricity system that operates independently of the whole system [29]. The purpose of this measure is the creation of a sufficiently functional electricity grid using local sources of electricity located in the affected region or territory or in its surroundings.…”

The reliable supply of electricity is a key commodity that affects the functioning of today’s society. The long-term disruption of these supplies has far-reaching effects that will have a significant impact on all spheres of our lives. Infrastructure will stop operating and the provided services will be limited or cease. This article focuses on a comprehensive and systematic approach to strengthening the resilience of territorial units in relation to large-scale electricity supply disruption. The main part focuses on the process model of identification and evaluation of key elements of a region that are necessary to ensure the basic needs of its population. The aim of this model is to provide the security management with an effective tool on how to define the security needs in their region and determine specific infrastructure from the security perspective. The model includes a process of determining the priorities of infrastructure in accordance with their importance in the form of a methodological framework. The result is the establishment of a list of safety-relevant objects in the region, which is a necessary prerequisite for the design of an islanded operation and other measures leading to the reduction of impacts caused by large-scale power outages.

“…The different LFC management modes are analyzed in remote operation which contains different control opportunities for the steam turbine that is remotely controlled by LFC [13]. It enlightens the changes between the centralized concept of classic LFC and the decentralized concept of conventional speed control.…”

In a unified power system the Load Frequency Control (LFC) is taken for review looking at all aspects with various optimization techniques for optimizing the parameters of PI, PID and Fuzzy controllers. The power system with multi area consists of conventional, renewable and combination of both with some energy devices like SMES, battery sources is analyzed specifically in this manuscript. The controllers are designed for a deregulated environment of a power system for LFC. The Model Predictive Control (MPC) and some other control techniques are used to control LFC under various disturbances like GRC and dead band control. For the readers ease of understanding the time response comparison graph of the controller for single and multiple areas of power system is depicted.

“…Sekhar et al have suggested a hybrid PID controller based on Firefly Algortihm (FA) for frequency control [7]. Maslo et al have investigated the strategies of active power and frequency control in the state of island operation mode for a smart grid [8]. Khooban et al have pointed out that large frequency alterations may form in case of production and demand imbalances in the smart grids and to overcome this problem, the electrical vehicle batteries can be used to feed the system.…”

Güç kalitesinin sürekliliği, günümüzün modern şebeke yapısında ve geleceğin akıllı şebeke yapısında önemlidir. Yenilenebilir enerji kaynaklarının mevcut şebeke sistemine dâhil edilmesi ve teknolojik cihazların kullanımının artması güç kalitesinin düşmesine neden olacaktır. Güç sistemi harmonikleri, güç kalitesinde düşüşe neden olan faktörlerden biri olarak nitelendirilebilir. Bu faktörün etkileri önlenmezse, güç sistemlerinin performansında ve güvenilirliğinde ekonomik kayıplara neden olacak bir düşüşe yol açacaktır. Bu çalışmada, yakın gelecekte hayatımızda çok önemli bir rol oynayacak ve muhtemelen yeni şebeke altyapısına örnek olabilecek bir mikro şebeke tasarlanmıştır. Bu mikro şebeke, PSCAD/EMTCD programı ile simule edilmiştir. Güç sistemi simülasyon programları arasında PSCAD/EMTDC programı, gelişmiş grafik olanakları ve gerçek zamanlı model uygulamaları gibi öne çıkan özelliklerinden dolayı tercih edilmiştir. Mikro şebekelerin, sistem güvenilirliğini artırmak, dağıtık üretim (DG) birimleri arasında paylaşmak ve frekans-gerilim değerlerini belirli sınırlarda tutmak için kontrol yöntemlerinin kullanması gerekmektedir. Bu çalışmada en çok kullanılan yöntemlerden biri olması ve literatürdeki başarısı kanıtlanmış olması nedeniyle droop control yöntemi tercih edilmiştir. Tasarlanan sistem dört farklı senaryo ile test edilmiş ve sonuçlar tartışılmıştır. Güç kalitesini etkileyen nedenlerden biri olan yük frekansı kontrolü (LFC) özellikle analiz edilmiştir. Tüm senaryolardan elde edilen sonuçlara göre, dört numaralı senaryo hariç, frekans aralığının 58-60 Hz bandını geçmediği belirlenmiştir. Elektrikli araçların (EV) sisteme dâhil edilmesi durumunda yeni çözüm önerileri sonucunda sağlanan ek maliyetler ve avantajlar değerlendirilmiştir. Özellikle çift yönlü enerji akış (V2G) özelliğine sahip elektrikli araçların şebekeye bağlanmaları sonucu ortaya çıkan yeni durumlar incelenmiştir.
