Islanding operation is one of the main features of a MicroGrid (MG), which is realized regarding the presence of distributed energy resources (DERs). However, in order to deal with the control challenges, which an MG faces during island operation, particularly when the transition is associated with certain excessive load, an efficient control strategy is required. This paper introduces a Centra...

variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. this paper proposes a decentralized method that restores the frequency of a microgr...

This paper investigates the effects of knowledge-based acceleration feedback control integrated with Automatic Generation Control (AGC) to enhance the quality of frequency control of governing system. The Intelligent Acceleration Feedback Controller (IAFC) is proposed to counter the over and under frequency occurrences due to major load change in power system network. Therefore, generator tripp...

This project presents decentralized control scheme for Load-Frequency Control in Multi-area power System. In this era renewable energy is most promising solution to man’s ever increasing energy needs. But the power production by these resources cannot be controlled unlike in thermal plants. A number of optimal control techniques are adopted to implement a reliable stabilising controller. It is ...

Traditional thermal power units are continuously replaced by renewable energies, of which fluctuations and intermittence impose pressure on the frequency stability system. Electrolytic aluminum load (EAL) accounts for large amount local electric loads in some areas. The participation EAL control has huge application prospects. However, controller design is difficult due to measurement noise sys...

With the increasing penetration of renewable energy resources, power systems confront new challenges in maintaining balance and nominal frequency. This article studies load-side frequency control to handle these challenges. In particular, a fully distributed automatic load (ALC) algorithm, which only needs local measurement communication, is proposed. We prove that algorithm globally converges ...
