In this work, novel stability results for load frequency control (LFC) system considering time-varying delays, nonlinearly perturbed load, and disturbance of parameters are proposed by using proportional-integral strategy. Considering the exogenous disturbance, an improved criterion in form linear matrix inequalities (LMIs) is derived simple Lyapunov–Krasovskii functionals (LKFs). The delay-dep...

Recently, a new Emergency Control Centre for Albanian Transmission System Operator (TSO), which includes Supervisory control and data acquisition (SCADA) Automatic Generation (AGC) applications, has been commissioned. Nowadays, an AGC application is being prepared the biggest generation company in Croatia, as part of centre hydropower plants within western Croatia. Both these implementations us...

This work presents a methodology for optimal parameter tuning of PID controller for frequency regulation in PV-Diesel two area power system. The gains of PV generator and diesel generator are optimized in a coordinated manner by employing biologically inspired optimized algorithms like Bat Algorithm (BA) and Firefly Algorithm (FA). Transfer function model of the diesel generator is interfaced w...

This paper describes an application of Artificial Neural Networks (ANN) to Load Frequency Control (LFC) of nonlinear power systems. Power systems, such as other industrial processes, have parametric uncertainties that for controller design had to take the uncertainties into account. For this reason, in the design of LFC controller the idea of robust control theories are being used. To improve t...

In industry or any area increasing load is a vast problem for power generation plants due to increase in demand for power. So making balance between generation and demand is the operating principle of load frequency control (LFC). The reliable operation of a large interconnected power system necessarily requires an Automatic Generation Control (AGC). The objective of AGC is to regulate the powe...

In this paper, we propose a unified probabilistic decentralised control and message passing framework for real time of the electrical grid which enables development future smart grid.

Within framework, electric is decomposed into...

A novel design of a robust decentralized load frequency control (LFC) algorithm is proposed for an inter-connected three-area power system, for the purpose of regulating area control error (ACE) in the presence of system uncertainties and external disturbances. The design is based on the concept of active disturbance rejection control (ADRC). Estimating and mitigating the total effect of variou...

This paper aims at investigating the problem of Load Frequency Control (LFC) in interconnected power systems in order to obtain robustness against uncertainties. A design method for a robust controller, based on Quantitative Feedback Theory (QFT), has been presented in this paper. For a two-area power system, the simulation results show that the system response with the proposed QFT controller ...

The reliability of a power system depends on its ability to handle fluctuations and varying load demands, as uncontrolled frequency deviations can lead load-shedding blackouts. Optimally tuned controllers are essential for Load Frequency Control (LFC) applications efficiently stabilize the by minimizing undershoots, overshoots, settling time. This paper proposed application novel Golden Eagle O...

Cyber attacks bring key challenges to the system reliability of load frequency control (LFC) systems. Attackers can compromise measured data critical variables LFC system, making received by defender unreliable and resulting in fluctuation or even collapse. In this paper, detect potential on data, we propose a novel attack detection scheme using dual-source (DSD) compromised variables. First, s...
