The main objective of Load Frequency Control (LFC) is to regulate the power output of the electric generator within an area in response to changes in system frequency and tie-line loading .Thus the LFC helps in maintaining the scheduled system frequency and tie-line power interchange with the other areas within the prescribed limits. Most LFCs are primarily composed of an integral controller. T...

In this paper, a new artificial intelligence technique, Harmony Search (HS), will be used for the optimization of a classical order PID for a two-area load frequency control (LFC) model using the participation factor concept. The HS has four main variants, these variants had been used for the optimization of classical order PID controllers in case of centralized control scheme, the results had ...

This based on two metrics: LFC power. consists thermal plant generation hydro evaluated by designing proportional plus integral (PI) controller. hybrid gravitational search with firefly algorithm (hGFA) has been dev...

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...

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...
