Automatic Generation Control (AGC) is one of the ancillary services that have become important in the deregulated power system environment. Together with the fact that the load varies rapidly throughout the day, it is imperative to have a system that will maintain a continuous and reliable flow of power within the system. Long ago, system operators recognized this fact by requiring power pools ...

An electric supply with reliable and good quality is very important in power system operation and control. To achieve reilability and quality in interconnected power system Automatic Generation Control (AGC) is used. The components of AGC are change in frequency deviation (∆F) and tie-line power flow (∆Ptie). For any load change, there is an existence of (∆F) and (∆Ptie) which are used as a fee...

Abstract: A decentralized state estimation method for automatic generation control (AGC) of interconnected power systems is proposed in this paper. Based on the Inclusion Principle for linear stochastic systems, the state space model of the system is decomposed as a group of pair-wise subsystem models. The overlapping decentralized estimators and fully decentralized estimators are designed for ...

It has been proposed recently that the control policy for Automatic Generation Control (AGC) of an interconnected power system can be learnt through a Reinforcement Leraning (RL) approach [7]. In this method, which is the first application of RL techniques for power system control problems, it was assumed that the input variables to an AGC take only discrete values. However, in a power system, ...

Due to the continuous change in load, the frequency and tie-line power of control areas get disturbed from their scheduled value which is undesirable. Automatic Generation Control (AGC) is an essential mechanism in electric power systems which balance generated power and demand in each control area in order to maintain the system frequency at nominal value and tie-line power at its scheduled va...

In the early years of radio circuits, fading (defined as slow variations in the amplitude of the received signals) required continuing adjustments in the receiver's gain in order to maintain a relative constant output signal. Such situation led to the design of circuits, which primary ideal function was to maintain a constant signal level at the output, regardless of the signal's variations at ...

This paper presents the analysis of automatic generation control of a two-area interconnected thyristor controlled phase shifter based hydrothermal system in the continuous mode using fuzzy logic controller under open market scenario. Open transmission access and the evolving of more socialized companies for generation, transmission and distribution affects the formulation of AGC problem. So th...

Automatic generation control or AGC system is substantial control process that operates perpetually to balance the generation and load in power system at minimum cost. If any kind of mismatch occurs between generation and demand causes the variation in the system frequency from its nominal value. This high frequency deviation may cause system breakdown. In order to maintain the stability, a ver...

As the installation of electronically interconnected renewable energy resources grows rapidly in power systems, system frequency maintenance and control become challenging problems to maintain reliability bulk systems. two most important actions centers independent operators (ISOs) utilities, interaction between Economic Dispatch (ED) Automatic Generation Control (AGC) attracts more attention. ...
