This paper deals with Automatic Generation Control (AGC) of a two area reheat thermal system with modified area control error (ACEM) considering operation of the system in the continuous-mode and that of the controller in the discrete mode. ACEM is the weighted sum of frequency deviation, tie-power deviation and inadvertent interchange energy. Studies show that the AGC-strategy based on ACEM pr...

In this paper, a multi-area Automatic Generation Control (AGC) scheme with Renewable Energy Sources (RES) suitable in a restructured interconnected power system has been proposed. Photo-voltaic and wind turbine generating system has been integrated with the grid. The developed scheme has been investigated for frequency control with and without RES units. A PID controller has been used to contro...

Abstract: A new intelligent Automatic Generation Control (AGC) scheme based on Evolutionary Algorithms (EAs) and Fuzzy Logic concept is developed for a multiarea power system. EAs i.e. Genetic Algorithm–Simulated Annealing (GA–SA) are used to optimize the gains of Fuzzy Logic Algorithm (FLA)-based AGC regulators for interconnected power systems. The multi-area power system model has three diffe...

Automatic generation control (AGC) of a multi area power system provides power demand signals for AGC power generators to control frequency and tie-line power flow due to the large load changes or other disturbances. Occurrence of large megawatt imbalance causes large frequency deviations from its nominal value which may be a threat to secure operation of power system. To avoid such situation, ...

AGC was implemented in first radios for the reason of fading propagation (defined as slow variations in the amplitude of the received signals) which 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, regardl...

A high performance automatic gain control (AGC) circuit of analog type is presented in this paper. The proposed AGC incorporates a modified sample and hold peak-detector. Circuit operations of this new peak-detector are demonstrated superior to the conventional one, by both keeping and tracking the peak of the input signal at the same time. Furthermore, the design complexity of the proposed AGC...
