Automatic generation control of an interconnected power system

Design of Load Frequency Controllers for Interconnected Power Systems with Superconducting Magnetic Energy Storage Units using Bat Algorithm

“…Where X, U and D are the state, control and disturbance vectors and A , B and  are respectively system state matrix, control input matrix and disturbance input matrix of appropriate dimension [9,10].…”

“…The objective is to obtain the optimum value of the controller parameters which minimize the performance index J [9,11]:…”

Artificial Intelligence in Performance Analysis of Load Frequency Control in Thermal-Wind-Hydro Power Systems

“…In addition, it is clearly shown that many control strategies have been developed for load frequency control/Automatic Generation control application through the past few years. Such control strategies are as: Parameter-plane technique [15], Lyapunov Technique [16], Continuous and Discrete mode Optimization [18], Optimal Control theory [19], Adaptive Controller [20], Variable Structure Control(VSC) [22], Decentralized controller [21], Conventional controller [23], Fuzzy Logic controller [5], Classical Controller [1], Integral Controller [1], Bat inspired algorithm (BID) [26], Beta Wavelet Neural Network (BWNN) [27], Teaching Learning Based Optimization (TLBO) [28], Firefly Algorithm [29], Cuckoo Search [30], on Multi Input The rest of the paper is organized as follows: Section II, describes the proposed system modeling. The proper controller and the design analysis are presented in section III.…”

GASA Tuned Optimal Fuzzy Regulator for AGC of an Interconnected Power System

“…In normal steady-state operation each control area of a power system should strive to meet its own load demand and in addition participate in regulating the frequency of the system. AGC is defined as the regulation of the power output of electric generators within a prescribed area in response to a change in system frequency and/ or tie-line loading, or the relation of these to each other, so as to maintain the scheduled system frequency and/or the established interchange with other areas within predetermined limits [1][2][3]. The conventional AGC regulators have been found inadequate to deal with complex integrated power system control problems because, they works on the trial and error principle [4].…”
