To preserve the natural balance, stability, and reliability of an electric power system, its frequency is one most relevant variables to control; therefore, control schemes by stages are used. In particular, secondary regulation, also known as automatic generation (AGC), performed remotely from a system operator’s center in cases using efficient energy management systems (EMS). They use SCADA-A...

This paper formulates the automatic generation control (AGC) problem as a stochastic multistage decision problem. A strategy for solving this new AGC problem formulation is presented by using a reinforcement learning (RL) approach. This method of obtaining an AGC controller does not depend on any knowledge of the system model and more importantly it admits considerable flexibility in defining t...

We study a class of matrices with rank-1 interconnection structure, and derive simple necessary sufficient condition for diagonal stability. The underlying Lyapunov function is used to provide conditions stability approximately interconnections. main result then leveraged as key step in larger analysis problem arising power systems control. Specifically, we the first theoretical automatic gener...

This paper presents a new simplified AGC model for deregulated power systems. New AGC model facilitates us to design the controller without considering bilateral contracts. And also concentrates only the load disturbances not on the contracted loads. New AGC in deregulated power system is modeled by modifying conventional model with inclusion of bilateral contracts. Bilateral contracts will all...

This paper addresses an integral sliding mode control approach for automatic generation control (AGC) of a single area power system. Genetic algorithm (GA) is employed to search the parameters of the sliding surface. The proposed design is investigated for AGC of a single area power system, made up of reheated thermal and gas power generations. Compared with the GA-based proportion-integral (PI...

This paper investigates the effects of knowledge-based acceleration feedback control integrated with Automatic Generation Control (AGC) to enhance the quality of frequency control of governing system. The Intelligent Acceleration Feedback Controller (IAFC) is proposed to counter the over and under frequency occurrences due to major load change in power system network. Therefore, generator tripp...

A Decision Table looking up algorithm for Fuzzy Logic Controller (FLC) with Genetic Algorithm (GA) optimization for Automatic Generation Control (AGC) system is developed. The single-input single-output (SISO) cascade loop structure of the AGC system is analyzed first. Then the interaction between the fast Area Control Error (ACE) loop and slow inner Boiler-Turbine-Generator (BTG) loop is decou...

Automatic generation control (AGC) is added in power system to ensure constancy in frequency and tie-line power of an interconnected multi-area power system. In this article, proportional integral (PI) controlled based AGC of two-area hydrothermal system is solved by cuckoo optimization algorithm (COA). It is one of the most powerful stochastic real parameter optimization in current use. The de...

This paper presents the particle swarm optimization (PSO) technique to optimize the integral controller gains for the automatic generation control (AGC) of the interconnected power system before and after deregulation. Each control area includes the dynamics of thermal systems. The AGC in conventional power system is studied by giving step load perturbation (SLP) in either area. The AGC in dere...

This paper addresses a new decentralized robust strategy to adapt the well tested classical automatic generation control (AGC) system to the changing environment of power system operation under deregulation based on the bilateral AGC scheme. In each control area, the effect of bilateral contracts is taken into account in a modified traditional dynamical model as a set of new input signals. The ...
