The fast-increasing introduction of renewable energy sources (RESes) leads to some problems in electrical power network due to fluctuating generated power. A power system must be operated with provision of various reserve powers like governor free capacity, load frequency control and spinning reserve. Therefore, the generator’s schedule (unit commitment schedule) should include the consideratio...

Multi-area load frequency control (LFC) selects and controls a few generators in each area of the power system an effort to dampen inter-area oscillations. To effectively such oscillations, it is required enhance lower activity dynamically during operation, so as adapt changing circumstances. Changing circumstances should cover not only parametric uncertainties unmodelled dynamics (e.g. aggrega...

This paper proposes a new control strategy to consider the doubly fed induction generator (DFIG) wind generation contribution in frequency control and regulation of multi-area interconnected power system when the wind power is the main generation of one area. Based on frequency requirements and system conditions, the proposed control approach determines whether to switch the wind generation int...

This study develops and implements a design of the Fuzzy Proportional Integral Derivative with filtered derivative mode (Fuzzy PIDF) for Load Frequency Control (LFC) two-area interconnected power system. To attain optimal values proposed structure’s parameters which guarantee best possible performance, Bees Algorithm (BA) other optimisation tools are used to accomplish this task. A Step Perturb...

This paper incorporates the techniques of design of an optimal neural network controller for load frequency control(LFC) to regulate the power output as well as the system frequency of a two-area power system by controlling the speed of the generator by means of controlling the steam flow. The controller is obtained using a combination of genetic algorithm, and neural network. The aim of the co...

Load frequency control (LFC) is necessary to guarantee the safe operation of power systems. Aiming at and stability problems caused by load disturbances in interconnected systems, active disturbance rejection (ADRC) was designed. There are eight parameters that need be adjusted for an ADRC, which challenging adjust manually, thus limiting development this approach industrial applications. Regar...

Due to the increasingly marketized demands of power systems, dedicated communication channel used by traditional load frequency control (LFC) scheme is ineluctably replaced highly open networks, which may introduce constant, and time-varying delays. Hereupon, for those two kinds methods, this article explores LFC problem systems in consideration By utilizing Lyapunov stability theory, an improv...

The load frequency control (LFC) problem in interconnected multiarea power systems is facing more challenges due to increasing uncertainties caused by the penetration of intermittent renewable energy resources, random changes patterns, system parameters and unmodeled dynamics, leading a compromised reliability risk outages. In responding this problem, paper proposes decentralized disturbance ob...

Abstract In this work, chaos game optimization (CGO), a robust approach, is employed for efficient design of novel cascade controller four test systems with interconnected power (IPSs) to tackle load–frequency control (LFC) difficulties. The CGO method based on theory principles, in which the structure fractals seen via chaotic principle and fractals’ self-similarity characteristics are conside...
