This paper presents a new robust decentralized controller based on mixed H2/H∞ control technique for the solution of Load Frequency Control (LFC) in a deregulated electricity environment. To achieve decentralization in each control area, the connections between this area and the rest of the system and the effects of possible contracts are treated as a set of new disturbance signals. It is shown...

The introduction of electrolytic aluminum load in a large-scale power system with complex station structure is essential for frequency control (LFC).

A simple and computationally efficient decentralised control design method is introduced for load-frequency control (LFC) in interconnected power systems. The method is based on the use of a reduced-order observer and a proportional-plus-integral controller in each area of the power system, and ensures zero static change in area-frequency and tie-line power. Some of the features of the decentra...

The application of battery energy storage (BES) in microgrid systems has attracted much attention recent years. It is because the BES able to store excess power and discharge its when needed. In islanded systems, starting be considered as a unit that can regulate system frequency. control used display frequency regulation performance called load-frequency (LFC). However, this participation resu...

A new robust load-frequency control (LFC) methodology is proposed for controlling uncertain nonlinear power systems. Critical nonlinearity in the power system—the valve position limit on the governor, and the parametric uncertainty are concerned. The Takagi–Sugeno fuzzy model of the power system under consideration is first constructed to design the robust fuzzy-model-based LFC. Sufficient cond...

Received Apr 5, 2017 Revised May 20, 2017 Accepted Jun 15, 2017 In this study, an optimal meta-heuristic optimization algorithm for load frequency control (LFC) is utilized in two-area power systems. This metaheuristic algorithm is called harmony search (HS), it is used to tune PI controller parameters (Kp, Ki) automatically. The developed controller (HSPI) with LFC loop is very important to mi...
