Micro hydro is treated as a major renewable energy resource. Such a kind of plants blooms because they can evade some dilemmas like population displacement and environmental problems. But their performance on the frequency index of power systems may be deteriorated in the presence of sudden small load perturbations and parameter uncertainties. To improve the performance, the problem of load fre...

Recently several robust control designs have been proposed to the load-frequency control (LFC) problem. However, the importance and difficulties in the selection of weighting functions of these approaches and the pole-zero cancellation phenomenon associated with it produces closed loop poles. Also the order of robust controllers is as high as the plant. This gives rise to complex structure of s...

Frequency stability of the power system is impacted by increasing penetration wind because intermittent. Meanwhile, sometimes demand side loads increase quickly to require more than total produced. So balancing active in maintain frequency main challenge high smart grid. This paper proposes coordination rotor speed control (RSC), pitch angle (PAC) and inertial (IC) turbines, together with respo...

In this article, Load Frequency Control (LFC) of three area unequal interconnected thermal, wind and Hydro power generating units has been developed with ProportionalIntegral (PI) controller under MATLAB/SIMULINK environment. Further, the PI controller gains values that optimized using trial and error method with two different objective functions, namely the Integral Time Square Error (ITSE) an...

With the high penetration of wind turbines, many issues need to be addressed in relation load frequency control (LFC) ensure stable operation power grids. The particle swarm optimization-based model predictive (PSO-MPC) approach is presented address this issue context LFC with participation turbines. classical MPC was modified incorporate optimization algorithm for generation regulate system fr...

Load frequency control plays a vital role in power system operation and control. LFC regulates the frequency of larger interconnected power systems and keeps the net interchange of power between the pool members at predetermined values for the corresponding changes in load demand. In this paper, the two-area, hydrothermal deregulated power system is considered with Redox Flow Batteries (RFB) in...

A Firefly Algorithm (FA) based on Fuzzy PID controller is proposed in this paper to solve the Load Frequency Control (LFC) problem in a deregulated environment. In multi area electric power systems, if a large load is suddenly connected (or disconnected) to the system, or if a generating unit is suddenly disconnected by the protection equipment, there will be a long-term distortion in the power...

In this paper work we analyze and design Automatic load frequency control of two areas power system using Genetic Algorithm and also for four area power system using artificial neural network (ANN), generation control is becoming increasingly important in view of increased load demand & reducing generating resources. The increasing load demands are posing serious threats to reliable operation o...

Bayesian Networks (BN) provides a robust probabilistic method of reasoning under uncertainty. They have been successfully applied in a variety of real-world tasks but they have received little attention in the area of load-frequency control (LFC). In practice, LFC systems use proportional-integral controllers. However since these controllers are designed using a linear model, the nonlinearities...

The congest in an open communication system may cause the failure of load frequency control (LFC) scheme power system. Furthermore, increase wind penetration degrades stability LFC scheme. To address these two issues, this paper analysis schemes with both Bernoulli model and Gilbert-Elliott packet losses based on Markov jump effect also discussed as inertia reduction. Moreover, combined action ...
