Abstract: The Load Frequency Control problem has been a major subject in electrical power system design/operation and is becoming more significant recently with increasing size, changing structure and complexity in interconnected power systems. In practice LFC systems use simple proportionalintegral controllers. However, since the PI control parameters are usually tuned based on classical or tr...

Since renewable energy sources (RESs) have an intermittent nature, conventional secondary frequency control, i.e., load control (LFC), cannot mitigate the effects of variations in system frequency. Thus, this paper proposes incorporating ultralocal model (ULM) into LFC to enhance microgrid (µG) stability. ULM controllers are regarded as model-free that yield high rejection rates for disturbance...

A large penetration of photovoltaic and wind power generation causes the imbalance between supply and demand in power systems because their output is intermittent. To alleviate the mentioned problem, many researches on Load Frequency Control (LFC) using Electric Vehicles (EVs) as controllable loads have been studied. In this paper, we propose a new LFC method using EVs, which is named the State...

Load frequency control in power systems introduces as one of the most important items in order to supply reliable electric power with good quality. The goals of the Load Frequency Control (LFC) are to maintain zero steady state errors in a two area interconnected power system. To achieve this goal a fast controller with having no steady-state error will be necessary to be included in power syst...

In this paper, a robust Takagi-Sugeno Fuzzy Parallel Distribution Compensation (TSFPDC) technique is proposed for the solution of Load Frequency Control (LFC) problem in the interconnected power system. In this strategy, control signal is tuned online from the knowledge base and the fuzzy inference which request fewer sources. In order to minimize the efforts of load disturbances and achieve th...

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...

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...
