Optimal selection of LQR parameter using AIS for LFC in a multi-area power system

Journal of Mechatronics, Electrical Power, and Vehicular Technology, 2016
This paper proposes a method to optimize the parameter of the linear quadratic regulator (LQR) using artificial immune system (AIS) via clonal selection. The parameters of LQR utilized in this paper are the weighting matrices Q and R.

Optimasi LFC (Load Frequency Control) Pada Mikrohidro Menggunakan Metode ACO-ANFIS dan BA-ANFIS

Nucleus Journal
Micro-hydro Power Plant is a small-scale power plant. Micro-hydro plants are built with enough water potential to generate electrical energy. A common problem with micro-hydro generating systems is that the output of the generator is not constant. This is caused by changes in connected loads.

Arabidopsis EMB2788/Npa1L1 is critical for pre‐rRNA processing, ribosome biogenesis, and embryo development

The Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY Ribosome assembly, a fundamental process for cellular functions, requires the precise processing of precursor rRNA (pre‐rRNA) into mature rRNAs, a transformation guided by ribosome biogenesis factors (RBFs). While this process is well characterized in yeast and mammals, the roles of RBFs in pre‐rRNA processing in plants remain poorly understood.

Design Of Optimal Linear Quadratic Gaussian (Lqg) Controller For Load Frequency Control (Lfc) Using Genetic Algorithm (G.A) In Power System

, 2018
Nowadays power demand is increasing continuously and the biggest challenge for the power system is to provide good quality of power to the consumer under changing load conditions. When real power changes, system frequency gets affected while reactive power is dependent on variation in voltage value.

HYBRID GREY WOLF OPTIMIZATION-PATTERN SEARCH (hGWO-PS) OPTIMIZED 2DOF-PID CONTROLLERS FOR LOAD FREQUENCY CONTROL (LFC) IN INTERCONNECTED THERMAL POWER PLANTS

ICTACT Journal on Soft Computing, 2016
The combination of Grey Wolf Optimization and Pattern Search Technique (hGWO-PS) has been introduced to optimize the parameters of two Degree of Freedom Proportional-Integral-Derivative Controller (2DOF-PID) for controlling the load frequency in Automatic Generation Control (AGC) for interconnected power system. The interconnected two area power system

Load Frequency Control in Two Area Power System using ANFIS [PDF]

, 2014
The load-frequency control (LFC) is used to restore the balance between load and generation in each control area by means of speed control. The main goal of LFC is to minimize the transient deviations and steady state error to zero in advance. This paper

Load Frequency Control (LFC) Menggunakan Metode Noise-Tolerable PID Feedback pada Power Generation Plant Simulator PLTU PT. Pembangkitan Jawa dan Bali (PJB) Unit Pembangkitan (UP) Paiton

Jurnal Teknik ITS, 2017
Frekuensi sebesar 50 Hz harus dijaga agar memberikan kualitas energi listrik yang baik. Pengaruh dari switching pada sisi beban akan membuat frekuensi energi listrik menjadi fluktuatif. Nilai frekuensi yang fluktuatif akan membuat fungsi derivatif pada kontroler Proportional Integral Derivative (PID) menjadi sangat besar, sehingga akan mempengaruhi ...
