A PRACTICAL DECENTRALIZED LFC SYSTEM WITH GENERATION RATE LIMIT
IFAC Proceedings Volumes, 1989Abstract This paper presents a decentralized suboptimal LFC method based on output feedback control. In the proposed method, a centralized LFC system by optimal state regulator is first decomposed into a set of suboptimal LFC systems on the assumption that each subsystem can use the frequencies of adjacent areas.

Wave Interaction Theory and LFC
1992The complex high Reynolds number flows over modern swept wings can support at least three types of hydrodynamic instability; namely Gortler, Crossflow, and Tollmien-Schlichting instability mechanisms which can all cause transition to turbulence in many flows of practical importance.

Optimal Controller Design for LFC in Power System
2021In this paper, two-area interconnected power system is considered to study load frequency control problem. The state model of the two area is developed, and an optimal controller linear quadratic regulator (LQR) is designed to reduce the load frequency control (LFC) problem. A conventional PID controller is also used to study the dynamic performance of

Technical Challenge of Discrete Suction LFC Vehicles
OCEANS '79, 1979The drag and propulsive power of suction LFC undersea vehicles can be reduced by factors of 6 and 8, respectively, with accompanying reduction in self generated noise. This dramatic improvement in performance has not yet been demonstrated on an undersea vehicle, primarily because of two technical problems: (1) the prevention of ocean, particle capture ...

Comparison of three different metallization concepts for LFC cells
2010Laser fired contacts (LFC) are a well known technique to apply the rear side electrode on dielectrically passivated solar cells. Thereby, the aluminum on top of the passivation is locally heated by means of single laser pulses and subsequently alloyed into the silicon.

Casting Process Solutions Optimization of LFC Forklift Box
Applied Mechanics and Materials, 2014There are many advantages in producing forklift box through the LFC. However, we found shrinkage porosity defects in the interior of castings through simulating the original process by ProCAST casting simulation software. Therefore, we analyzed the defects and improved the technology program. firstly, increased riser in position of shrinkage, Secondly,

A novel adaptive LFC based on MPC method
IEEJ Transactions on Electrical and Electronic Engineering, 2019This article presents a novel load frequency control (LFC) method using an adaptive internal model of a power system, where model predictive control (MPC) technique is applied to the internal model, which is being updated on‐line. The proposed method will improve the LFC performance by reducing model identification error and by handling the disturbance
