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

Boundary Conditions for the Industrial Production of LFC Cells
2006 IEEE 4th World Conference on Photovoltaic Energy Conference, 2006 The `Laser-Fired Contact' (LFC) process scheme developed at Fraunhofer ISE is a fast, easy applicable and industrially feasible way of introducing the `Passivated Emitter and Rear Cell' (PERC) structure into solar cell production. Because the standard industrial production scheme needs to be adapted to the LFC process several further aspects have to be

Introducing dynamic demand response in the LFC model
2015 IEEE Power & Energy Society General Meeting, 2014 Demand response (DR) has proved to be an inevitable part of the future grid. Much research works have been reported in the literature on the benefits and implementation of DR. However, little works have been reported on the impacts of DR on dynamic performance of power systems, specifically on the load frequency control (LFC) problem.

A Robust Solution for PI-Based LFC Problem With Communication Delays [PDF]
IEEJ Transactions on Power and Energy, 2005 This paper addresses a new method to design a PI-based load-frequency control (LFC) with communication delays. First the LFC problem is reduced to a static output feedback control synthesis for a multiple delays system, and then the control parameters ...

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

Real Life Permissive LFC Model Description
2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2018This paper describes a permissive load frequency control (LFC) real life model for long-term time domain simulations. The model represents a supplementary control system to governor control systems based on area control error (ACE) calculation. Each forth second, ACE will be checked.

Design Philosophy of Long Range LFC Transports with Advanced Supercritical LFC Airfoils
1992With the interest in long range air transportation, the question arises concerning the design philosophy of long range LFC transports, which can reach any point on earth at high subsonic speeds with relatively large payloads without refuelling. Figure 1 shows as an example a 180,000 kg take-off gross weight LFC transport airplane with 50,000 kg payload

Effect of Casting Parameters on Porosity in LFC
Applied Mechanics and Materials, 2011Cast aluminium alloys often contain microstructural defects resulting from the casting process such as porosity. Developments of Lost foam casting (LFC) process is considered as one of the most rapid in casting technology owing to its unique advantages on energy savings and capabilities to produce castings with thin sections.

Decentralized ADRC for LFC in Deregulated Environments
International Journal of Engineering Practical Research, 2015Active disturbance rejection control (ADRC) method is investigated in this paper to design decentralized load frequency controllers (LFC) for deregulated multi‐area power systems. ADRC can treat the connections among control areas and the effects of possible contracts as new disturbance signals, and uses an extended state observer (ESO) to estimate and
