Exergy analysis of the LFC process
Energy Conversion and Management, 2016Liquid from coal (LFC) is a pyrolysis technology for upgrading lignite. LFC is close to viability as a large-scale commercial technology and is strongly promoted by the Chinese government. This paper presents an exergy analysis of the LFC process producing semicoke and tar, simulated in Aspen Plus.

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.

Boundary Conditions for the Industrial Production of LFC Cells
2006 IEEE 4th World Conference on Photovoltaic Energy Conference, 2006The `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, 2014Demand 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 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

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
