If Post-Normal Science Is The Solution, What Is The Problem?, Robert Hoppe, Anne Wesselink
If Post-Normal Science Is The Solution, What Is The Problem?, Robert Hoppe, Anne Wesselink
Robert Hoppe
Post-normal science (PNS) is presented by its proponents as a new way of doing science that deals with uncertainties, value diversity or antagonism, and high decision stakes and urgency, with the ultimate goal of remedying the pathologies of the global industrial system for which, according to Funtowicz and Ravetz (1993, 739) existing science forms the basis. We critically examine whether PNS can fulfil this claim in the light of empirical and theoretical work on politics and policymaking. We credit PNS as innovative frontrunner in raising important issues regarding the limited problem-solving capacity of ‘normal science’ and ‘professional consultancy’. Yet, we …
Robust And Intelligent Control Methods To Improve The Performance Of A Unified Power Flow Controller, C Benachaiba, Ahmed M. Haidar, M L. Doumbia
Robust And Intelligent Control Methods To Improve The Performance Of A Unified Power Flow Controller, C Benachaiba, Ahmed M. Haidar, M L. Doumbia
Faculty of Engineering and Information Sciences - Papers: Part A
The important factor disturbing the modern power systems today is load flow control. The Unified Power Flow Controller (UPFC) is an effective way for controlling the power flow and can provide damping capability during transient conditions. The UPFC is controlled conventionally using PI controller. This paper presents two robust controllers to improve the performance of the UPFC. The first is a RST controller based on the principle of pole placement and the second is an intelligent controller based on the principle of fuzzy logic optimized by Genetic Algorithm (GA).
