A novel method to determine the best size of CHP for an energy hub system
, Article 2011 2nd International Conference on Electric Power and Energy Conversion Systems, EPECS 2011 ; 2011 ; 9781457708060 (ISBN) ; Ranjbar, A. M ; Safe, F ; IEEE; Power and Energy Society (IEEE PES); Abu Dhabi Water and Electricity Authority ; Sharif University of Technology
Abstract
Today, the interest on distributed generation has been increasing, especially due to technical development on generation systems that meet environmental and energy policy concerns. One of the most important distributed energy technologies is Combined Heat and Power (CHP). CHP is small and self-contained electric generation plan that can provide power for household applications, commercial or industrial facilities and hence its applications are overtly increasing. It can reduce power loss and enhance service reliability in distribution systems. One of the influential factors for the users is the purchasing cost of CHP which is largely dependent on its type, capacity and efficiency. Therefore...

Global hybrid modeling and control of a buck converter: a novel concept

Abstract
Several attempts have been made to design suitable controllers for DC-DC converters. However, these designs suffer from model inaccuracy or their inability to desirably function in both continuous and discontinuous current modes. This paper presents a novel switching scheme based on hybrid modeling to control a buck converter using mixed logical dynamical (MLD) methodologies. The proposed method is capable of globally controlling the converter in both continuous and discontinuous current modes of operation by considering all constraints in the physical plant such as maximum inductor current and capacitor voltage limits. Different loads and input voltage disturbances are simulated in MATLAB...
