An optimizer using the software component paradigm for the optimization of engineering systems

International Aegean Conference on Electrical Machines and Power Electronics and Electromotion, Joint Conference

2011

This paper is a methodological contribution in order to characterize two kinds of models that should be used in a complete optimization process of energy conversion systems like motors or actuators. We will indeed introduce the concept of "sizing model", and the concept of "optimization model". We will show also how to use them in a design process in order to produce optimal result that we concatenate in "an optimal design graph". All those methodological results will be illustrated on the optimal design of a Permanent Magnet Generator (PMG).

International audiencePurpose - The purpose of this paper is to make easily accessible models to test and compare the optimization algorithms we develop. Design/methodology/approach - For this, the paper proposes an optimization framework based on software component, web service, and plugin to exploit these models in different environments. Findings - The paper illustrates the discussion with optimizations in Matlab™ and R (www.r-project.org) of a transformer described and exploitable from the internet. Originality/value - The originality is to make easy implementation of simulation model and optimization algorithm coupling using software component, web service, and plugin

“…Two optimization environments have been used, which are: CPLEX (ILOG, 2007) and CADES (Delinchant et al, 2007). When solutions for energy management have been compared, two electrical sources strategies were found, each of it has different energy dispatching over time, but for the same value of the objective function.…”

et al. 2012

Purpose -The purpose of this paper is to introduce a problematic phenomenon that can occur when managing multi electrical sources systems by optimization. Design/methodology/approach -The energy management problem is formulated as a linear optimisation problem. Two approaches are developed and applied to detect the possible existence of equivalents solutions. The first is based on Dulmage-Mendelsohn (DM) decomposition. With this method the structure of the optimisation problem is analysed. The second approach is a numeric approach; the detection of equivalents solutions is made by the formulation of new optimisation problem and the objective function of this problem is to maximise the distance between two equivalents solutions. Findings -The numeric approach is more efficient than the structural approach. In some cases, applying DM decomposition may not be sufficient to detect the risk of W effect. This is because DM decomposition does not take the value of variable's coefficient into consideration, which is important to determine the degrees of freedom in the set of variables. Originality/value -Multi sources systems are widely used, especially in buildings where renewable energies have good potential application. The linear formulation of the management problem may induce an existence of equivalent command strategies. The detection approach presented in this paper shows that some solutions are better than others from an applicabability point of view. They will not exhaust rapidly the storage system. This approach can be implemented in virtual sources plant to avoid solutions with this so-called W effect.
