Development of optimization algorithms for a smart grid communityDevelopment of optimization algorithms for a smart grid community Μεταπτυχιακή Διατριβή Master Thesis 2014-12-152014enThe aim of this work is the development of an optimization model in order to minimize the cost of Leaf Community microgrid. This cost is a sum of energy cost and the maintenance cost of the Energy storage system. The developed objective function is constrained and the problem here is solved by using the method of genetic algorithms at Matlab. The genetic algorithm decides about the transportation of the energy from or to the ESS and it calculates an optimum cost. The optimization time horizon is 24 h ahead, thus the prediction of energy production and consumption was necessary. This was achieved by using neural networks. In order to verify the performance of the developed optimization model, some scenarios were tested evaluated. This study concludes that a management of a microgrid can achieve energy and money savings. http://creativecommons.org/licenses/by/4.0/Πολυτεχνείο Κρήτης::Σχολή Μηχανικών ΠεριβάλλοντοςProvata_Eleni_MSc_2014.pdfChania [Greece]Library of TUC2014-12-15application/pdf3.3 MBfree Provata Eleni Προβατα Ελενη Kolokotsa Dionysia Κολοκοτσα Διονυσια Kalaitzakis Konstantinos Καλαϊτζακης Κωνσταντινος Karatzas Giorgos Καρατζας Γιωργος Technical University of Crete Πολυτεχνείο Κρήτης Green energy investment Investment in clean energy clean energy investment green energy investment investment in clean energy Optimization, Constrained constrained optimization optimization constrained Industrial energy consumption industries energy consumption industrial energy consumption Artificial neural networks Nets, Neural (Computer science) Networks, Neural (Computer science) Neural nets (Computer science) neural networks computer science artificial neural networks nets neural computer science networks neural computer science neural nets computer science Alternate energy sources Alternative energy sources Energy sources, Renewable Renewable energy resources Sustainable energy sources renewable energy sources alternate energy sources alternative energy sources energy sources renewable renewable energy resources sustainable energy sources
