Public ISBD Titre : A local energy management and coordinated control of an active PV generator connected to an electric smart microgrid Type de document : texte imprimé Auteurs : Adel Choudar, Auteur ; Boukhetala, Djamel, Directeur de thèse Editeur : [S.l.] : [s.n.] Année de publication : 2017 Importance : 127 f. Présentation : ill. Format : 30 cm Accompagnement : 1 CD-ROM. Note générale : Thèse de Doctorat : Automatique : Alger, Ecole Nationale Polytechnique : 2017 Bibliogr. f. 123 - 127. Annexes f. 116 - 121 Langues : Anglais (eng) Mots-clés : Microgrid Distributed  energy  resources Distributed  storage Active  PV  system Energy  management PV  limitation  mode Batteries Ultra-capacitor Index. décimale : D003317 Résumé : The presented work focuses on energy management strategy, to optimize the operation of a grid connected active PV system (APS) in a microgrid. A microgrid is a smart grid in a small scale which can be stand-alone or grid-tied. The proposed system is based on a photovoltaic generator, batteries and ultracapacitors. Three converters are used to interface the elements of the APS to a common DC-link capacitor. The presented control strategy manages the power flow between the converters and the grid through the DClink in order to maintain the grid power demand coming from the grid operator. Batteries are used as an energy source, to stabilize and permit the APS units to run at a constant and stable output power, damping peak surges in electricity demand and to store the excess of energy from the PV array. Ultra-capacitors are used as a fast power regulator to: limit the battery’s current, regulate the DC-link voltage when the disconnection mode occurs and to deliver a smooth power to the grid, despite primary source and load fluctuations. Several operating modes are presented to manage locally the power flows between the various sources, taking into account the state of charge of batteries (SOC), the energy level of ultra-capacitors (Lev), the available PV power and the power demand from the grid operator.
