Abstract
The research is focused on the control of heterogeneous battery storage systems by taking into account the chemical processes inside a battery which are reflected in variable battery efficiency and consequently, battery longevity. This is motivated by economic benefits that stem from more efficient control of microgrid components in microgrid optimal power flow problems. The control objective is formulated as a model predictive control problem and decomposed into two levels. The higher level is in charge of microgrid optimal power flows and is based on a high level of abstraction model of storage system. The lower level is based on a detailed storage system model and is in charge of delivering the demanded power profiles in the most efficient way. The battery converter model includes power-dependent efficiency in the form of look-up-tables and the internal resistor of the battery model is a function of battery states. The parameters are obtained by model-based identification techniques.
Abstract (croatian)
Istraživanje se fokusira na upravljanje heterogenim baterijskim sustavima za pohranu uzimajući u obzir kemijske procese unutar baterija koji se odražavaju u obliku promjenjive učinkovitosti, a posljedično i dugotrajnosti sustava. Istraživanje je motivirano ekonomskom korišćuu koja proizlazi iz efikasnijeg upravljanja mikromrežnim komponentama prilikom rješavanja problema optimalnih tokova snaga u mikromreži. Modelski prediktivni upravljački problem rastavljen je na dvije razine. Viša razina upravlja tokovima snaga u mikromreži, a temelji se na pojednostavljenom modelu baterijskog sustava. Niža razina temelji se na detaljnom modelu, a zadužena je za ostvarivanje traženih profila snaga na najefikasniji način. Model pretvarača baterije uključuje promjenjivu efikasnost ovisnu o snazi, a unutarnji otpor baterije funkcija je trenutnog stanja baterije. Vrijednosti parametara dobivaju se metodama identifikacije temeljenim na modelu.
