<Para ID="Par1">We consider parameter optimization problems which are subject to constraints given by parametrized partial differential equations. Discretizing this problem may lead to a large-scale optimization problem which can hardly be solved rapidly. In order to accelerate the process of parameter...</para>

This paper presents development of an optimal control strategy for a hybrid photovoltaic/battery energy storage (PV/BES) system. The fluctuations at the DC bus voltage due to voltage sag were mitigated by using charge/discharge capability of the BES through the DC/DC buck/boost converter....
