A framework for incorporating load profiles for sizing and designing of microgrid

Abstract

Reliance to electrical energy in all sectors of life have raised concerns about supply demand mismatch leading to frequent grid outages for centralized systems. Microgrids are localized power generation units which can be a combination of mostly renewable sources, loads and storage devices. Variable nature of renewable sources, demand for long term and short term storage, depending on the user scenario. This paper presents a novel approach for microgrid component design using automated software program. The work aims at presenting a Graphical User Interface based on Visual Basic .Net and XML database, which helps to identify optimum selection of variable sources and storage devices for a microgrid, based on daily demand. Parameters are designed to maximize the efficiency and effectiveness, both in terms of energy, cost and life cycle, focused on sustainability. Lead Acid storage is used commonly as medium term storage option in microgrids but other electrochemical storages are also examined.
