Strategic framework of an energy management of a microgrid with a photovoltaic-based active generator

Abstract

By taking into account the fluctuations of renewable energy based power production (photovoltaic panels) and the ancillary services supply to a microgrid (improvement of the availability and capacity of the power from Renewable Energy Source, uninterruptible supply of critical loads, micro grid power quality improvement, peak shaving, load shifting, reactive power supply/compensation etc.), this paper describes an energy management of a micro grid with a PV-based active generator. This energy supervision is implemented into two parts: a central energy management of the microgrid and a local power management in the active generator. Between them information and orders are exchanged. Our energy supervision is organized in different functions. In this paper we present the following functions: the prediction of the power production and the load forecasting; power planning and the real time power regulation.
