Abstract

Micro grid provides the integration of the various micro energy resources, load, energy storage devices and power electronic converters forming a system. Micro grid usually operates when it is being connected to the grid but during emergency time it is capable of working in a standalone mode. Operational control during both modes is of utmost concern. In this paper the standalone MG system which has been considered has a reduced battery capacity as the battery is being connected to DC link with the help of bidirectional converter which acts as a buck converter while charging the battery and act as a boost converter while discharging the battery. The bidirectional converter is capable of reducing the size of battery in comparison to a system where battery is directly connected to the DC link. Various control strategies need to be formulated for controlling the power electronic converters. The basic strategy which has been introduced is master slave, peer to peer and hierarchical control. Master and hierarchical based on centralized control and operate on the basis of communication system. Peer to peer is used for local information that is being used to make decisions. The model is designed in the real time digital environment and the priority schedules are maintained accordingly.
