Power Flow Management of Grid Connected Micro-grid

Abstract

In this paper, a novel control method for the power flow management of grid connected with transformer-battery based system including bidirectional (BL) DC-DC converter is presented. The objective of this proposed system is to satisfy the load demand and control the power flow management from the different sources. A BL boost converter is used to boost the power from the wind and connected with battery charging or discharging. Rectifier is used here to convert AC to DC and that the received DC supply gets boost up by DC-DC boost converter. A BL converter is used for supplying loads. The advantage of the proposed work is simple in operation, minimizes the losses and feeds the extra amount of power into the grid. The battery can be charged from the grid also whenever it is required.
