Power Management of Micro Grid under is Landed and Grid Connected Mode of Operation

Abstract

Power management is a feature that permits users to manage the quantity of electric power consumed by the underlying devices, with smallest impact on performance of the system irrespective of its mode of operation. It permits the switch of devices in varied power modes with totally different power usage characteristics associated with device performance. Particularly in island or off grid mode, a microgrid plays vital role by integrating different sources of distributed generation (DG) and Renewable Energy Sources (RES). Typically plants run in synchronization with grid. Anyway normally plants have their islanding mode empowered, which can mechanically island or segregate the plant if there's some outside unsettling influence inside the grid. This paper is concerned with the dynamic and reactive power sharing of DGs with change in load. Here the power profile of three distributed energy resources are obtained with the impact of variable load and all the results are obtained by using MATLAB simulink.
