Abstract

With the advances in the manufacturing of photo voltaic cells, DC-DC micro grids are gaining a lot of attention. With the concept of parallel operation of different Dc energy sources like photo voltaic cells, fuel cells, storage banks like super capacitors and different type of batteries has evolved the structure of Dc micro grids. To get benefit from the concept of dc micro grids, the problem of circulating currents among parallel energy sources must be solved. Due to very low resistance of dc micro grids, a voltage difference of few millivolts between two energy sources may cause one source to operate at full load while the other being idle. This research paper proposes a sliding mode control to solve the problem of circulating currents and unbalanced load sharing. A comparison of SM control with PID control is also presented.
