Design and Simulation of Solar DC Nano Grid System from Bangladesh Perspective

There has been seen continuous search for alternative sources to generate adequate electrical power in Bangladesh, yet some areas of the country still don’t have access to it. Solar DC Nano grid can be a possible approach towards achieving electrification to certain areas where grid connectivity is still unavailable. It can generate and distribute power to a cluster of households at close proximity reliably. This research paper proposes a model of DC Nano grid integrated with solar PV module which can supply electricity to up to 20 households at a distance of about 1 km. This paper provides simulation results of buck converters assigned to supply power at three different voltage levels to feed various domestic loads. Along with this, cost estimation is presented of the proposed model which motivates the implementation of the Nano grid.
