Abstract

The rapid increment of DC compatible appliances in the buildings, emerge the photovoltaic energy as the fastest growing source of renewable energy and expected to see continued strong growth in the immediate future. The photovoltaic power is, therefore, required to be provided with a certain reliability of supply and a certain level of stability. Motivated by the above issues, many grid operators have to develop DC micro-grids, which treat photovoltaic power generation in a special manner. The interconnection of different voltage rating distributed generation, storage and the load to the DC micro-grid requires large number of converters, which will increase the conversion power losses and the installation cost. Different types of Low Voltage Direct Current (LVDC) grid and their topologies are helpful in understanding the interconnection of distributed generation with consumers end. The connections of LVDC distribution system is discussed in this chapter. Optimization of LVDC grid voltage may reduce the conversion stage and the power loss in DC feeders. A multi-objective technique is discussed, in this chapter, to design a minimum power loss and low cost DC micro-grid.
