The Mini-Grid
Conventionally, the main source used to produce electricity in mini-grids is the diesel generator set (diesel genset). Diesel gensets operate by using diesel fuel which, like all fossil fuel types, is unsustainable and can harm the environment. Moreover, delivering diesel fuel to remote areas is difficult and may require one litre or gallon of diesel to deliver one litre or gallon of the fuel to certain rural areas. Therefore, the price of electricity can cost as much as 1.5 $ per kWh [3]. Figure 1-1 shows a simplified diagram
of a conventional mini-grid.
