The analyze of solutions for supplying the electrical energy to rural isolated areas consumers

In Romania there are still almost 2500 relatively isolated small rural communities with no, or only partial, electrification. The first part of the paper is a presentation of the isolated settlements in Romania that need electrification: number of inhabitants, distances, electricity demand and load forecast. The Romanian regulatory framework on this matter is also presented. The latter part of the paper shows some feasible technical solutions and the criteria and indicators for a comparative analysis of such solutions in terms of the investment costs, operation and maintenance costs and specific consumption. The third part of the paper shows the assessment results, based on indicators, of the technical solutions for the electricity supply of the isolated settlements in the district of Bihor (MV network, LV network, distributed generation) while establishing the optimum variant for each case. This study conclusions are presented in the last part of the paper.
