Abstract: This paper shows a new method for optimization of the general investment cost in a distribution network supplied by solar photovoltaic (PV) source. This method consists of first, determining, the optimal cross sections for electrical cables used between solar generator and loads and second, find the optimal placement of loads distribution center such that the cost sum of installation and exploitation, of the investment, are considerably reduced to its optimal value. Particular method has been presented in previous study, where the optimization of the solar generator placement, is based on network having identical cables cross sections. However, our work was performed on the general case in view of the influence of technical and economical cable cross sections, operating hours or time periods of loads and the possibility to use more than one solar generator with several separated networks. The supply point that corresponds to the lowest general investment cost is referred as the Optimal Loads Distribution Centre “OLDC” which can also be referred to the Optimal Volume Center “OVC” if the exploitation details are not known. The OLDC method was applied on several examples, one of the most general and difficult case is presented in this article. The results of the analysis are found satisfactory since the adoption of the optimal number of loads distribution centers in their optimal places, taking into account the operating hours of loads with time periods, helped reducing drastically the general cost of the investment.
