Influence of standard sections and time periods on optimization of a distribution network supplied by solar source

Abstract

This paper shows the influence of cables standard sections and time periods on the location of solar energy generator, in order to optimize its distribution network. These parameters can influence considerably the whole cost of installation during the running of a project. An approach of resolution consists of determining the emplacement of the solar generator. For the electrical cables sections with a constant voltage drop, it is then placed in the electrical center of gravity 'E.G.C’ of various loads that surrounds it. However, for cross sections which cover all installation conditions (standard sections), the generator is not in the gravity center (E.G.C), this optimal position (O.G.P) is known as having minimum of copper volume, that mean the least cost of cable for the complete installation. The determined standard sections for each cable, in this positions, are the smallest technically acceptable. An optimal section has been calculated in order to achieve the lowest annual cost of the investment. The obtained results prove that the adoption of this section has an effective economical profit in terms of energy gain.
