Optimized self-sustained renewable DG integration in the Lebanese power grid

Abstract

With the increasing demand of power generation and the exhaustibility of the current energy sources, smart introduction of renewable sources on the distribution level is crucial. Lebanon has been facing a disastrous situation regarding the electricity sector. Forced cutoffs and failures are daily matters with no approaching solution. This paper is intended to give insights about the sustainable sources that should be distributed in a manner which not only reduces the total power losses and improves the voltage profile, but also decreases the current dependency on the central generation unit. An algorithm which assures this sustainability and self-reliance of the grid was performed and will be shown in details. Results obtained clearly prove that in addition to its reliability and compatibility, the grid will be able of minimizing the power losses of the system and will function in absolute autonomy. Once the distributed generations of optimum size are installed at the optimum location and the algorithm ran, losses will be reduced to around 70% of their initial value, the voltage profile will be enhanced, and the main grid will not anymore supply power but instead will become a feeder to the neighboring branches of the system.
