Evaluating national electric grid reliability by 2030 using the Barabási-Albert network model

Abstract

This study focuses on the development of a new probabilistic approach for reliability study it consists of studying the reliability of one of the North Africa electric grid, in order to propose an adequate production plan for 2030. A production plan where renewable energies take a large place in the production park, our objective is the planning and optimization of the energy system with a strong integration of renewable energy sources by guaranteeing the reliability of the electricity system in order to succeed in the energy transition. The reliability of a power system is a measure of its ability to supply the required electricity to its various points of use within acceptable standards. Indeed, the primary function of an electrical network is to provide reliable and economical power to its customers. However, the integration of renewables into the electricity grid leads to a change in the behavior of the electricity grid with respect to the satisfaction of electricity demand. Thus, in this article, we have evaluated the reliability of the electricity network in the presence of renewables energies based on probabilistic approaches more precisely the model of the Barabási-Albert network using Scale-free network. The model of Barabási Albert was applied for the first time on the electrical networks the case of the North American network and it gave good results if we compare it with the other usual methods that we decided to apply it on the Moroccan grid we compare the results.
