Abstract
In this work, we searched for the optimal node in East interconnected electrical grid Cameroon. By injecting electrical energy from photovoltaics. This makes it possible to meet the demand for electrical energy using renewable energies and to reach the maximum population. We first used the IEEE 33-node network to validate our algorithm, then we used a real electrical grid from EAST Cameroon. The main criterion is the minimization of active energy losses during injection. The algorithm used is the white-necked eagle algorithm was used. The method was implemented in MATLAB to find the optimal node in the radial network of 33 nodes. The results compared to the other methods show a reduced percentage of the total active losses in the network.
