Over the years, several achievements have been made in power generation and optimising hybrid renewable energy systems (HRES) to achieve nature conservation, security, reduce carbon emissions. However, there are many complexities Renewable (RE) conversion, sizing, design, implementation, that require optimisation techniques optimal results terms of reliability, cost, environmental protection ov...

Distribution networks were conceived to distribute the energy received from transmission and subtransmission supply passive loads. This approach, however, is not valid anymore due presence of distributed generation, which mainly based on renewable energies, increased number plug-in electric vehicles that are connected at this voltage level for domestic use. In paper ongoing transition distribut...
