New network design for simultaneous use of electric vehicles, photovoltaic generators, wind farms and energy storage

Abstract

Renewable energy deployment in a real-time power distribution system is complicated by the unreliability of continuous output. The use of an appropriate mix of the two renewable energy source technologies, PV¹¹photovoltaic and WT²²wind turbines in conjunction with the usage of an energy storage device, as an example a battery system, as a form of power balancing medium, might address output intermittency and dependability concerns. Different storage methods might help with the unreliability problem, but they consume a lot of electricity and produce a lot of expenses and carbon emissions. As a temporary distributed energy storage device, two-way power transfer capability in plug-in electric cars (V2G³³Vehicle-to-Grid, G2V⁴⁴Grid-to- Vehicle) and electric vehicles are an option. In this study, the benefits of two wind and solar resources are compared in a weak low-voltage distribution system, and it is demonstrated that using these two resources together may overcome the problems of generating renewable resources with a stochastic nature. An uneven power distribution, the behavior of the grid at the PCC⁵⁵point of common coupling in the presence of a wind turbine, solar generator, and electric vehicle was also studied. Finally, the stability of transients has been investigated under various fault situations. The DIgSILENT PowerFactory program is used to run simulations.
