The improvements and implementation of new generation equipment to the conventional grids are increasing along with the increase of the number of renewable energy power plants and smart grid components. The existing grid infrastructure is required to be modified and upgraded as a result of the increasing integration of the renewables and new generation consumers where the availability of the existing networks has to be analyzed for integration as well. In order to keep the grid stable and integrate the renewables to the grid optimally, necessary analyses have to be realized including the investigation of the optimal integration criteria. During the integration phase of the new generation consumers and producers, two ways power flows and variable power production of renewables have to be considered for system design. In this study, analysis for optimal sizing and integration studies are performed for electric vehicle parking lot and solar power plants located on the campus distribution network considering optimal sizing criteria and the aim of stabilization of voltage regulation during day time operation of solar power plant and random charging profile of electric vehicles. The proposed network is equipped with adaptive protection system to ensure stability and the reliability of the distribution network in the concept of smart grid.

Metal/metal oxide nanostructures based reduced graphene oxide (LrGO-Ag, LrGO-Cu2O, LrGO-Ag-Cu2O) nanocomposites were obtained via green method using Cetraria islandica (L.) Ach. lichen extract. Fourier transform infrared (FTIR) spectroscopy, transmission electron microscopy (TEM), scanning electron microscope energy-dispersive X-ray spectroscopy (SEM–EDX), ultraviolet-visible (UV-Vis) spectroscopy, X-ray diffraction (XRD) and X-ray photoelectron spectroscopy (XPS) were performed to analyze the prepared nanostructures. The results indicated that the nanocomposites were synthesized effectively and Ag-Cu2O nanoparticles with the mean diameter of 27nm were well dispersed on the LrGO. The conversion of methylene blue (MB) to Leuco Methylene Blue (LMB) and 4-Nitrophenol (4- NP) to 4-Aminophenol (4-AP) was performed by biosynthesized catalysts in the presence of NaBH4. The reaction rate of LrGO-Ag-Cu2O nanocomposite during 4-NP and MB reduction was found as 0.0026 s1 and 0.0497 s1, respectively. The LrGO-Ag-Cu2O nanocomposite showed superior catalytic performance for the reduction of both textile dyes.
