Modeling, simulation, and experimental verification of a smart grid system

Due to the concern over the depletion of conventional fuels and increasing environmental awareness, creating a smarter grid has gained more significance and has been alluring a wide range of industrial and academic stakeholders. One of the main features of a smart grid (SG) system is being a fully observable and controllable infrastructure from generation to the consumption of electricity among other features. A SG didactic system developed by the De Lorenzo company is utilized for this study. The didactic system is used as it serves measurements at all buses and includes diverse power grid units and devices to be used for the analysis of the system. A MATLAB/Simulink model is obtained pertaining to a SG system with generation units, transformers, transmission lines, loads, measurement devices, compensation units, and so on. Along with the modeling of each subsystem of the SG, the developed model is validated by the experiments on the real system, and also the system performance is analyzed. The SG model is validated step by step on the real test system with errors ranging from 0 to 10.03%. Hence, it has been proven that the model is able to be applied to an enlarged system and to be used for test and experimental studies of new types of equipment and educational purposes without depending on the physical system.
