Development of Rule-Based Control Algorithm for DC Charging Stations and Simulation Results

The rapid increase in electrical appliances and systems today means an increasing load on the main power grid. This rising will increase much faster in the near future, since especially electric vehicle load can create a local or global peak load on the grid. This will cause power quality problems such as frequency or voltage instabilities on the main power grid. However, topologies that will reduce the load that the electric vehicle will create on the grid have been suggested by researchers recently. To solve this problem, it is recommended to use the batteries of electric vehicles connected to the grid. In this context, the operation of V2G (Vehicle-to-Grid), V2H (Vehicle-to-Home) or V2V (Vehicle-to-Vehicle) topologies using vehicle batteries has begun to be seen as an opportunity. The most critical issue in the operation of these topologies is to control the energy flow in a coordinated manner, considering the losses. For this reason, a smart charge control algorithm is needed for the operation of this charge topologies. In this study, a rule-based control algorithm has been developed for these topologies, which also considering user satisfaction. This developed algorithm was simulated in real time according to a scenario prepared in the Matlab/Simulink program and the results were analyzed.
