Mobile Energy Resources in Grids of Electricity

Electric power systems are facing a major new challenge (and hence opportunity): future massive integration in the electric grid of electric plug-in vehicles (EV). Distribution and transmission grids and power system architectures still follow planning rules and procedures defined for the traditional operational paradigm. Therefore, it is necessary to identify and prepare solutions for the operational problems that will be caused on the electric grid, to the generation sub-system and to its commercial operation as a result of progressively increasing deployment of EV. The conceptual approach in this project involves the development of a methodology consisting of two synergetic pathways: - Development of a management and control concept that will facilitate the actual transition – the MERGE concept; - Development of an evaluation suite that consists of methods and programs of modeling, analysis, and optimization of electric networks into which electric vehicles and their charging infrastructure is integrated. The MERGE concept is inspired from consideration of DER deployment but differs in that we consider now the resources to be mobile in terms of their connection to the grid. Analogies will be derived and adapted to the case of mobile resources, which can be either consumers (when in charging mode) or injectors of power (if batteries are delivering power back to the grid). By exploiting a specific computational evaluation suite that is capable of simulating real world power systems (generation, transmission and distribution) for either steady state or dynamic behavior it will be possible to test the adequacy of EV preliminary smart control interfaces that will be developed in the project. It will address comprehensively the impact of EV presence regarding steady state operation, intermittent RES integration, system stability and dynamic behavior, system restoration, regulatory aspects and market arrangements.
