MetroHESS research project is structured into several Work Packages for management reasons. Initially, measurements in traction rectifier and substations and in the traction systems on board train as well as energy auditing in selected stations of the Athens Metro network will be carried out. The results of the measurements will form the basis for the design of the Hybrid Energy Storage System (HESS), while appropriate energy management strategies will be developed.
After the design and pre-dimensioning of system variants, the architecture of HESS will come next, including system functionality control, cost-benefit analysis, feasibility study.
Then the preselected variants will be further analyzed through simulations / mathematical models in order to precisely determine their technical behavior along with the selection of their optimal combination. Algorithm results will follow the basic architecture of the system, including the design of all parts of hardware/interface design/ appropriate adaptation of power electronics.
Throughout project lifetime, dissemination and publicity actions will be implemented. Purpose of the dissemination strategy is not only to make the project more widely known, but also, to ensure as many stakeholders’ involvement as possible to achieve project transferability. The designed HESS will be evaluated for its efficiency and economic feasibility and prior to that a SWOT analysis, business case and exploitation plan will be elaborated.
The innovation of the project is based on the fact that no general model approaches will be formulated; on the contrary, the project will exploit primary real energy data that will be collected during energy measurements.
