WP1 – Operational Requirements and Needs

The main objectives are the following:

* To assess and identify critical economic and regulatory factors impacting on energy efficiency,

* To generate a baseline inventory of energy requirements

* To define clear measurable Key Performance Indicators and standardised duty cycles

* To define a operational testing framework. This will be used as input for the final testing under a set of operationally relevant test cases.

WP2 – Energy Simulation and Optimisation Tool and its Impact on the Thermal Analysis

* To develop a holistic model framework with clear characterisation of interfaces to sub-systems and commercial multi–train simulation tools for the overall modelling of energy flow and consumption in a complete urban rail system. The model (the OSIRIS tool) will include all the primary parameters that influence energy consumption, as well as their inter-dependencies. The simulation will be based on different physical domains such as electrical, thermal and mechanical energy. Thermal simulation is relating to an optimum relationship between energy efficiency, HVAC usage and passenger comfort.

* To set up the model framework as a basis for detailed modelling and calculations in the technology related WP’s and for the development of decision support instruments. Additionally, it should be used to evaluate the benefits of new technologies – operationally and strategically. Furthermore, the model framework can be used to forecast the energy demand in an urban rail system during operation utilizing commercial multi–train simulation tools.

* To identify efficient and reconciled strategies for realising low energy consuming urban rail systems, by employing optimisation methodologies in conjunction with the Holistic Energy Model.

WP3 – Energy Efficient Vehicle Related Technologies

Within this project it is proposed to evaluate the impact of the following operational vehicle related technologies (installed onboard of urban rail vehicles) on the overall energy consumption and possible energy savings as well as on infrastructure requirements and layout, costs and other operational and economical aspects:

WP4 – Energy Efficient Infrastructure related Technologies

This work-package aims to evaluate the impact on energy saving and CO2 emission of infrastructure recovery technologies in mass transit systems (i.e. LRV, Subway, Suburban systems). To this aim an Eco-design approach will be adopted and to minimize the environmental impacts of the introduction of new technologies in the whole system lifecycle (i.e. possible hazards introduced by batteries).

The above defined objectives will be reached realizing different technical solutions. The technical objectives will be in the electric and thermal domain.

WP5 – Operational Technologies for Reduced Energy Consumption

Operators usually seek to reach “top-down” energy savings objectives through “bottom-up” measures from traction and infrastructure domains. This WP proposes to explore energy saving opportunities in improved operations of existing equipment, including through optimized train scheduling, efficient driving, efficient train pool management, and power demand management.

The approaches defined here deal with command and control systems and their algorithms for the most part, and thus they should be relatively light in investment. Due the intrinsically local nature of operations, the implementation of these approaches will require customizing to the needs of operator. For the same reason, the approaches proposed here have been overlooked by industrial actors and thus, they deserve to be studied in a precompetitive research setting.

WP6 – Validation and Demonstration

* To benchmark Key Performance Indicators, before and after the implementation of energy-efficient solutions;

* To assist in model development and validation through the acquisition of relevant data from each of the three transport modes covered by the project (the ‘Use Cases’);

* To measure energy consumption before (baseline) and after (improved) the implementation of new technologies or improved operating modes, as well as all the environmental factors which affect consumption;

* As with energy consumption above, to measure baseline and improved thermal conditions;

* To capitalise on the statistical data operators have collected before this project, and on any relevant energy conservation experiments they may have conducted.

* To calculate the Key Performance Indices, applying the definitions defined in WP1.

WP7 – Integration and Strategic Assessment
