Benefits:

Integrate renewable energy resources;

Reduce the electricity bill, and the dependence to electricity market;

Supply ancillary services such as demand response, voltage support.

Facility the breaking energy recovery (DC);

Problem:

Increase the frequency of several high-speed trains

Some substations approach the power limit

Voltage drop along the catenary (DC) is important

Solutions:

Construction of new substations;

Reinforce the power supply;

Hybridization.

- Strategies -

Long-term strategy (linear programming)

Minimize the electricity bill, considering

Electricity price in the wholesale market

Forecast of wind power

Short-term strategy (Fuzzy logic)

Limit the overtaking power,

Take full advantage of the local production,

Guarantee life-span of the battery,

SoC of the battery

Real-time forecast of wind power

« Results »



Sizing results

Railway power substation

Subscribed power: 80MW

Hybrid railway power substation

Subscribed power: 40MW

Wind power: 11 × 1.67MW

Battery: 3 × 66kW/100kWh

CONIFER: Project of SNCF, which develops an optimal program to size hybrid railway power station.

SARRY: on LGV (high-speed line LN1)

SARRY



Simulation results

Simulation results of one

typical day

The wind power is

100% used

The SoC is limited no

less than 30% to obtain

a better life-span



Results

Reduction on electricity bill:

4.09 k€ / day

~ 9%

Reduction in grid cost

1,08 k€ / day

~ 32%

Due to a lower optimised

subscribed power

« Conclusions and perspectives »



Conclusions and perspectives

The work has been finished:• Sizing of the hybrid railway power substation

• Modelling, representation and simulation of hybrid railway power substation

The work for the near future:• Hardware-in-the-loop tests to verify the effectiveness of the proposed method

• Experimental tests at EDF Concept Grid
