Hybrid Electric Vehicles and Smart Grid

Overview

One of the main goals of the project is to model the electric demand of Plug-in Hybrid Electric Vehicles (PHEVs) and Electric Vehicles (EVs) and to find out, if the underlying electricity network can support such demand.

For doing this, MATSim has been coupled with a simulation model of the electricity network, which is called PHEV Management and Power System Simulation (PMPSS) [1]. Furthermore a charging module was added to MATSim, which decides the policy, when and how charging is performed by the vehicles. After relaxation of the MATSim Iterations, the charging information is given to PMPSS which finds out, if certain grid constraints have been violated (e.g. transformer capacities). This information is given back to MATSim and the charging module. As such, MATSim and PMPSS form an outer loop around the original MATSim loop.

Three type of charging schemes have been implemented in [1]: Dumb Charging, Dual Tariff Charging and Smart Charging. They are shortly described in the PDF poster, here.

Developer Infos

• The energy consumption of vehicles is calculated based on the average speed they drive along a link. Event handlers are used to capture this information.
• Controller listeners are used to implement the charging module and the scoring, which happens after the simulation.
• As PMPSS is implemented in MATLAB, it is invoked from Java after a specified number of iterations, where the MATSim demand is assumed to be relaxed (e.g. 100 iterations).
