BEAMS Approach

BEAMS – OGEMA Extension

OGEMA platform basics:

OGEMA is an initiative started by Fraunhofer IWES in November 2009. Two

major goals are:

1. Developing and setting an international standard for a building energy

management gateway middleware

2. Developing, promoting and supporting a reference implementation of this

standard

Both goals are driven by the OGEMA Alliance, which is open for participants

from industry as well as research

BEAMS – Greening Energy Positive Tools EV Integration


•We decide to charge when …

•Energy is cheaper

•There is an excess of energy

•To reach the specified State of Charge is critical

•EVs are not the only devices in the facility

•Energy availability depends on the rest of the loads and sources

•Energy storage availability is not independent from energy charge

from the rest of the loads and sources

Optimizing EV charge

Brussels, 13th December 2012

Batteries are a particular load Energy instead of Power

Q0 = 18 Ah

DQ = 78 Ah

Qd = 90 Ah


10



Central App and CHOP must work together

Central App knows:

PV power availability (and price)

Grid power availability (and price)

Loads (EV not included) features (criticity, power

curve)

Central App triggers an optimization (periodically

or when a change on conditions occurs)

Central App interacts with Chop to integrate EV

charge with the rest of the loads (iteratively)
