Outline of Work

• Research Commenced May 1, 2010• Research Personnel (to date):

– Dr. Tomas Yebra Vega (Post-Doctoral Fellow)– Mr. Mayassam Amiri (M.Sc. Scholar)

• Research Projects/Activities:– Modelling of Distributed Loads in a Microgrid on EMT

programs• Incorporation of electric/hybrid Vehicle charging (statistical aspect)

– Modelling of Stability Issues in Microgrid resulting from distributed generation/loads

– Towards Development of microgrid benchmarks models

Modelling of Distributed Loads in a Microgrid on EMT Programs (I)

• Objectives of the activity:– New stochastic model of electric vehicle.– New algorithm for charger that has a lower impact

in the distribution network. Battery model

Modelling of Distributed Loads in a Microgrid on EMT Programs (II)

• Objectives of the activity:– New index (indices) for evaluating the impact of electric vehicle in the network, penalizing

overloading of feeders and poor power quality.– Impact of different charging regimes - grid to car only or bidirectional - car to grid and grid

to car• Proposed Impact of this modelling:

– operation of microgrid to improve its performance (collaboration with Theme 1).– Development of protection system to reduce the number failures in power devices and

loads. Generation of stochastic values (collaboration with Themes 1 and 3).

Modelling of Stability Issues in Microgrids

• Objectives of the activity.– New stochastic models of DGs for transient stability studies.– New stochastic models of distribution networks for transient

stability studies.– New indices for evaluation and comparison of transient

stability studies.
