Work Package D : "Development of  Emergency Functions"


Work Package Leader : INESC-Porto

Partners involved :  ICCS, SMA, UMIST, EPRI, EDF

Objectives :

The main objective of this WP is to develop the control strategies that will be adopted in the MicroGrid when the systems becomes isolated or has to deal with a local Black Start situation.

When failures occur in the MV or HV system, the distribution network may break into isolated “islands”, each of which must be supplied by itself. With an intelligent distributed approach where the micro controllers (MC and LC) will act, in a very fast way, as independent agents and making an efficient use of the local resources, it will be possible to maintain system operation in an islanding condition.

If a black out takes place, a local black start will be tried, exploiting the communication capabilities and a centralized approach housed in the MicroGrid Central Controller, together with control rules embedded in the local controllers.

These Black Start functions contribute to assure an important advantage for power system operation in terms of reliability as a result from the presence of a very large amount of dispersed generation.
