EXECUTIVE SUMMARY

Microgrid represents a new network distribution element, which is seen from the grid planning point of view as a sum of several elements present nowadays in the network. These elements are not only demand and distributed generation, but also could include new ones like batteries or electric vehicles with network providing capabilities (V2G).

This sum element is able to synthesize the above mentioned elements in one, the microgrid, with several management options. In any case should be considered as a ‘black box’ where certain demands or contributions arise from/toward the external network distribution, meeting some characteristics and quality standards.

In this way, from the grid planning point of view, the microgrid contributes to elements reduction due to a unique complex sign made from those elements actions.

However, as some different microgrid scenario penetration is considered, this microgrid, moreover is a demonstrative scenario, adds more complexity to the network planning process.

Therefore, it is necessary to define a data model suitable for a convenient capacity and network behaviuor, as well as control algorithms which define its benefits.

In this way, it is needed to define how the microgrid integrates distribution systems, communications, protocols, data models, etc... 

If accurate information were not available, possibly a correct integration with the distribution network could not be planned. This issue could result in a non improving energy efficiency goal as well as quality network and network distribution operation problems.
