IDE4L is a European FP7 project aiming

at developing the concept, the

architecture and the applications of the

new automation for active distribution

grids. The outcomes of the first year of

the Project are the automation concept

and a method for developing the

automation architecture. This method is

based on the collection of the IDE4L

automation functionalities in the form

of Use Case, whose first synthesis yields

the draft architecture, in terms of

actors, functions and information

exchange, together with their sequence

diagram in terms of fundamental steps.

The steps for the implementation of the architecture are:

• Construction of semantic model and physical diagram of

the architecture, consistent with draft SGAM architecture

• Mapping of IDE4L functionalities onto IEC 61850 logical

nodes and communications, and Common Interface Model

(CIM) classes, and

• Definition of type and requirements of information

exchanged between actors.

The adoption of the communication standards satisfies the

automation requirements device-independently. The

definition of interfaces and communication protocols relies

on the specifications of the information exchanged.

The IDE4L automation

architecture includes the

following key actors:

• Substation Automation

Unit (SAU). It receives the

measurements from IEDs and

performs: estimation and

forecast of the state of the

system, voltage and power

control actions, coordination

of procedures for fault

location, isolation and service

restoration (FLISR).

Main features of IDE4L automation architecture

This draft is then detailed according to the SGAM framework layers of the architecture, namely components, functions, communication,

information and business. The implementation of the architecture in the second year of the project is realized using existing technologies and

standards, and accommodates the newly developed IDE4L applications. Testing ad validation phase comprises numerical testing of the algorithms,

integration testing of architecture and equipment, field demonstrations in the distribution networks of partner DSOs

IDE4l Architecture semantic model

• Distribution Management System (DMS). It coordinates the power control strategies of the SAUs and when necessary buys ancillary

services from the Commercial Aggregator.

• Commercial Aggregator. It buys and sells energy and flexibility services of the distributed energy resources belonging to a certain regional

area in the electrical market.

MicroGrid Central Controller (MGCC). It manages the grid connection status of an autonomous electrical area in case of faults. In islanding, it

controls the distributed generation in the microgrid.
