EE distribution scenario 1.
2.
Diffusion of DG from renewable sources. More difficult and costly to manage the distribution grid Increasing targets of quality of service – measured in terms of number and length of outages affecting final customers (both in MV and LV). Directly related to DSO remuneration
What do we need to do to cope with these trends? This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A’s prior written consent.

How to improve the QoS Simple rules to improve the QoS and the efficiency of the distribution are: Identify the less reliable assets of the grid (lines, transformers, etc.) Real-time management standpoint: change the network configuration: to reduce the load of the critical components to move the load where the losses are lower Planning standpoint: pinpoint investments where are really needed Detecting in real-time the presence and the location of a fault to restore the service as soon as possible, e.g.: reconfigure the grid to minimize the no. of disconnected customers send a workforce to fix the problem Keep under control each node of the grid (transformer stations, point of energy delivery at customers’ home, distributed generation) implementing what can be called a real-time integrated monitoring application. Are we able to do that now with the present technology? This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A’s prior written consent.

Today’s distribution grid management Managed with a centralized model from the control center: SCADA: receives measures and alarms from HV/MV substation allow the sending of commands to circuit breakers and disconnectors to alter the topology of the MV grid, e.g. in case of fault Automatic Meter Reading: used for commercial purposes only (CRM, billing, etc.) Little information on MV-LV side of the grid because: get more info. => a widespread communication handle more info. => a less centralized approach The answer to the previous question in NO. Enhance the ICT level of the distribution grid This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A’s prior written consent.

Project Summary INTEGRIS: INTelligent Electrical GRId Sensor communications
THEME: ICT-Energy-2009-1 Grant no. 247938
The goal of the INTEGRIS project is the design and the test of an ICT architecture enabling the Smart Grids that is: 1. heterogeneous, i.e. integrating multiple communication technologies (BPL, wireless), 2. distributed, i.e. enabling the distribution of “intelligence” across the network, 3. open, i.e. underpinned by nonproprietary standards (e.g. IEC 61850, IEC 62056, SNMP…)

Integrated Monitoring The amount of data to handle will increase exponentially and some procedure to optimize the data flow should be considered Measures are stored in a DB distributed all along the grid nodes (SS, PS and CC) Information is processed close to where it is stored Only aggregated values and alarms are brought back to higher level of the grid

Integrated Monitoring The benefit of an integrated grid management will be exploited only if it makes reference to open standards 61850 beyond SAS – all the electrical domain 62056 (DLMS/COSEM) – metering application DLMS/COSEM ↔ 61850 converter is needed at SS level where data from different domains are merged

Further remarks Measures have to be associated with the grid topology to take the right snapshot of its status at a certain time. Present – network is described only in the CC (HV/MV only) INTEGRIS – DBs at PS/SS level contain the info. on a part of the topology
Issue! MV time-variant topology: the hierachical relation between PS-SS changes when the network is reconfigured, e.g. to restore the service This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A’s prior written consent.

Further remarks What “real-time” means in the network monitoring application? “real-times” = time step suited for a specific purpose Present Measures from PS equipments are got each 30 s – 60 s SS and customers measures are not used at all INTEGRIS

Communication architecture
Substations are nodes of an ICT grid equipped with INTEGRIS Devices (IDEV): 1. store information and perform algorithms locally 2. front-end sensors scattered through the grid 3. maintain an efficient communication between themselves and CC This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A’s prior written consent.

Standard BPL technology on LV cables: smart meters ZigBee: LV sensors (LV busbars and lines in SS) Analog front-end for MV sensors (MV busbars and lines in SS and PS) Each sensor is modelled as a 61850 logical node

Unbundling of the Energy Market is supported natively by the architecture: Each operator manage its own system via the same ICT grid DSO ↔ DMS; ICT operator ↔ Network Management System Market/Billing Co. ↔ AMI interface This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A’s prior written consent.
