Title of the presentation: Substation Control System (SCS) outcomes on field and its

integration with actual Operation Center System (OCS)

Abstract of the presentation:

Starting from an overview on system architecture of GRID4EU project DEMO 4, this presentation will

show outcomes coming from SCS installed on field and its interaction with OCS. During monitoring phase,

SCS collects results obtained by regulating distributed electric resources (DER) represented by On-Load Tap

Changers of transformers located in the primary substation, by modulating reactive power of controllable

generators and both active and reactive power of the energy storage system (ESS). In addition, the presence

of a storage system, for which it has established a charge level at the end of a certain time horizon, imposes

an integral constraint to the mathematical problem and requires the availability of load and generation

profiles for the calculation of future periods to implement a dynamic reconfiguration of the storage on MV

network. For fulfilling these goals, OCS has been extended to export in real time to SCS, power grid

schemas, HV/MV measures and states, load/generation forecast data and physical/electrical information.

OCS integration with SCS is completed by the presence of remote HMI’s of primary substation systems for

monitoring the progress of operations and the possibility to enable/disable SCS functionalities in order to

switch to ENEL DER regulator system. Furthermore, this feature will allow a comparison of both DER

regulators results which can be shown in this presentation.

Title of the presentation: LV network supervision


AMI (Advanced Metering Infrastructure) systems based on powerline communications are currently

deployed all over Europe. Powerline, used as a communication channel, can provide additional applications

beyond the mere data transmission such as feeder and phase identification, which can be

considered as a first step for LV network supervision.

But, LV network supervision is a broader concept that comprises additional aspects apart from grid

topology (distributed elements – phase and line). LV Network Supervision also includes commercial losses

(fraud) detection, detection and correction of unbalances, and faults detection in LV lines. The benefits in

terms of LV grid operation are clear. In this presentation we will show how GRID4EU Spanish demo

implement LV Network Supervision in the field, benefitting from the current massive deployment of smart

meters.

Title of the presentation: Findings on collected power quality events in the Swedish demonstrator


Smart meters behave as distributed sensors along the LV lines. They generate a great amount of data that has to be taken care of in order to get useful information that can be used in the operation of the LV grid. The presentation will share the main findings obtained after the analysis of the collected power quality events from the beginning of 2015 of about 10,000 meters located in the Swedish demonstrator of the GRID4EU project.

Partner: SOCOMEC – Demo6 (Carros, France)

Title of the presentation: Experience of islanding of complete LV Grid


Energy storage installed in the LV grid provides wide range of services, including the possibility to supply the complete LV grid during an islanding. This function has been successfully tested during the Nice Grid project using Socomec energy storage

solution SUNSYS PCS². Test conditions and results will be presented.

Title of the presentation: GRID4EU Demo4 Cisco Field Area Network Architecture


Throughout GRID4EU Demo4, Cisco implemented a Field Area Network (FAN) Architecture through the

use of dedicated HW and SW features.

By fact, GRID4EU Demo4 original requirement was to develop a dedicated Secondary Substation interface

to realize back-hauling link using four different telecommunication transportation technologies:

• WiMax

• 3G and 4G

• DPLC

A dedicated modular HW device, CGR 1120 (Cisco Connected Grid Router), has been prototyped and then

industrialized through the project.

Likewise, dedicated SW has been developed by adapting 101 protocol over IP. Moreover the following SW

features have been implemented on field:

• SCADA Gateway (101-104 “translator”)

• 61850 GOOSE protocol transportation on small WAN

Title of the presentation: How can utility owned microgrids been used to provide system services to the

grid?


Being part of the European project GRID4EU, NICE GRID demonstrates in the south of France the way how flexible distributed energy resources (like flexible loads, batteries or prosumers) can contribute to increase the reliability and quality of service of the grid. While flexibilities from residential and industrial customers are aggregated by the retail or sourcing companies, the flexibility needs are predicted by the distribution grid o operator or the transmission grid operator. Distribution grids have become impacted by the deployment of renewables that varies largely from the region and the socio economic footprint. Over constraint grids have patterns that vary during the day, daily and seasonally. This is an important element for the distribution grid operator when defining the boundaries of zones in his grid that need to be optimized against the predicted constraints in his grid. These zones can be understood as dynamic microgrids.



Partner: EDF R&D – GWP4

Title of the presentation: Feedbacks and lessons learned from GRID4EU on standards


The GWP4 (Technology and communication standards) of the GRID4EU project has the following

objectives: to define the most recent standards potentially applicable to the six demonstrations of the project

and to validate the implementation of the appropriate standards and compare these implementations among

the demonstrators. Finally, the GWP4 aims at providing feedbacks and lessons learned during the

demonstrations to the standardization bodies.

During the first year of the project, the GWP4 identified the communication and information standards that

was planned to be used by the 6 demonstrations of the GRID4EU project. The SGAM (Smart Grid

Architecture Model) has been used by the demonstrators to describe their architecture and the standards

they planned to use.

The GWP4 then focused on the testing procedures on the standards performed by the demonstrations and

their partners. These procedures included compliance tests performed by the partners on their products and

software, under laboratory tests, and interoperability tests performed under the context of the

demonstrations.

During the last years of the project, the GWP4 listed the main issues faced by the demonstrations regarding

standards. Two questionnaires were designed to collect their feedbacks through a set of questions and

assertions about standards. To monitor the implementations of the standards by the demonstrations, the

GWP4 focused on the three major standards which was the most widely used by the project: the CIM, the

IEC 61850 and the IEC 104. Some extensions to the IEC 61850 and the CIM has been performed by some

demonstrations and will be forwarded to their respective working groups of the IEC, but for all the

demonstrations, the IEC 104 is still the most widely used standard in terms of substation automation. The

use-cases of the GRDI4EU project will also be forwarded to the recent initiatives of the IEC related to use-

cases methodology and repository, as these GRID4EU use-cases may contain some elements which could

improve the IEC use-cases.
