HEDNO S.A. was established and launched its operation 2012. [previously: distribution department of PPC S.A] Hellenic DSO that operates as organizationally, functionally independent regulated Company.
Main tasks: Effective Distribution Network operation, maintenance and development throughout the country and the operation of the electricity systems of the non-interconnected islands, as well as the assurance of a transparent and impartial access of all network users constitute the main tasks and the fundamental mission of HEDNO.
HEDNO delivers electricity to 7.4 million customers and in terms of number of consumers served, HEDNO is the fifth largest Distribution Company in EU.
1. Municipalities of Koropi, Lavrio, N. Makri and the interconnected islands of Kea, Andros and Tinos
2. 226,558 Customers at LV and MV and
3. Energy consumption: 956,604 MWh at LV and 480,107 MWh at MV.
4. 3,925 MV/LV Substations of total installed power 808,235 kVA.
5. Voltage regulators in substations
Improvement of the services provided to the customers (WiseHOME App).
Development of new services, by means of the WiseGRID IOP and the WiseGRID Cockpit.
Solutions to efficiently control and integrate RES/DG, cope with voltage problems and increase the hosting capacity.
Intelligent automation in order to improve the power quality and efficiency.
Opportunity to test new functionalities and investigate the replicability in other sections of the distribution network.
Taking into account the ongoing tender for smart meters, the demonstration in the WiseGRID will allow HEDNO to gain valuable experiences.
ICT tools developed in the WiseGRID are a significant step to fulfill this objective of becoming a market facilitator in the distribution network
1. Increase of power quality and RES penetration:
The selection of a congested substation is ideal for testing new advanced application for Grid management and Demand response. The goal is to achieve the increase in RES penetration using grid management tools and demand response.
2. Active demand management for ancillary services and Market Participation
The goal is to demonstrate the role of DSO as market facilitator. Namely combining the DR capabilities and the grid management tools, HEDNO will demonstrate the provision of ancillary services (voltage support).
3. Collaboration with other energy actors:
The goal is to investigate policies that will allow the further increase in the system efficiency through a more holistic view, thus integrating other energy actors.
In this pilot site there will be an emphasis on the following tools & technologies: WG IOP (WiseGRID InterOperable Platform, WG Cockpit, WiseHOME. Besides these, there is also a general interest in: WiseCORP, WiseCOOP, WG RESCO, WG FastV2G, WiseEVP.
NOTE: please note that as the project is developing in a dynamic way, changes are always possible.
1. DMS / SCADA
In many regions, FPIs have appropriate RTUs which relay the fault signals with the se of SMS messages via an integrated GSM modem.
Expected options and services to be provided by DMS (upon complete installation):
2. AMR / AMI
HEDNO is responsible for installing, operating and maintaining the metering equipment necessary for the operation of the Distribution Network. HEDNO collects and validates meter data and provides the respective electricity retailers with the measured consumption data necessary for customer billing.
Smart Electronic Meters at all the customers on MV and limited in LV systems
Responsible for monitoring the transferred energy of these buses every 15 minutes.
AMR communicates with each Smart Meter once every 24 hours using GPRS to collect metering data and meter log files.
Most LV customers are equipped with electromechanical meters which measure active and in certain cases reactive energy consumption.
Approximately 200,000 smart electricity meters with either GSM/GPRS/3G communications or PLC through substation concentrators communications, are expected to be supplied for a pilot rollout to commercial, industrial and residential LV customers. (Delay in the roll out).
3. Meter Data Management System (MDMS)
for validating, storing, processing and analyzing large quantities of metering data.
4. Customer Identification System (CIS)
to cover the functionalities related to customers, the collection of the basic identifying information such as contracts and requests for types of energy products and basic functionalities offering, as well as receive fault complaints from customers.
5. Outage Management System (OMS)
to detect outages within the electric distribution network, as well as outage verification and/or supply restoration.
6. Geographic Information System (GIS)
Originally designed to capture, analyze, manage and present the spatial or geographical network data. It can collaborate with other systems and technologies concerning the network functions and management operations, such as DMS-SCADA, SAP, CIS, etc.
7. Distribution Grid Components
Smart meters, DER Controller, Concentrators
