SMART GRIDS PROJECTS IN EUROPE – THE BIG PICTURE

• More than 450 projects – 221 ongoing

• 578 Implementation sites • 1750 Organisations

• Good degree of application diversity • Smart network management and

smart consumers/homes are the most targeted

• New control/automation system consolidated

• Distributed ICT for DER/flexibility

SMART GRIDS PROJECTS IN EUROPE – THE BIG PICTURE

• Density of implementatiion sites weighed by budget

• EU 15 concentrated most of the activity

• Some interest on East side but small budget allocation

SMART GRIDS LANDSCAPE

•Projects not evenly distributed (EU15 doing most of the job)

•Many projects focus on integration of technologies and applications

•Fundamental role of the DSOs / TSOs

•Deployment cover most of investments (7% of projects – 60% of investments)

LARGE SCALE MULTIDISCIPLINARY DEMONSTRATORS

•Large scale demonstrators, involving high number of sites and communities needed to prove up-scaling and reliability of solutions

• Incresaed complexity of electricity system requires multidisciplinary consortia to integrate competences and share risks

SET UP OF MARKET PLATFORMS FOR THE PROVISION OF SERVICES

•Revise incentives model to accelerate innovation uptake and encourage to move towards a service-based business model

•Most of smart grids benefits are systemic in nature – service-based market platforms are essential to attract operators

EUROPE: LESSONS LEARNED

CONSUMERS

• Need to have trust to harvest benefits from smart grids technologies and applications;

• Consumer engagement is crutial to development of electricity services platforms;

• Consumer segmentation is very important to taylor energy services, target early adopters, guarantee different levels of engagement.

INTEROPERABILITY, DATA PROTECTION AND DATA SECURITY

• Open and secure ICT infrastruture is core for smart grids implementations;

• Convergence towards IP communications and other standard-based solutions;

• Energy and ICT communities need to work together to coordinate security measures, avoiding blind spots;

• Data protection and security not yet sufficiently addressed by the projects. Experience from other sectors is needed. Privacy-by-design approach

Reliability

Automated feeder switching:

•Reduction of frequency of outages, number of customers affected by sustained outages and momentary interruptions, total amount of time without power

Automatic control

VVO: Voltage and VAR control Optimization:

•Reduction of line losses by 5-10%;

•Peak demand reduction by 1-2.5%.

Advanced Metering Infrastructure

•Cost reductions and productivity improvements related to reductions in labor and vehicle costs;

•Less problems between systems and customers for projects with preceding experience in smart meter deployment.

Demand

•Demand reductions from the application of Advanced Metering Infrastructure, pricing programs and customer-based systems.

Motivations of the good results in network and SG development

RES:

•Acceleration of SG development to efficiently connect renewable powered electricity into the grid.

Timing:

•Advantage of building Smart Grid technology into transmission infrastructure from the outset.

Regulation:

•Facilitation of regulatory systems due to enormous size of state-owned transmission companies.

Economy of scale:

•Economy of scale that helps to reduce costs and spark domestic manufacturing of Smart Grid equipment.

Government support:

•Support of the government to efforts of domestic and foreign Smart Grid manufacturers through subsidies, R&D funding and major lines of credit.

CONCLUSIONS

Prominence

• in each country SG vital part in government strategy to achieve common goals of energy security and low carbon economic growth

Smart meters

• first measures used and deployed: present deployment level depends on development stage of the country

T&D control needs

• similarities in T&D control needs between more and less developed countries in integrating interconnections and distribution network for upgraded or new plants and lines

Advancement

• Japan and South Korea most advanced in SG development thanks to good performance of electricity systems, thus devoting efforts to customer side applications

Government support

• need for governments to put strong efforts and investments in development of SG applications, and mainly in demonstration projects, and that local authorities support start of initiatives
