Big data revolution Case LV Monitoring

Big data revolution Case LV Monitoring Placing data collection, management, analysis and action at the heart of the smart utility Vattenfall Peter Söderström, Asset Development Manager, Vattenfall Distribution

Agenda 1 Vattenfall an overview 2 Building the Smart Grids landscape with Smart Meters 3 Big data for low voltage network monitoring 4 Conclusions

Vattenfall Group in brief The owner s assignment The object for the Company s activities is to generate a market rate of return by operating a commercial energy business that enables the company to be among the leaders in developing environmentally sustainable energy production. One of Europe s largest generator of electricity and one of the largest producers of heat 6.2 million electricity customers, 3.2 million electricity network customers and 1.9 million gas customers 100% owned by the Swedish state with operations mainly in the Nordic countries, Germany, Netherlands and UK Main products: electricity, heat, gas, energy services Business operations: Production, Trading, Distribution, Sales and energy services

Our Vattenfall mission Distribution To continuously improve the reliability and efficiency of our distribution grids to be able to offer our customers sustainable energy solutions. Our vision As the most reliable and most customer focused energy provider we develop smart energy solutions Vattenfall Distribution in numbers Net turnover Investments 18.2 BSEK 4.2 BSEK Transmission 85 TWh Customers ~ 3 200 000

Vattenfall Distribution Sweden More than 10 years of experience of Smart Meters Smart Meter roll-out business case revised Smart Meter roll-out starts Smart Meter roll-out finished Hourly metering for all customers 2003 2009 2015 The Electricity Act: Demands monthly billing for all customers until 2009 2006 EU DIRECTIVE 2009/72/EC Demanding 80% intelligent Metering Systems by 2020 for all cases being assessed positively 2012 EU DIRECTIVE 2006/32/EC demanding meters that reflect [ ] actual energy consumption and [ ] information on actual time of use The Electricity Act: Hourly metering for customers

The roll-out was executed in 3 stages in Sweden with 860,000 Smart Meters successfully installed over a five year period AMR 3 Telvent/Echelon (2006-2008) 600 000 meters AMR 1 Actaris (2003-2006) 110 000 meters AMR 2 Iskraemeco (2004-2006) 150 000 meters

Smart metering has already enabled process improvements Faster customer interaction, reduced lead times Better power quality analysis Faster and cheaper customer moves Improved monitoring of the Grid Operation

Smart Meters and Data Management are important roles of the DSO It will also require reconsidering of the role of DSOs. In particular it needs to be ensured that their regulated activities are limited to tasks which are best performed by a natural monopoly and that new services made possible by new technologies are developed in competitive markets. EC communication on internal energy market Cost effective and uniform roll-out for society Market transparency and improved services for customers Improved business processes, better network utilization and increased safety for DSO

Case: Why do we need to monitor the low voltage network? Increased monitoring of the low voltage network is a necessary next step to improve our customer service The low voltage network is 50% of our total network and is not monitored through traditional network operation Regulative pressure on reliability requires outage management improvements in the whole network Especially for conditions with multiple (weather related) faults in a limited area

Case: What about big data and requirements? Around 1 million event per day! Many event types and varying importance, for example: Power quality (voltage) Communication Outage 1 phase and 3 phases Zero conductor fault Reverse energy Low latency Reliable data Integration with customer, network and SCADA information Useful information that the operator can act upon

Case: With Smart Meters and analytics the last 50% of the network can be monitoried

Case: What about monitoring in secondary substations? Intelligence in secondary substation is an important supplement in more complex situation where monitoring is combined with control (Voltage/VAR) Preliminary development results show that at least 50% of the secondary substations should benefit from monitoring Challenge; is the secondary substation monitoring an extension of the SCADA system or the AMM system? - Both solutions appears viable - Cost and benefit of scale - Will be a key issue in the initiating second roll-out of Smart Meters

Conclusions Smart Meters are required to enable market access and transparency for the customer, and is also an important tool for process and service improvements by the DSO Millions of events from individual Smart Meters most be combined with network and customer information to transform data into information that can be acted upon Using Big Data and analytics a 100% monitoring of the network is a reality enabling clear, efficient and non-ambiguous service to each individual customer
