Cluster Overview • Cluster focuses on the distribution system and the end load • Adding more renewable, but less controllable generation, will require more participation by the electric load – Distributed generation may be embedded in “demand” – Demand could drastically change with new loads – New loads can have unexpected societal impacts • New distribution technologies promise better reliability – Cyber security of distributed devices is a growing concern | 3
Cluster Problem Areas • Focus on issues associated with making the distribution system and load more known and/or controllable • Directly addresses many of the core issues associated with the “smart grid” 1 Transm issionBus 138 kV 1.00 pu – Traditionally, distribution 1.050 tap 1.050 tap A A 3.3 M W 3.2 M W MVA MVA -2.0 M var -1.6 M var 13.8 kV 3 2 and load have been viewed 1.060 pu 1.063 pu A A M VA MVA 1.060 pu 1.064 pu as relatively passive A 1.062 pu A 1.067 pu VA M MVA – Key smart grid premise is to A A VA M MVA 1.067 pu 1.062 pu A A make customers participants, VA M 1.069 pu 1.064 pu 1.064 pu 1.070 pu MVA A A M VA MVA providing information to help them optimize their electricity usage – Making the distribution and demand more “active” adds cyber security issues | 4
Cluster Approach • Objective of the cluster is to better determine and solve the cyber security issues related to making for a more active distribution system and demand • Distribution Network Thread – Growing number of cyber enabled distribution system devices makes password management problematic • Active Demand Management Thread – As the load becomes more active, and potentially mobile, new opportunities and challenges are emerging | 5
Activity Highlights • Password Changing Protocol • Large number of distributed devices make password management difficult; activity is investigating the use of authenticated hand held devices that then communicate securely to the pole mounted devices • Development of the Information Layer for the V2G Framework Implementation • Loss of fuel tax revenue is a key concern with a transition to electric vehicles (EVs); looking at security aspects of mileage-based tax collection using GPS systems | 6
Activity Highlights • Trustworthy Framework for Mobile Smart Meters • Idea is meter is on EV with reporting to utility of amount charged, and utility providing the EV with pricing options; work is progressing on development of a basic obstacle- aware routing protocol • Control of distributed reactive resources • Distributed devices like EVs and PVs can provide reactive power; algorithms needed to determine the amount of information necessary to determine the appropriate power factor | 7
Cluster Impact • Demonstration of the password changing framework between a laptop and an android phone to test performance • Specification of a basic reliable routing protocol titled Obstacle- Aware Cyber-Physical Routing for Vehicle-to-Infrastructure Communication • Assessment of past mileage-based data usage projects • Development of a localized control scheme to achieve a target household power factor using smart meters and a home monitoring and control system | 8
Planned Research for Coming Year • Explore camera based authentication protocols. • Continue the assessment of previous EV studies, and develop a set of key requirements for the architecture and the data collection/processing aspects • Study the issues of reliable and secure communication and routing over heterogeneous networks (WiFi/cellular/ZigBee) • Move towards validation on distributed reactive resource control algorithms on the UIUC distribution network | 9
