Assessment of Flexible Demand Response Business Cases in the Smart GridGerrit Jötten, Anke Weidlich (SAP), Lilia Filipova-Neumann (FZI), Alexander Schuller (KIT)Frankfurt, June 07, 2011
21st International Conference on Electricity Distribution CIRED
Field tested in 25 households in the Netherlands Electricity trading via PowerMatcher protocol Global optimization via market mechanism Local statement of preferences via bids submitted to auctioneer agent
The Bi-Directional Energy Management Interface Approach
Day-ahead tariff profile as load shifting incentive
Field tested in 100 households in Germany Automated optimization of appliance operation No real-time control (extensions for real-time signals planned) Win-win through lower procurement costs and potentially lower tariffs
Field tested in in 10 households in Greece Multi-agent system in which households agree on priorities for load shedding Provision of ancillary services such as load shedding support Provides grid cell islanding and black-start support
Common assumptions Roll-out of smart metering, independently of the business case Usage of existing communication infrastructure (e.g. DSL connection, Wi-Fi,…) Heat-led manageable µCHP units Manageable loads Freezer (runs Ø 8 hours/day with 106 W) Refrigerator (runs Ø 8 hours/day with 140 W) Washing machine (890 Wh per cycle; 141-245 cycles per year) Dryer (2,460 Wh per cycle; 102 cycles per year) Dishwasher (1,190 Wh per cycle; 203 cycles per year) Balancing actions taken in the cluster do not influence overall balancing zone
Balance area of a DSO is considered Balance area for differences (Differenzbilanzkreis) Costs for balancing power in specific balancing zone Avoidance of shortage situations (because they are expensive on average)
SmartHouse/SmartGrid technologies provide business opportunities that have potential to refinance their investments
Initial hardware and IT integration investments must be brought down considerably
Some SmartHouse/SmartGrid technologies can only be applied if the regulatory framework is changed or the availability of data on current grid situations is enhanced
(Real-time) balancing and power supply enhancement are interesting applications for SH/SG technologies
It is less interesting to only focus on procurement cost minimization for an energy retailer
