Denver, CONov 17-19, 2009
Virtual Power Plant Simulator (VPPS)– Changes to existing architecture (if applicable)– Interface implications to legacy systems– Architecture Considerations for Emerging/changing
requirements– Improved Benefits from Architecture Changes
• Overall Project Lessons Learned (3-5 Slides)– Topics could be wide ranging (project planning,
resources, stimulus implications, software integration, hardware installation, customer acceptance, etc.)
– What surprised you? What information would member utilities find interesting?
• Q&A

• Q&A• Models “Load” as Controllable within bounds:Real and Reactive Power
• Looks beyond the station to the end-use and customer
• Considers load as a “resource”, including distributed energy resources, that could be controlled to relieve system constraints
• Considers the distribution system as a potential resource for contingency planning

– What surprised you? What information would member utilities find interesting?
• Q&A• Optimizes resource allocation across power
system• Harmonizes grid operation from end-use to RTO• Enables adoption of renewable and distributed
resources• Permits real time optimization of system under
current operational opportunities and constraints– System constraints– Market value– Environmental constraints
• Simulation prior to mass deployment reduces investment and operational risk

– What surprised you? What information would member utilities find interesting?
• Q&A• Vision of Smart Grid as a Virtual Power Plant appears
technically achievable• Operational requirements and impacts need to be
understood and optimized• Economics and system benefits need to be understood
and quantified to optimize resource allocation• Alignment of vision and public policy is needed to
effectively capture societal benefits• Collaboration between industry, academia, and
government is required• The EPRI/AEP Virtual Power Plant Simulator (e.g.
OpenDSS platform) Smart Grid Project permits stepwise evaluation of the various systems and components of a smart grid, including cross-impact analysis
