Interface Implications to Legacy Systems The Virtual Power Plant Simulator • 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 • 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?

Improved Benefits from Architecture Changes • 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 • 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?

Overall Project Lessons Learned • 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 • 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?
