3 Key Issues Shaping EMS Implementations Proprietary 3
4 Key Issues Shaping EMS Implementations - High Level - Depletion of global oil, gas, and coal reserves Environmental concerns Population growth and density Terrorism and blackmail Technology advances Changing utility workforce demographics Changing consumer behavior Politics and Economics Proprietary 4
5 Key Issues Shaping EMS Implementations - More Focused - Substantially increased electricity prices Increased deployment of Distributed Energy Resources Renewables Storage Increased deployment of Demand Response solutions Focused, time-limited government funding Increased regulations and standards Improved compute power and software development tools Increased necessity of knowledge transfer Proprietary 5
6 Operational Issues Being Created Proprietary 6
7 Electricity Prices Cost recovery Costs of reducing emissions Costs of modernizing grids Costs of large scale electric vehicle infrastructure Increasing carbon fuel costs Proprietary 7
8 Impacts - Electricity Prices Increasing consumer focus on energy efficiency Smart Grid Dramatically increased volumes of data Infrastructure and tools to enable consumers to reduce their energy costs Increased focus by utilities to deploy renewables and storage Increased focus by utilities on flattening load curve Increased focus on asset management Tracking component age Tracking failure mechanisms Life extension Proprietary 8

12 Impacts Wind and Solar Volatile generation Higher ramp rates than traditional sources More dynamic frequency impact Highly variable output Renewables do not follow traditional generation/load correlation and are weather dependent The higher the penetration of Wind/Solar generation to the grid the greater the need for storage Deploying renewables often requires transmission additions or reinforcements Proprietary 12
13 Storage Battery technologies SC Magnetic Energy Fly wheel Capacitors Compressed air Ice storage Pumped storage Growing Focus in the industry Considered a viable option to store renewable energies Wind production from night to use during the day Riding through clouds Proprietary 13
14 Impacts - Storage Serves as backup during voltage sags and short interruptions New battery technologies possess fast response capabilities, essentially providing square wave outputs Some advanced storage technologies are providing durations in the four to eight hour range, introducing a real potential for electricity production shifting with renewables Technologies are mobile and may be placed almost anywhere Storage technologies have the ability to be scaled. The characteristics of the battery, whether in aggregated in sizes of 10kW or 10MW are the same in each case. Proprietary 14
15 Demand Response A subset of Demand Side Management (DSM) Focuses on peak demand reduction rather than overall efficiency Benefits reliability by reducing demand for power, reducing the demand on supply-side and transmission resources Aimed at both residential and commercial/industrial users Includes load management of electric vehicles Proprietary 15
16 Impacts - Demand Response Communication technologies have made DR dispatchable in timeframes of a few minutes DR is increasingly being classified as non-spinning reserves and used as ancillary services DR is displacing generation deployed as operating reserves and/or regulation Helps maintain grid stability as grid is operated closer to limits and use of unpredictable renewables increases Supports changing the load shape Alternative to peaking generators Typically use IEC communications, but sometimes OPC Proprietary 16
17 Focused, Time-limited Government Funding Explosion of Smart Grid deployments Postponed Transmission and Generation improvements Increased R&D by suppliers Storage Plug-in Hybrid Electric Vehicles (PHEVs) Communications Applications Increased substation automation Increased meshing of distribution grids Proprietary 17
18 Impacts - Focused, Time-limited Government Funding Smart Grid deployments will produce dramatically increased data quantities for operators to deal with Increased investments in historical data storage, asset data (GIS), and real-time business intelligence systems (focused on visualization of temporal and spatial queries) Higher integration between Transmission operations, Distribution operations, and Outage Management Increased use of IP-based communications Increased need for Network Operating Centers (NOCs) Increased PMU deployment Compressed demand for EMS replacements and upgrades Prototype projects will help determine viable solutions Proprietary 18
19 Increased Regulations and Standards Increased deployment of cyber-security NERC CIP Smart Grid communications Shift of control room support costs to NERC CIP compliance Focus on minimizing critical assets within security perimeter Standards Proprietary 19
20 Improved compute power and software development tools Increased CPU speed Makes it possible to deploy extremely compute-intensive applications not deployable in the past Allows for higher frequency execution of real-time sequence Increased use of commercial databases Network communication speeds allow architectures that weren t viable in the past Application to application and application to client Center to Center Software development tools allow development from a higher level of abstraction Increased adherence to standards Proprietary 20
21 Increased necessity of knowledge transfer Aging workforce Less focus on power system engineering background Decades worth of failed efforts to store knowledge in articial intelligence solutions Increased dependence on root cause alarms Increased dependence on situational awareness Proprietary 21
22 Developing and Predicted Solutions Proprietary 22
23 EMS System Changes Transmission Applications Integration with Smart Grid deployments Treatment of Smart Grid as Virtual Power Plant Virtual Power Capture Combination of consumer distributed generation, storage, and demand management to participate in energy markets and grid operations Increased EMS/DMS/OMS/AMI integration Integration of variable generation Severely increased data volumes, much of it stored in historians Storage and communications impacts Increased integration with external Business Intelligence applications Increasingly dynamic load curves Increased deployment of Volt/VAR optimization apps Proprietary 23

27 EMS System Changes Architecture/System Increased integration between EMS, DMS, and OMS systems Improved visualization tools for temporal and spatial correlation of anomalies, losses, etc Ability to share easily with others (e.g. shared screen, capture) Increasingly sophisticated operator station designs Development of applications that computer performance and software development tools wouldn t allow in an economically feasible manner in the past (e.g. TSA) Increased use of Service-Oriented Architecture Decoupled applications within EMS, simpler upgrades Easier integration with non-ems applications Proprietary 27
28 EMS System Changes Architecture/System (cont) Extreme cyber security for critical assets Minimal core within Security Perimeter Improved root-cause alarm packages Faster, two-way, IP-based, secure communications to field devices Increased IED integration Increased Health Monitoring of assets Increased incorporation of CIM Increased platform independence Consider NERC CIP Proprietary 28
