1 1 Advanced Power Electronics Systems Enable Utility Industry Transformation Wanda Reder IEEE Fellow, Member NAE S&C Electric Company - Chief Strategy Officer, Wanda.reder@sandc.com November 9, 2017

2 2 Overview Grid trends and drivers Modern grid changes how we: Make it Move it Use it Future grid examples Opportunities remain

3 S&C Delivers Solutions 3

4 4 Grid Trends and Drivers Growing Expectations for Reliability Aging infrastructure is prone to failure Increasing Environmental Requirements Escalating Security Concerns Increasing Climatic Vulnerability

5 Changes How We Make Energy: More distributed supply Accommodate growth Move Energy: Flexible, intelligent, resilient Better reliability, visibility Use Energy: Integrate end-use activity Empower customers Innovation: Energy storage Power electronics Distributed intelligence Adaptive protection Layered architecture Self-diagnostic, healing Data, cyber, analytics Source: IEEE GridVision 2050

6 Changes how we Make It US Solar in 2016: Cost drops to ~$1.50 / Watt Nearly 15,000 MW added Utilities are installing it Top choice for new generation A new MW every 36 minutes

7 Changes how we Move It Integrated Old Grid Grid 2017 S&C Electric Company, Inc. All rights reserved.

8 Evolving Control Architecture Multi-directional power flow DER inter-connections Dynamic operations System balancing Microgrids Voltage swings

9 The Need for Speed Distributed Intelligence Centralized Control IntelliRupter Fault Interruption Uniterruptible Power Supply Communication-Enhanced Coordination Frequency Control Energy Storage (grid-scale & CES) Self-Healing Grid Reconfiguration Active Network Management Distribution Management System Volt/VAR Control Outage Management System Geospatial Information System Advanced Metering Infrastructure Time - seconds

10 Distributed Intelligence is Key IntelliRupter PulseCloser Interrupt fault current Segments load Two-way sensing Adaptive protection Detects power quality events Reliability + reduced labor + future proof

11 Merchant 11 Move It With A New Business Model Market Owner-Developer Suppliers Community Large Customers 4.2 MW solar plant with 7 MW energy storage: Minster, Ohio USA

12 12 Changes How we Use It Structural efficiency Energy efficiency Water efficiency Waste efficiency

13 13 Microgrid Advantages 1. Greater reliability and resiliency 2. Greener power 3. Modernized infrastructure 4. Increased security 5. Cost savings 6. Local engagement The traditional utility model integrates microgrids

14 Microgrid: Santa Rita Jail, California

15 ONCOR Microgrid Utilized distributed generation Two solar photovoltaic arrays One micro-turbine Two energy storage units Four generators Four interconnected micro-grids Energy storage is the backbone 15

16 16 Tests renewables + automation + battery storage Ameren Microgrid 1,475 kw connected to grid Wind: 100 kw Solar: 125 kw Natural Gas: 1,000 kw Storage: 250 kw Military-grade cybersecure controller Ameren Microgid Champaign, Illinois

17 Storage is Important Synchronize sources Smooth transition to/from utility source Manage intermittency Energy Storage - Solar Hybrid Project Minimize reverse power flow, maintain voltage Store output and release coincidental with load Energy Storage Wind Hybrid Project 17

18 Many Implications 18 Increased pace of change More dynamics, complexity, integration Reliability (really) matters Changing distribution functionality New worries voltage swings, harmonics, security Architect for the future Energy Financial Services Bulk Power System Energy Provider Customer Distribution Operations Energy Related Services Energy Device Firms Processes and coordination needed

19 Exponential Technology Change But, how fast can WE change?
