2 Introduction Ryan Sims Todays landscape and drivers Intro to Active Network Management The Orkney Smart Grid Lessons learned How is this applicable to you Jeremiah Miller 2

3 TodayÊs Landscape and Drivers Uncontrolled peak load growth Intermittent renewables Frequent extreme weather events N-1, planning for the worst Limited control Changing business models Limited visibility Regulatory change Unused latent grid capacity One thing is for sure -business as usual is not an option New electrical loads Utility death spiral 3

4 Active Network Management (ANM) Increased Visibility Inform Decisions with Data Actively Manage Worst Case Scenarios Increase Grid Capacity Avoid/Defer Infrastructure Upgrades Reduce System Cost Historical Capacity Capacity Achievable with ANM 4

5 Problems ANM Solves Area Substation SCADA / DMS (Control Room) Area Substation Enterprise ANM Application ANM Controller Generator Distribution Network Management in a world of increasing Energy Storage System Distributed, Intermittent Energy Resources, Demand Response, Islanded Networks and Microgrids Generator Substation Controller ANM incorporates Energy Storage System end-to to-end, autonomous distributed control solutions in continuous field operation Transitioning from Passive to Active Networks

6 Typical Problems Across the Voltage Levels Transmission Network Distribution Network Utility ESS Grid Supply Point Thermal congestion on distribution or transmission assets. Voltage rise and step change Providing voltage support and other responses to the TSO Generation Primary Community ESS Substation Thermal congestion Reverse power flows Voltage rise Generation LV Network Micro-generation Demand Generation Local Voltage rise Increased intermittent DG

7 What Makes ANM Solutions Useful? Active Network Management s ROI Massive increase in grid hosting capacity: % Avoiding or deferring grid upgrades: enhanced assets ANM is a distributed, end-to-end autonomous control solutions for DER integration ANM bridges protection systems and SCADA Increased visibility and ANM is scalable: Device control at PCC Substation control of multiple DER Enterprise control of multiple substations Open standards based integration to EMS/DMS and field devices Streamlined DER interconnection with reduced costs: Increase grid asset utilization

8 The Orkney Smart Grid Islands off North of Scotland Scara Brae Scapa Whisky >50% Wind Capacity Factor

9 The Challenge Local utility seeking cost-effective alternative to grid upgrades to provide connections for new renewable generators: network already at full capacity Avoid costly grid upgrades Increase capacity for renewables Facilitate interconnection of more community wind Limited export capacity to bulk power system Subsea cables have combined capacity of 40MW Local demand varies from 8 to 32MW 9

10 The Solution Active Network Management Non-firm actively managed grid connections for Distributed Generation Real Time Ratings Energy Storage System Maximize use of latent capacities Monitor real time capacity of grid Reduce distributed generation output when grid is under stress Enterprise ANM Controller 10

14 Some Suggestions for You and Your Coop 1. Consider alternatives to grid reinforcement Increasing asset utilization & increasing DG interconnection Minimize grid modernization costs to entire co-op membership 2. Invest in Information and Communication Technologies ahead of need build a scalable platform The future of the grid depends on data networking and connectivity 3. Start building more flexibility into the organisation that plan and operate the grid New skills/jobs, New regulation: See RIIO in the UK and REV in New York State 4. Incrementally adopt smart solutions See the work of the UK Smart Grid Forum

15 Conclusions The way we plan and operate the power grid is changing New solutions exist to provide more cost effective solutions for distributed and renewable generation integration: can represent a massive increase in DG interconnection ANM is an emerging part of the grid management space E.g. defer reinforcement while still increasing grid hosting capacity support Co-op member DG deployments E.g. increase utilization of existing grid assets manage total member grid costs Issues associated with renewables integration, microgrids, EMS/DMS deployment, resilience and increasing data dependency are common to the UK, EU, USA and Canada The drivers are common across international projects, but the adoption behavior is driven by local regimes Lessons are being learned elsewhere, this learning needs to be visible and accessible Thank You 15
