Possible Future DSO Models and Their Implications for T-D Interface Coordination Lorenzo Kristov, Ph.D. Principal, Market & Infrastructure Policy More Than Smart T-D Working Group, November 2, 2017

Increasing DER volume and diversity requires a new T-D interface coordination framework. Area of Activity Challenges of High DER What’s Needed System operations Diverse DER behaviors & energy flows, esp. with aggregated virtual resources Hard to forecast impacts at T-D interfaces DO is not informed of DER wholesale market transactions Multi-use DER may receive conflicting dispatches/signals (from DO and ISO) Distribution grid real-time visibility Real-time forecasting of DER impact at each T-D substation Coordination procedures between ISO, DO and DER provider re wholesale DER dispatches Dispatch priority re multiple use applications (MUA) T & D infrastructure planning Long-term forecasting of DER growth & impacts on load (energy, peak, profile) Assess DER to offset T&D upgrades Distribution grid modernization needs Align processes for T&D planning and long-term forecasting Specify required performance for DER to function as grid assets Modernize grid in logical stages for “no regrets” investment System reliability & resilience High DER may make traditional top-down paradigm obsolete Develop new models to “layer” responsibilities for reliability Market & regulatory issues: Wholesale v retail Monopoly v competition Complexity of central dispatch of high DER volume in wholesale market Unclear boundary between competitive v. utility services, while utilities & insurgents pursue new business models Explore “Total DSO” aggregation of DER for wholesale market transactions Redefine scope of regulated distribution utility with high DER

The design of T-D interface coordination for high DER is inseparable from design of the future DSO. Bookend A: Current Path or “Minimal DSO” DSO maintains current distribution utility mission – reliable distribution service – enhanced only to ensure reliability with high DER volumes Large numbers of DER are centrally optimized in ISO market DER engage in “multiple-use applications” (MUA) providing services to end-use customers, DSO and wholesale market Bookend B: “Total DSO” DSO expands its role to include DER aggregation for wholesale market participation Optimizing local DER to provide wholesale market services Balancing supply-demand locally Managing DER variability to minimize impacts at T-D interface Potential to operate distribution-level transactive markets DSO provides a single aggregated bid to ISO at each T-D interface MUA are simplified, dispatch conflicts eliminated, because DSO is responsible for response to ISO dispatches

“Minimal DSO” retains traditional primary DO mission – reliable operation & planning – with high DER. ISO directly integrates all DER for both transmission and distribution system operations. Requires ISO to incorporate distribution grid network model, have real-time distribution grid state information, and coordinate operations with DSO. This approach has significant complexity, security & scaling risks

“Total DSO” – similar to an ISO at distribution level – is the most robust & scalable model for high DER. DSO directly integrates all DER for Local Distribution Area for each T-D Interface (e.g., LMP pricing node) and coordinates T-D interchange with TSO, so that ISO sees only a single resource at each T-D interface and does not need visibility to DER. DSO manages all intra-distribution area transactions, schedules and energy flows. DSO coordinates a single aggregation of all DER at each T-D interface

The choice of DSO model implicates several key power system design elements. Minimal DSO Total DSO Market structure Central market optimization by ISO with large numbers of participating DER DSO optimizes local markets at each T-D substation; ISO market sees a single virtual resource at each T-D interface Distribution-level energy prices Locational energy prices based on LMP + distribution component (e.g., LMP+D) Based on value of local DER services, using wholesale LMP only for imports/exports Resource/capacity adequacy As today, based on system coincident peak plus load pocket & flexibility needs; opt-out allowed for micro-grids Layered RA framework: DSO responsible for each T-D interface area; ISO responsible to meet net interchange at each interface Grid reliability paradigm Similar to today Layered responsibilities; e.g., DSO takes load-based share of primary frequency response Multiple-use applications of DER (MUA) DER subject to both ISO and DSO instructions Rules must resolve dispatch priority, multiple payment, telemetry/metering DER subject only to DSO instructions, as DSO manages DER response to ISO dispatches & ancillary services provision Regulatory framework Federal-state jurisdictional roles similar to today Explore framework to enable states to regulate distribution-level markets Comparison to existing model Current distribution utility roles & responsibilities, enhanced for high DER Total DSO is similar to a neighboring balancing authority or TSO

The future grid may be an “integrated decentralized” system, a layered hierarchy of optimizing sub-systems. Storage, DG and controls on premises form a building-level microgrid Each layer only needs to see its interchange with next layer above & below, not details inside other layers ISO optimizes regional bulk system only up to the T-D interfaces Layered control structure reduces complexity, allows scalability, and increases resilience & security Fractal structure mimics nature’s design of complex organisms & ecosystems.
