Integrated Grid: Distribution Network

• Maintain service quality and reliability

• Impact of DER

• Different distribution network characteristics

• Location matters

Higher Capacity

Lower Capacity

Impact/value assessment must consider unique distribution characteristics

RESOURCE ADEQUACY – Needs probabilistic assessment of DER’s capacity adequacy contribution

Available: Traditional peak demand type adequacy methods (SERVM, GE MARS, E3 RECAP) In Development: Probabilistic expansion planning models which consider both capacity and

flexibility needs (SERVM, E3 REFLEX, EGEAS)

FLEXIBILITY – Needs tools to assess flexibility requirements

& solutions In Development: metrics,

detailed modeling tools (EPRI InFLEXion, E3 REFLEX, SERVM)

GAP: integrated capacity& flexibility expansion planning

OPERATIONAL SIMULATION Needs integration and interaction with DER controls and accurate simulation

of power system operations including impact of uncertainty, reserve provision, variability representation, etc.

Available & improving: production simulation tools (Plexos, SERVM, Polaris System Optimizer, ProMax LT, NREL

FESTIV, ABB GridView, Ventyx PROMOD IV, GE MAPS, UPLAN, Aurora, PowerSym)

GAP: tools /procedures to simulate bulk system and DER interaction

TRANSMISSION PERFORMANCE – Needs bulk system aggregated DER power flow and dynamic models for transmission system performance studies

and probabilistic tools to evaluate transmission system reliability with DER Available: Generic models to approximately capture how DER (wind/solar) reacts

to grid disturbances and load models with some adjustments to account for distribution network. (PSS/E, PSLF, Powerworld, etc)

In Development: transmission reliability tools, tools to consider variability in transmission planning (TransCARE); load models with integrated DER

representation GAP: tools to interact with DER for bulk system voltage & frequency control

DRAFT

DATA – Needs common and

extensive data sets

In Development:

Common data transfer protocols

between bulk system and DER/DSO

New load models and modeling techniques

Forecasting of the location of potential

DER

GAP:

Common data sets for both TSO and DSO

analysis
