EPRI.

1976 EPRI Forecast

• It’s a part-time performer – where

24/7 is expected.

• Solar-thermal generating stations –

promising mid- to long-term possibility

• Photovoltaic conversion – is

attractive but behind solar thermal

• Obstacle – capacity displacement,

storage the key

• Outlook – 1-2% of the nation's

electric power capacity by the year

Key Terms to Know

– Hosting Capacity

– DRIVE

– Smart Inverters

– DERMS

– Integrated Grid


What is Hosting Capacity and Why is it So Important?

Definition:

– Hosting Capacity is the amount of DER that can be accommodated without adversely impacting power quality or reliability under current configurations and without requiring infrastructure upgrades.

Hosting Capacity is

– Location dependent

– Feeder-specific

– Time-varying

Hosting capacity considers DER interconnection without allowing

– Voltage/flicker violations

– Protection mis-operation

– Thermal overloads

– Decreased safety/reliability/power quality

Hosting capacity evaluations require precise models of entire distribution system

Hosting Capacity can be used to inform

utility interconnection processes and to

support DG developer understanding of

more favorable locations for interconnection

A feeder’s hosting capacity is not a single value, but a range of values


Distribution Resource Integration and Value Estimation Tool

(DRIVE)

Distribution Resource Integration

and Value Estimation Tool

(DRIVE) is a software tool

developed that determines

distribution system impacts from

DER (hosting capacity)

A single setting won’t

work for all locations

Multiple locations on

change the result

Summary IEEE P1547 Full Revision as of June 28, 2016

Voltage regulation – near completion

Under- and Over-voltage and frequency ride through – near completion

Power Quality (harmonics, flicker, TOV) – near completion?

Communication (monitoring and control) – need additional work

Interoperability – need additional work

Unintentional islanding prevention – need additional work

Microgrid – early stage

Interconnection test requirements – early stage

Simulation and modeling data requirements – early stage


Grid Provides Balancing without Battery –For example the Zero Energy House
