PAP 16 History

We started in January, 2010 with a meeting, a brochure,
and the beginning of a plan.
There were some papers, some White Papers, and some
help from NIST and others.
We held an organizing meeting in March and started
having bi-weekly meetings.
The SGIP was growing at the same time, so we were asked
to develop new things and to try new documentation and
so forth
We developed a list of ISO’s and others that required data
from Wind Plants and compiled THE LIST!

In June, 2010, we started to address the list and said we’d
like to have a guidebook.
We held interviews with ISO leaders
We began to learn more about 61400-25

In July 2010, we addressed the Wind Power Coordinating
Committee to tell them what we were doing
After the meeting in St. Louis in October 2010, we wrote
to IEC TC88, the home of 61400-25
Our quad chart had a RED Flag on it because we were not
making progress with the IEC
We knew little about the IEC process
There was no Maintenance team for 61400-25!
By January 2011, we were stalled out
We started to work on adding a member to the US team

In April 2011, our member Anders Johnsson was
appointed to lead the maintenance team.
We nominated Stan Klein to the US TAG Team
We addressed the TC 88 committee to explain what we
were hoping to do. We agreed to address 61400-25-2, the
modeling portion of the standard..\sg3_roadmap.pdf
In July 2011, we developed the formal request to IEC
In October 2011, we heard from the IEC that the task of
including our recommendations was accepted, but that
the descriptions needed work.

By January 2012, An change was made in the IEC
maintenance team
A joint maintenance team was formed, including both TC
88 and TC 57 to address both 61400-25 and 61850, the
substation communications standard.
By February, a disagreement between the 61400-25 and
the 61850 groups was brewing and meetings were held to
smooth out the differences.
PAP 16 decided to hold the application guide until the
standard was complete.
The Joint Maintenance team continues to work.

Background
10

PAP-16 goal is to make 61400-25 suitable for
supporting US practices
-




IEC 61400-25 is wind power extension of IEC 61850
Surveyed ISO/RTO's for requirements
Developed proposed changes to data models in 6140025-2 and provided to IEC
Maintenance Team 25 was formed within IEC TC 88
MT-25 became JWG-25 between TC 88 and TC 57

Wind Plant Weather Data Use Cases
16
Application of Weather Data by Wind/Solar/CHP Generator
 Forecasting data may be used autonomously by a single
turbine or wind farm in the middle of nowhere.

Wind farm determine its own maintenance schedule, taking
next few day low-wind periods into account.
(cleverfarm.com)
Historical data for Wind/Solar/CHP plant siting.
Communication of Weather Data collected by Wind plant
individual turbine and met. tower for other applications:
 Storage charge management and microgrid islanding.
 Markets, operations, outage/restoration, disturbance

Weather Data Types for Wind Forecasts
17
Types of forecasts required for Wind Power:
 Basic operation: Point forecasts
 Operation which takes into account asymmetrical
penalties on deviations from the bid: Quantile forecasts
 Stochastic optimization taking into account start/stop
costs, heat storage, and/or ’implicit’ storage by allowing
the hydro power production to be changed with wind
power production: Scenarios respecting correctly
calibrated quantiles and auto correlation.

Possible Gaps in Weather Standards
18



WXXM is very sketchy with regard to representing
uncertainty, as it is made to transport observations, not
forecasts.
Might be helpful to add info from individual turbines such
as wind speed/direction at turbine altitudes (to better
represent microclimate).
Need better way to aggregate data over various time and
spatial scales. Time and spatial scales vary widely:


Time scales vary between historical data for siting, market
or restoration, rapid data exchange for disturbance analysis
Spatial scales vary between wind/solar generator or farm,
building/campus, microgrid or distribution system, ISO/RTO

Concern with Wind Plant Use Cases
20

It's important to note that there is a big difference
between including wind power forecast data in the
standards (such as 61400-25) and the discussion around
general weather data. It is unclear if general weather
observations, other than those that are part of normal
wind power plants, should be within the scope of Wind
Plant Weather UCs.

Normal wind plant weather data includes: nacelle
instruments and the plant's permanent met tower
instruments that are connected to the wind plant SCADA
system
