When received, this section will also be incorporated in the paper.
Juergen Holbach provided a draft on zero sequence compensation. The draft contained too many equations; Juergen agreed to revise the draft and provide it well before the next meeting of the Working Group.
C9: Underfrequency Load Shedding and Restoration
Chair: A. Apostolov
Vice-Chair: K. Behrendt

The working group met on Tuesday,
May 22nd, with 15 members and 7 guests present. The working group reviewed the
guide’s scope, purpose, and outline that were developed at previous meetings.
Very few new writing assignments have been received. The outline was reviewed
to clarify and confirm commitments for the remaining writing assignments. The
chairman will merge the writing assignments into an IEEE formatted document,
which will be emailed to the working group members.
Changes and new writing assignments
should be emailed to the working group chairman by the end of July. These
changes and contributions will be compiled and redistributed by the middle of
August, so comments can be received before the September meeting.
All writing assignments shall be
submitted in either Word 97 or RTF format with a file name that includes the
document section number, revision number, and authors last name
(<section_number_Rn>_AuthorsLastName>.zip, or .doc, or .rtf). Figures
should be included in the text, and also sent as separate graphic file
attachment. References to Figures included in the text should include the name
of the Figure.
The scheduled completion date of
December, 2001, is questionable at this time.

Report of the IEEE PES Power System Stability Controls SC to the PSRC
Gary Michael
The Subcommittee met January 30, 2001 in Columbus with around 60 members and guests attending. Following the business meeting, the SC sponsored a morning technical paper session with three transactions papers and two proceedings papers. In the afternoon, the SC sponsored the panel session Fast-Acting Load Control for System and Price Stability. The panel session was of high interest, with attendance of 80-plus.
On January 29, the SC co-sponsored the panel session Maximizing Benefits of Generator Temporary Overexcited Capability. Papers from both panel sessions are available to subcommittee and committee members at http://www.transmission.bpa.gov/orgs/opi/index.shtm under IEEE Power System Stability Controls Subcommittee.
The Power System Dynamic Measurements WG chaired by Dick Schulz is preparing the paper "Preferred Capabilities for Power System Dynamics Measurements."
The SC is forming a Task Force on Fast-Acting Load Control for System and Price Stability. Jeff Dagle is chairman. A position paper is planned, along with a second panel session at the 2002 WM. The idea is to take advantage of current need for direct load control/real-time pricing for demand management and consumer price-based load reduction. With appropriate design, the same infrastructure can be used for stability control, especially longer-term voltage stability.
The SC is also forming a new Task Force on Tests Systems for Stability Controls. Ian Hiskens is chairman.
At the Vancouver 2001 SPM, the SC is planning a panel session on Recent Experience with Emergency Stability Controls. Panelists are from Hydro Quebec, Bonneville Power Administration, CEPEL-Brazil, Power System Emergency Control Laboratory-Russia, and Iowa State University. The session will include implementations following major disturbances, and use of PLC and other digital controls. Members are participating in two new CIGRE task forces: TF 38.02.23, Coordinated Voltage Control in Transmission Networks, and TF 38.02.24, Defense Plans Against Extreme Contingencies. Possible new work includes emergency voltage stability controls, stability controls in the new industry environment, PSS tuning guide with emphasis on new equipment and inter-area oscillations, and stability controls for power electronic devices.
Phil Winston: Nothing
major to report.
