  3. Management of Distributed Battery Storage Systems, Caisheng Wang
  4. High Renewable Energy Penetrations within Isolated and Remote Area Power Systems, Michael Negnevitsky. This is a new working group formed in

The Excitation System and Controls Subcommittee is maintaining 6 standards: 421.1-421.6. A PAR is in place and revisions are underway to update IEEE 421.1 Standard Definitions for Excitation Systems for Synchronous Machines for ballot in 2018. IEEE 421.2 Guide for Identification, Testing, and Evaluation of the Dynamic Performance of Excitation Control Systems and IEEE 421.4 Guide for the Preparation of Excitation System

Specifications were revised and published in 2014. IEEE 421.3 Standard for High-Potential Test Requirements for Excitation Systems for Synchronous Machines and IEEE 421.5 Recommended Practice for Excitation System Models for Power System Stability Studies were both revised and published in 2016. Brand new IEEE 421.6 Recommended Practice for the Specification and Design of Field Discharge Equipment for Synchronous Machines was successfully balloted and published 23 March 2017. The subcommittee had a 2 hour panel session on Power System Stabilizer and Excitation Limiter Practical Issues in the Modern Grid. This led to a request to revise the Power System Stabilizer tutorial document and panel. Additionally, members of the Subcommittee presented the impacts of Grid Codes on Excitation Systems standards and design and use of the SC standards 421.2 and 421.5 at the 2017 general meeting.

The Hydroelectric Power Subcommittee (HPS) governor harmonization taskforce completed a draft harmonization of governor terms and definitions between IEEE and IEC governor standards and submitted the proposed harmonization document to the IEC TC14 working group for review and comment. The HPS and TC14 have agreed to form a joint working group to develop a project for creating a dual logo standard containing harmonized speed governor terms and definitions. The subcommittee presented two panel discussions at the 2017 PES General Meeting; one titled “Integrating Wind and Solar with Your Hydro”, and the other titled “IEEE Standards and Guides Developed by the Hydroelectric Power Subcommittee.”

The Renewable Technologies Subcommittee organized a well-attended Panel Session titled “Current R&D in Photovoltaics: Technology and Grid Integration” at the General meeting. There were 7 panelists. This was organized by Dr. B. Chowdhury of UNCC.

The Integration of Renewable Energy into the Transmission and Distribution Grids Subcommittee has two Working Groups:

  • Wind Plant Collector System Design (Chair: Doug Price)
  • Wind and Solar Plant Interconnection Working Group (new name, Chair: Jens C. Boemer). The scope of this WG was revised:
    • Serve as a focal point for technology and solutions providers within the Power and Energy Society (PES) for addressing issues related to interconnection performance requirements, testing, and validation of transmission- and distribution-connected wind and solar
    • Contribute expertise from the manufacturers and developer’s perspective on grid interconnection standards, grid supportive functions and plant control modes to meet modern grid codes.
    • Conduct activities to promote the sharing of knowledge and experience among diverse organizations working on similar issues through the conduct of symposia, workshops, paper sessions, (joint) panel sessions, and
    • Publish working group papers to document results of working group activities and to share working group positions on issues related to wind and solar plant

The Subcommittee completed the wind plant grounding guide, started a solar grounding and dc design guide, and initiated a PAR for personnel safety related to wind and solar plant grounding. The Subcommittee also sponsored two panels and supported three technical sessions at the 2017 General Meeting.

Benefits to Industry and PES Members from the Committee Work

The various subcommittees within the Energy Development and Power Generation Committee inform members and other interested individuals through standards and paper / panel sessions as mentioned above on new developments in their areas of expertise. In coordination with the T&D Distribution Subcommittee and the T&D

Distributed Resources Integration WG, the committee offers a technology perspective about the state of the art of grid integration and interconnection requirements technology solutions.

Benefits to Volunteer Participants from the Committee Work

By actively working on the committee, members are able to contribute their knowledge to the industry while at the same time earning Professional Development Hours that count toward their various PE continuing education requirements.

Volunteers get opportunities to propose panel sessions, discuss cutting edge power system operation and planning problems with leaders and experts in specific fields, and invite right individuals to attend panel sessions.

Volunteers also benefit from technical paper reviews and presentations.

The IEEE 421 series of excitation system standards, developed and maintained by the Excitation System and Controls Subcommittee, are used worldwide by all vendors, transmission planners and operators and generator owners to specify, commission, test, tune and model excitation controls and confirm coordination of limiters and protections to meet current and evolving electric grid codes. Work is underway in IEC to harmonize or adopt IEEE standards, in particular 421.5, to recognize the international nature of excitation system design, tuning and testing.

Hydroelectric Power Subcommittee participants are afforded a reason to attend meetings that are held at the PES General Meeting and HydroVision (alternating years). These conferences, and of course, the working group meetings themselves are excellent opportunities for networking and continuing education.

Participants gain an understanding of the technical issues discussed during ongoing working group standard revision efforts. This provides alternative approaches and experiences to address common challenges and supports knowledge transfer of best practices.
