1 WECC VGS Planning Guide Work Status Yuri V. Makarov WECC VGS Meeting Salt Lake City, UT March 8, 2012

2 2 Overview of the Current Status The 1st version of the Guide has been completed It is still marked as a limited distribution draft due to the reasons explained below PNNL is currently obtaining permissions for reused materials (IEEE, EPRI, …) Only light editing has been done by a PNNLs editor Several reviews were done by PNNLs engineers The Guide has been already distributed for a VGS review Comments, advises, contributions, critiques are welcome! Changes, additions, deletions are possible Deep editing is planned after that A formal internal review process will be applied at PNNL, including peer reviews from very senior staff.

7 7 Rationale (1) Planning process is experiencing new challenges and facing changes because of the increasing penetration of renewable VG. The renewables integration is overlapped with: random effects of deregulation and markets, new forms of cooperation and coordination between balancing authorities, uncertainties with future generation additions, and new elements added to the grid (like energy storage, microgrids, demand-side controls, and others). Generation is becoming more uncertain and less predictable because of: uncertainties with future generation additions, variability of renewable generation, increasingly distributed nature, and random market forces. Transmission impacts such as congestion, system stability and reliability are becoming more random and less related to the economic dispatch patterns used before.

8 8 Rationale (2) System behavior is getting more complicated, more interrelated, more stressed and much less predictable. Topics addressed by planning, such as reliability, stability, performance, economics, and modeling, are changing and require new solutions. New topics, which were not historically considered by planning, arise. Utilities and transmission system operators in the U.S. and abroad have collected a significant experience with handling large quantities of renewable generation. But despite a significant information exchange and multiple sources of information, little effort has been made to consolidate all or most of the related planning challenges (as they are seen by practicing engineers and researchers) in one document. This also concerns a variety of approaches to address them, including new planning practices and new technologies increasingly penetrating the system or currently staying on an experimental level.

9 9 What is the Guides Objective and What is Not This planning guide is reflecting an effort to: Put together multiple sources of information Provide a clear, systemic, comprehensive outline of the problems, both existing and anticipated; their impacts on the system Reflect currently used and proposed solutions by the industry and research community Planning practices Depict new technologies, equipment, and standards; and expected future trends. The guide is not a how to manual. It only provides brief descriptions to a variety of existing planning problems and approaches. The guide limits its content to VGS Charter, and is written with a firm intention to coordinate with WECC planning guides and standards. The guidebook DOES NOT duplicate existing planning standards or contradict existing planning standards and business practices. It DOES NOT cover operating or market functions; however, it is written with an understanding that system planning should be done in connection with system operating and market functions.

10 10 Guides Structure The guide consists of the executive summary, glossary, 11 main chapters, appendices, and the list of references exceeding 500 sources. Current concerns: Is the content too much theoretical sometimes? Is the level of details excessive sometimes? Does he Guide include all important topics? How quickly the content will be getting old? How to reflect differences in opinions?
