Accommodating High Levels of Variable Generation - NERC

Appendix I: 2009-2011 Objective and Work Plan
2009-11 Work Plan Summary
Following are the proposed 2009-11 improvements and work plan recommended by the IVGTF to
NERC’s Planning and Operating Committees (PC/OC) including the suggested lead organization for
each assignment. The PC/OC will make the ultimate decision on the appropriate groups and
assignments respecting these recommendations.
1. Power system planners must account for the impacts of variable generation on power
system planning and design and develop the necessary practices and methods to maintain
long-term bulk power system reliability (NERC’s Planning Committee)
The primary goal of this effort is to provide more consistency in reporting regional resource
reliability assessment results, including but not limited to methods to calculate energy and
capacity, probabilistic analysis, coordinated generation/transmission planning approaches,
study of distributed resources, impacts of integrating large amounts of storage and demand
response, and wind plant modeling requirements.
1.1. Standard, valid, generic, non-confidential, and public power flow and stability models
(variable generation) are needed and must be developed, enabling planners to maintain
bulk power system reliability
IVGTF – Planning sub-group Start Date: 2 nd Qtr. 2009 End Date: 4 th Qtr. 2010
Review the Modeling, Data and Analysis Standards 96 (MOD) for improvements required to
support simulation of power system with high amounts of variable generation.
