Accommodating High Levels of Variable Generation - NERC

Appendix I: 2009-2011 Objective and Work Plan
1.4. Resource adequacy and transmission planning approaches must consider needed
system flexibility to accommodate the characteristics of variable resources as part of bulk
power system design.
Resource Issues Subcommittee Start Date: 2 nd Qtr. 2009 End Date: 4 th Qtr. 2010
• Study resource and transmission planning process changes required to include
variable generation characteristics such as ramping, fuel mix, minimum generation
levels, shorter scheduling intervals, etc.
• Identify data requirements to support resource adequacy assessment and which NERC
entities should collect, retain and provide this data.
1.5. Integration of large amounts of plug-in hybrid electric vehicles, storage and demand
response programs may provide additional resource flexibility and influence bulk power
system reliability and should be considered in planning studies
IVGTF – Planning Sub-Group Start Date: 2 nd Qtr. 2009 End Date: 3 rd Qtr. 2010
Assess the influence on bulk power system reliability of accommodating large amounts of
charging/discharging battery electric vehicles, storage and demand response along with smart
grid technology, including integration on the distribution system.
1.6. Probabilistic planning techniques and approaches are needed to ensure that system
designs maintain bulk power system reliability.
IVGTF – Planning Sub-Group Start Date: 2 nd Qtr. 2009 End Date: 3 rd Qtr. 2010
Define probabilistic techniques/criteria that can be used with variable generation and produce
a handbook on study methods for system planning.
