The Northern Tier Transmission Group and ColumbiaGrid formed the Wind Integration Study Team (WIST) to facilitate the integration of Renewable Generation into the northwest transmission grid. The initial focus of the group is to support the technical study needs of existing subregional and regional initiatives by addressing the following two issues:
1) Technical evaluation of system constraints on the increased use of dynamic scheduling
– One of the primary products of the WestConnect/NTTG/ColumbiaGrid Joint Initiative (http://www.columbiagrid.org/ji-nttg-wc-overview.cfm
) is the increased utilization of dynamic scheduling. BPA is determining the technical constraints on the various scheduling paths that limit the acceptable magnitude or rate of these schedule changes for WIST review.
2) Action Items from the Northwest Wind Integration Action Plan – The WIST is addressing the following two action items from the Northwest Wind Integration Action Plan: 1) “The Northwest Transmission Assessment Committee (NTAC) should propose a formal technical transmission planning methodology that seeks a balance between the cost of transmission capacity and the value of delivered wind energy”; and, 2) “ColumbiaGrid and the Northern Tier Transmission Group, together with NTAC, should begin applying the NTAC transmission planning methodology to regional transmission planning.”
