Associate wind and solar with natural gas

[yanhuan0713]

Associate wind (and solar) with natural gas/storage: There may be three ways to accomplish this. Select one.

• Define load curves for solar and wind: This is the approach suggested by VEDA developers on their forum. However, the details for implementation of this particular approach are lacking in the TIMES/VEDA documentation. A successful implementation should incorporate the daily and seasonal variation of these electricity sources, and force the model to deploy natural gas or electricity storage to supplement wind and solar.
• Replace annually averaged capacity factors and/or PEAK factors with seasonal (summer/winter) and diurnal (day/night) (i.e. SN,SD, WN, WD [2]) capacity factors : The model may then automatically deploy natural gas to supplement wind and solar. If seasonal versions of these factors exist, this would be the easiest solution. TIMES Documentation Part II [1] may offer some insights in this regard.
• Define a direct relationship between the capacities of wind and natural gas:It might be possible to define a direct equation between the installed capacity of renewables and natural gas. Since no straightforward way to do this is described in the VEDA documentation [2], this would require utilization of the TIMES documentation [1], the VEDA attributes table, and possibly the assistance of the VEDA forum.
