As a countermeasure for supply and demand imbalance in case of high penetration of photovoltaic systems, wide‐area supply and demand control is considered. This is performed by adjusting the supply and demand balance by power exchange from areas with surplus reserve capacity to areas with insufficient reserve capacity using cross‐regional interconnection lines. By using our supply and demand control model considering the adjustable range that can respond to a fluctuation after 10 min (10‐min spinning reserve, SR 10 ), we quantitatively evaluate the margin of SR 10 ( SR 10_ margin ) by subtracting the 10‐min residual load fluctuation from SR 10 in the local area. By calculating SR 10_ margin for each time period (month and time of day) and for different targets for reserve capacity (reserve margin and SR 10 ), we investigate the possibility of wide‐area supply and demand control. We find that SR 10_ margin can be secured by changing the reserve capacity within the local area, which demonstrates the feasibility of wide‐area supply and demand control in terms of supply and demand balance. © 2020 Institute of Electrical Engineers of Japan.
