Abstract
Site selection of onshore wind farms involves various evaluations. Evaluation of business feasibility includes calculating annual energy production based on wind conditions. Recent contracts for new connections to the power grid have been on a non-firm basis, which requires power plants to curtail their power when grid congestion occurs. Site selection in the future should consider power curtailment caused by grid congestion. Multi-area Regulation program (MR) is a simulator that can consider the supply-demand balance and the balancing capacity. The latest update of MR enabled the calculation considering grid congestion. This paper calculated the power curtailment of onshore wind farms in Hokkaido in FY2030 with MR. The power curtailment of onshore wind farms varied from node to node, and the curtailment rate around the Nishi-Nayoro substation was 34-38%, higher than any other node. The evaluation with supply-demand analysis is informative for the site selection of onshore wind farms.
