A Fair Allocation Method of Curtailed Power for Wind Farms Considering Transmission Line Capacity and Conditions for Fair Allocation

In a system with a large number of renewable energy sources such as wind farms (WFs), the WF's output would be curtailed in order to maintain the supply-demand balance when it is predicted that there would be excess power generation in the entire system. In this case, it is important to maintain the transmission line flow within its capacity, to ensure fairness among WFs, and to minimize the curtailed power. In this paper, we propose a fair allocation method of curtailment opportunities considering transmission line capacity and identify the conditions for fair allocation. The validity of the method and the conditions have been confirmed by numerical calculations.
