In a wind farm, the wakes formed by upstream wind turbines decrease the power outputs of downstream wind turbines by reducing wind speed. This wake interference significantly lowers the power production of a wind farm, especially that of a large-scale wind farm. In this paper, we express wind farm power as a differentiable function of location variables. We then apply a sequential convex progra...

Consequently, for many farm households, economic decisions (including technology adoption and other production decisions) are likely to be shaped by the allocation of managerial time among such activities. While time allocation decisions are usually not measured directly, we observe ...
