Investigating the Power-COE trade-off for wind farm layout optimization considering commercial turbine selection and hub height variation

The results showed that the flexibility of using different turbines and hub heights can provide a useful trade-off between power and cost. The trade-off was found to be wider in offshore cases, which means that the optimization is more useful in such conditions. The optimization for maximum capacity factor acts as a mid-point between the two design extremes of maximizing power and minimizing the cost of energy. Almost all turbines were selected at least once in an optimum layout. However, the priority in selection was for the turbines that have bigger diameter and/or lower rated speed amongst the other turbines of the same rated power.
