In this paper, an optimization methodology, which uses a heuristic algorithm, is developed in order to maximize the active power generation of wind power plants in distribution networks during maintenance situations. Traditionally, distribution system operators are not taking risks during the maintenance operation by shutting down wind power plants while the reconfiguration is performed. However, the developed methodology presented that the active power outputs of wind power plants' can be curtailed instead of shutdown operation while keeping the distribution network in design and stability limits. Further studies and developments are performed in Danish funded NetVind project to improve the operation of a real distribution network with a high penetration of wind power by exploiting control capabilities of wind power plants.

This paper describes an optimization study of wind power plants' inertial response for different wind speed and penetration levels in power systems. The paper is presenting an optimization method employing a genetic algorithm with an objective function, where the frequency nadir, the seconddip value and the time to reach the frequency steady state are taken into account. As the genetic algorithm is a minimization algorithm, distinct weighting factors of each component enables the adjustment of the optimization according to different specific requirements defined by transmission system operators. The results presented that for the above rated wind speed and medium wind speed operating regions, wind power plants can provide support to the frequency control and improve the performance regarding the frequency nadir and time to reach the steady state. However, the operation region which is closed to the rated wind speed can create a second frequency dip after the nadir. [ABSTRACT FROM AUTHOR]
