Studies on models and algorithms of the power system probabilistic production simulation integrated with wind farm

Abstract

In order to analysis the effect of the integrated wind farm in the power system probabilistic production simulation, a new model of the wind farm output power considering multiwake effect is established according to the probability distribution of the wind speed and the characteristic of the wind generator output power. Compared with the individual wake effect model, this model takes the wind farm as a whole and considers the multi-wakes effect on the same unit. As a result the loss of the velocity inside the wind farm is considered more exactly. Furthermore, a new wind farm model - Time Sequential multi-state Generator Model for the power system probabilistic production simulation involved integrating wind farm is presented. In this model, the fluctuation and sequential characteristics of the wind power are fully taken into account and the wind power is simulated practically. The calculation and analysis have been executed on the IEEE RTS test system integrated wind farms. The results indicate that the models and algorithms presented can be considered the integrated wind farm well and truly in the power system probabilistic production simulation. The above research can also provide a basis for the further study for evaluating benefits of the wind farm. ©2009 IEEE.
