Economic assessment on the use of energy storage to improve clustered wind generation transmission

With increasing wind power generation, the extent of concerns becomes greater of wind curtailed loss due to insufficient transmission capacity. This paper reports an optimization method for increasing clustered wind generation transmission using energy storage. In order to maximise the overall benefits, a number of factors have been considered including transmission benefits, transmission costs, energy storage costs, as well as curtailed wind congestion. An example is taken from an actual wind farm to show that the proposed method could achieve optimal transmission benefits. An analysis has also been performed on effect of energy storage costs on the system configuration.
