Wind energy generators sitting and sizing based on uncertain generation pricing

0
This paper proposes a methodology for sitting and sizing wind distributed generators (WDGs). These generators are characterised by an uncertain active power production due to the random behaviour of the wind speed. The uncertain generation directly impacts the network total generation cost and also the solution for the placement and sizing problem. So, this work takes into account this uncertain generation and presents a model (bus-based) to deal with uncertainties in active power production. Based on this model, the proposed methodology allows uncertain generation pricing and yields, after successive executions of an optimal power flow, a solution for the sitting and sizing problem of WDGs, considering economic dispatch conditions. Tests were carried out using the IEEE-14 buses system and the obtained results show the impacts of uncertainties in the placement, penetration and energy costs of WDGs.
