Power losses minimization within Spanish wind farms evacuation networks

Abstract

The aim of this paper is to evaluate the influence on power losses of the provision of voltage control by wind farms within the grid that connects them to the transmission network. In addition, the paper estimates the economic profit or cost that this technology could obtain in case of providing voltage control. This paper concentrates on the Spanish situation, where wind farms are connected to the transmission network by an evacuation network without containing loads. Thus, from the economic point of view, just the wind farms owners are affected. The results presented in this paper have been obtained for a real representative Spanish wind evacuation network.

Developing Realistic Designs for Wind Farms: Incorporation of an Imperialist Competitive Algorithm

“…Moreover, they demonstrated that DFIG is able to minimize the loss for various reactive power designs. Saiz-Marin et al [19] assessed the impact of power loss due to expanding voltage control in a grid connecting wind farms to the transmission network, and the benefits and costs which extend from developing voltage control. Lumbreras and Ramos [20] utilized mixed integer programming and decomposition strategies for optimally designing offshore wind farm layouts (OWLs) considering such constraints as transformer and redundant cables requirements.…”
