- Barriers (and Solutions...) to Very High Wind Penetration in Power SystemsPublication . Estanqueiro, Ana; Jesus, J.M. Ferreira; Ricardo, João; Santos, Amarante dos; Lopes, J. PeçasIn this paper the existing technical barriers that prevent the accomplishment of a very high wind generation penetration in a power system are presented. Since several countries and regions in Europe are already experiencing such high wind penetration or, as a minimum, planning their grids and operation strategies to cope with wind penetration from a high to a very high level, the solutions already identified for the most common constraints are also identified.

- Including a wind energy conversion system model in electromagnetic transients programPublication . Reis, Francisco A.G.S; Estanqueiro, Ana; Castro, Rui; Jesus, J.M. FerreiraDue to the increasing penetration of wind energy, it is necessary to posses design tools that are able to simulate the impact of these installation in distribution grids. Electromagnetic transients programs are suited to deal with these problems, but a detailed wind energy converter model which is able to carry the transient behaviour of this system is also required. In this paper, an interface between two available software package, EMTP and INDUSAT, containing the digital implementation of these features, is presented. This tool will enable the assessment of the influence that both voltage flickering and power oscillations may have in the performance of distribution networks in face of dispersed wind production. A simple case-study is discussed and the main conclusions are commented.
