Comparing the knowledge bases of wind turbine firms in Asia and Europe: patent trajectories, networks, and globalization. Science and Public Policy, 1-16. doi: 10.1093/scipol/scv055 Comparing the knowledge bases of wind turbine firms in Asia and Europe: patent trajectories, networks, and globalisation Yuan Zhou1, Xin Li2, Rasmus Lema3, Frauke Urban4 1 School of Public Policy and Management, Tsinghua University, Beijing, China 2 School of Economics and Management, Beijing University of Technology, China 3 Department of Business and Management, Aalborg University, Denmark 4 School of Oriental and African Studies SOAS, University of London, UK Abstract This study uses patent analyses to compare the knowledge bases of leading wind turbine firms in Asia and Europe. It concentrates on the following aspects: (a) the trajectories of key technologies, (b) external knowledge networks, and (c) the globalisation of knowledge application. Our analyses suggest that the knowledge bases differ significantly between leading wind turbine firms in Europe and Asia. Europe’s leading firms have broader and deeper knowledge bases than their Asian counterparts. In contrast, Chinese lead firms, with their unidirectional knowledge networks, are highly domestic in orientation with respect to the application of new knowledge. The Indian lead firm Suzlon, however, exhibits a better knowledge position. While our quantitative analyses validate prior qualitative studies it also brings new insights. The study suggests that European firms are still leaders in this industry, and Asian lead firms are unlikely to create new pathways that will disrupt incumbents in the near future.

In this line, dynamic models of wind turbines able to emulate their response against grid disturbances, such as voltage dips, are required. To address this issue, the International Electronic Commission (IEC) 61400-27-1, published in 2015, defined four generic models of wind turbines for transient stability analysis. To achieve a widespread use of these generic wind turbine models, validations with field data are required. This paper performs the validation of three generic IEC 61400-27-1 variable-speed wind turbine model topologies (type 3A, type 3B and type 4A).
