Integration of wind power plants (WPPs) into weak electric grids has gained a lot of interest in recent years due to an increase in sites with low short-circuit power at the point of connection. In response to this reality, wind turbine (WT) manufacturers have been working on developing suitable technical functionalities. However, it can be argued that technology is not the only challenge faced during the interconnection of WPP to a weak grid. This study aims at proposing and demonstrating the application of a process that can be applied to optimise many aspects of such projects and outlines the tools needed to do so. Outcomes and experiences from applying this process and its tools to a real project including steady-state and time-domain simulation results are also presented. It is shown that, in order to successfully interconnect WPPs into weak grids without putting power system safety and reliability at risk, strong collaboration between project developers, network operators, consultants and WT manufacturers is crucial. The proposed process will greatly support all stake holders involved in developing the market of WPPs connected to weak grids.
