Abstract
The global trend towards renewable energy sources (RES) involves power systems facing strong increase in power electronic-interfaced generation units like wind and solar. One goal of the EU-funded MIGRATE project [4] was to identify stability issues accompanying this trend as well as to develop and test suitable mitigation measures. As one result, the use of grid forming (GF) control schemes is suggested as an alternative to the currently applied grid feeding control schemes. This paper continues the short-term voltage stability studies performed within MIGRATE, focusing on the GF share necessary for full stabilization in a detailed future grid model. In addition, system stability trends when approaching this specific share are assessed. Under consideration of power electronic (PE) levels from 72% to 90%, the necessary GF share was found to range from 17% (at 72% PE) to 50% (at 90% PE). When increasing the GF share up to a value ensuring sufficient system stability, the major stability improvement was seen in the last quarter of this increase. Therefore, being aware of the necessary GF share is especially significant for practical grid operation. Further on, while keeping an eye on the reactive power capability of the system, a case with a PE penetration of 93% was fully stabilized by roughly staying with 50% of GF controls.
