Power System Strength: Evaluation methods, best practice, case studies, and applications

Power systems need to incorporate rising shares of intermittent renewables. The penetration levels of renewable energy sources, inverter-based resources and inverter-based loads have grown, which has negative impacts on the stability and system strength of existing power systems.

System strength describes the ability to manage fluctuations in supply or demand while maintaining the voltage. Metrics for the system strength and the hosting capacity are needed, as well as ways to improve the st...
