Some cable suspension systems and their effects on the flexural frequencies of slender aerospace structures [PDF]
The effects of several cable suspension configurations on the first free-free flexural frequency of uniform beams have been determined by experiment and analysis. The results of this study confirm that in general the larger the test vehicle the larger is

An AC and DC Inertia Enhancement Strategy for Bidirectional Grid-Connected Converter in DC Microgrid
EnergiesThe virtual synchronous generator (VSG) strategy has good application prospects as an effective measure to improve the grid inertia level. However, VSG strategy cannot stabilize DC voltage and may even affect the stability of DC voltage.
