The simulation eventualities incorporate wind velocity and photo voltaic irradiance ramp up and down; a capacitor bank is energized and de-energized; and one-line-to-floor fault happens and clears itself. The simulation results demonstrate the proposed tool is capable of analyzing ability procedure phenomena unfold across time scales. Total article
