The virtual synchronous generator (VSG) is a promising way to deal with the lack of physical inertia and damping introduced by power-electronic-based power supply system. However, characteristics may be complicated in paralleled VSG system due stiff grid interactions between control inverters. In this paper, dynamics parallel inverters VSGs studied. equivalent are derived analyzed detail consid...

Modern utility-scale wind turbines are typically controlled using yaw, generator torque, and blade pitch actuation (Pao and Johnson, 2011). The yaw motor is used to align the rotor with the wind direction for the purpose of maximizing power capture. Generator torque is controlled during below-rated (region 2) operation to maximize power capture by maintaining the optimal tip speed ratio. In abo...

In their paper, G.Gong and S.Q.Jiang construct a new pseudorandom sequence generator by using two ternary linear feedback shift registers (LFSR). The new generator is called an editing generator which a combined model of the clock-controlled generator and the shrinking generator. For a special case (Both the base sequence and the control sequence are mm-sequence of degree n), the period, linear...
