Abstract: To improve grid-connected inverter operation performance, a power oscillation and current harmonic suppression coordinate control strategy that considers the problem of overcurrent is proposed in this work. First, the ...

Abstract: An air-entrained vortex is a complicated and negative phenomenon in a pump sump. Due to the unsteady vortical and two-phase-flow properties, its prediction is challenging. In this paper, advanced turbulence models sensitive ...

Abstract: Renewable energy has the characteristics of fluctuation and intermittence due to environmental conditions; the fluctuation of output power affects the operation of the power grid. To combat these fluctuations, a control ...

Abstract: Separate-layer injection technology is a highly significant approach for enhancing oil recovery in the later stages of oilfield production. Both separate-layer and general injection information are crucial parameters in ...
