Aiming at the problems of transient over-current and over-voltage in switching process AC/DC hybrid microgrid grid-connected mode island mode, which leads to sudden change transmission power seriously affects quality. In this paper, an improved seamless control strategy droop with disturbance observer is designed. The main work as follow: according diffident calculation methods adaptive realized by detecting current frequency Point Common Coupling(PCC) public grid. Secondly, from will cause...
The nonlinear load in AC/DC hybrid microgrid seriously affects the power transmission quality of bidirectional interlinking converter (BIC). In this article, an improved Fryze-Buchholz-Depenbrock (FBD) harmonic current detection method combined with droop control is designed to suppress strategy. decoupled double synchronous reference frame phase locked loop (DDSRF-PLL) self network used eliminate negative sequence fundamental frequency component, and accurate can also be realized when...
