The objective of this paper is to implement a two-phase, interleaved, bidirectional DC/DC converter topology with an improved voltage conversion ratio for electric vehicle (EV) and DC-microgrid systems. In this study, a two-phase interleaved charge-pump topology is introduced to achieve a high voltage conversion ratio with very simple control circuits. In discharge mode, the circuit topology ac...

variation of frequency and voltage by load changes in a microgrid is a challenge in droop control method. centralized restoration frequency or voltage in a microgrid requires communication link and therefore affects the advantage of decentralized droop control such as reliability, simplicity and inexpensiveness. this paper proposes a decentralized method that restores the frequency of a microgr...

Abstract This paper presents the power flow modelling for AC/DC hybrid islanded microgrids including droop-controlled distributed generation units, secondary frequency and voltage restoration control AC side of microgrid, DC microgrid. The interlink converter between includes a frequency-voltage droop control, considers effect microgrid side. Two case studies are presented model evaluation, in ...

Abstract A distributed autonomous economic control strategy is proposed to realize the operation of DC microgrid in islanded state. The first introduces incremental cost primary control, but due influence line impedance, it not possible precisely achieve consensus at each unit, and generates a steady-state error. To overcome this problem, secondary based on dynamic algorithm designed basis whic...
