Abstract
U ovom radu je dan kratak pregled postupaka upravljanja višestrukim pretvaračima na zajedničkoj DC sabirnici s ciljem istodobne regulacije napona i kompenzacije opterećenja. Naglasak je stavljen na prednosti primjene hibridnog sustava za pohranu energije zasnovanog na baterijama i ultrakondenzatorima za pričuvno napajanje istosmjerne mikromreže. Potom je projektiran sustav regulacije izlaznog napona DC međukruga pretvarača uz podešenje regulacijskih krugova struje baterije i ultrakondenzatora primjenom kriterija optimuma dvostrukog odnosa. Nadređeni sustav upravljanja uključuje proporcionalno kondicioniranje reference napona (eng. droop control) radi jednostavnog omogućenja neovisnog rada više pretvarača na istoj sabirnici, te nadređeni regulator napona koji korigira stacionarnu pogrešku inherentnu konceptu „droop“ upravljanja. Sustav regulacije napona također uključuje unaprijednu kompenzaciju tereta temeljenu na kraćenju dinamike regulacijskog kruga struje. Dobiveni sustavi regulacije napona zasnovani na konceptu „droop“ upravljanja ispitani su simulacijama na računalu u režimima pojedinačnog i zajedničkog rada dvaju pretvarača, i uspoređeni sa rezultatima simulacije dobivenim primjenom koncepta centraliziranog koordiniranog upravljanja pretvaračima.
Abstract (english)
In this paper, a brief overview of control approaches to multiple power converters connected to a common DC bus aimed at simultaneous voltage control and load compensation will be given. The emphasis is put on advantages of applying hybrid energy storage system based on batteries and ultracapacitors for DC microgrid auxiliary power supply. Subsequently, a power converter DC link output voltage control system has been designed along with inner current control loops of batteries and ultracapacitors that are set by the damping optimum criterion application. The superimposed control system level includes proportional voltage reference conditioning realized in the form of so-called droop control, in order to enable straightforward implementation of multiple power converters operating at the same bus, as well as the uppermost-level voltage controller which corrects the steady-state control error inherent to the droop control concept. The voltage control system also includes a feed-forward load compensator based on zero-pole cancelling approach. The voltage control systems thus obtained, based on droop control, have been verified through computer simulations for individual power converter and joint operation of the two power converters at the common DC bus, as well as compared to simulation results obtained by applying the concept of centralized coordinated power converter control.
