This article examines the impacts of a transient analysis of a compensator of static synchronous on a system of distribution power (DSTATCOM) on power quality when a PV system DC input source is utilised to supply the system. Due to the nature of these sources' operation, including renewable energy on the input power supply has a variety of ramifications for DSTATCOM's operation. In order to understand the variance in temporal response and its impact on the compensatory process, the dynamic response of the distribution system is investigated under the influence of both battery and PV system sources (PV-Battery). Renewable energy is connected across the dc-link capacitor channel to characterize their impact on the power system's dynamic performance. In this study, three scenarios were investigated: first, photovoltaic (PV) cells are connected solely via the dc-link, second, battery storage is connected solely, and third, a PV system structure (PV cells + battery storage) is explored. DSTATCOM is used to compensate for the reduction in reactive and active power that happens during balanced and unbalanced operation of non-linear loads. The presence of a renewable source enhances the system's power quality by reducing the current source's harmonic components. The Star / Delta transformer is also used to split the three-phase legs of the DSTATCOM VSC, providing a channel for the fundamental zero sequence and a balanced three-phase current. STATCOM control circuit based on synchronous reference frames (SRF).

W niniejszym artykule zbadano wpływ analizy stanu nieustalonego kompensatora synchronicznej statycznej na system zasilania dystrybucyjnego (DSTATCOM) na jakość energii, gdy źródło wejściowe DC systemu fotowoltaicznego jest wykorzystywane do zasilania systemu. Ze względu na charakter pracy tych źródeł, uwzględnianie energii odnawialnej na zasilaniu wejściowym ma różne konsekwencje dla pracy DSTATCOM. Aby zrozumieć wariancję odpowiedzi czasowej i jej wpływ na proces kompensacyjny, badana jest dynamiczna odpowiedź systemu dystrybucyjnego pod wpływem zarówno źródeł baterii, jak i systemu PV (PV-Battery). Energia odnawialna jest podłączona przez kanał kondensatora dc-link, aby scharakteryzować ich wpływ na dynamikę systemu zasilania. W niniejszym badaniu zbadano trzy scenariusze: po pierwsze, ogniwa fotowoltaiczne (PV) są połączone wyłącznie za pośrednictwem łącza prądu stałego, po drugie magazynowanie baterii jest podłączone wyłącznie, a po trzecie, zbadano strukturę systemu PV (ogniwa fotowoltaiczne + magazynowanie baterii). DSTATCOM służy do kompensacji redukcji mocy biernej i czynnej, która ma miejsce podczas pracy zrównoważonej i niezrównoważonej obciążeń nieliniowych. Obecność źródła odnawialnego poprawia jakość zasilania systemu poprzez redukcję składowych harmonicznych źródła prądu. Transformator gwiazda/trójkąt jest również używany do rozdzielenia trójfazowych odgałęzień DSTATCOM VSC, zapewniając kanał dla podstawowej sekwencji zerowej i zrównoważonego prądu trójfazowego. Obwód sterowania STATCOM oparty na synchronicznych ramkach odniesienia (SRF).
