6 FAQs about [Photovoltaic inverter network 380v voltage is unstable]

Do PV inverters have stability problems on weak grid condition?

In the voltage stability problem, the stability problem caused by reactive power compensation is highlighted in particular. The aim of this paper is to give an overall understanding of the stability problems of PV inverters on weak grid condition and present some directions for future research to support the PV stations develop for large scale.

Are inverters connected to a weak power grid?

With the development of PV generation, more and more inverters are connected into the power grid to supply power for users. The grid impedance then becomes large and brings serious challenges to inverter's stability [ 1 - 7 ]. This paper focuses on the stability problems when inverters are connected into weak power grid.

Why is inverter output voltage unstable?

Actually, the large grid impedance probably cause inverter output voltage instability even the control loops are stable [ 59 ]. Given inverters usually work at unit power factor, inverter's output voltage ( Vpv) is in phase with its output current ( Il ).

How many nested control loops does a PV inverter have?

Conventional PV inverters firmware runs at least two nested control loops. One is the AC current control loop to control the inverter output current, purely sinusoidal and in phase with the grid voltage, generating active power.

Is grid connected inverter system unstable?

Based on the impedance model, the authors of [ 2, 3, 7, 25 - 28] have revealed the instability of the grid-connected inverter system by looking into the ratio of inverter output impedance and grid impedance.

Why is inverter stability important in PV power generation?

PV power generation, as one important kind of renewable energy, has been greatly developed. In PV systems, inverters are the crucial parts in energy transmission. Many works have been done about the analysis and improvement of inverters’ stability. The stability problem in and after the designing of inverters are two important topics.
