Contact UsThe increasing number of megawatt-scale photovoltaic (PV) power plants and other large inverter-based power stations that are being added to the power system are leading to changes in the way the power grid is operated.
The efficiency of the inverter drives the efficiency of a solar panel system because inverters convert Direct Current (DC) (as produced by the solar panels), into Alternating Current (AC) (as used by the electric grid). This leads many to wonder what effect over-sizing or under-sizing an inverter will have on overall system efficiency.
For instance, PV inverters may help maintain stability after a system disturbance, such as a short circuit caused by a lightning strike on a transmission line, which may trigger a FD signal that is responsible for opening the faulted line's circuit breakers .
The major advantages of an on-grid solar inverter are that there is no limitation of the load and we can export extra electricity to the grid. You can also avail up to a 70% subsidy on these inverters. However, these do not work in case of a power cut and has no battery backup. Solar Inverters have come a long way.
The photovoltaic is connected to a DC-DC converter which is connected to the DC terminals on the inverter. The DC link capacitor is consisted of a small value film capacitor. The properties of the inverter are listed in Table 1. The phase lock loop (PLL block) in is used to generate the three reference currents for the system control. Fig.1.
In this work, a control scheme for PV inverters is proposed toact during faults that could compromise the transient and voltagestability of a hybrid power system.
