Apr 22, 2018 · Electricity demand is increasing day by day. To satisfy this increasing demand, it is essential to expand power generation. One easy solution is to integrate distributed generation
The output power of the inverter can be adjusted in real time according to the user''s needs and settings, thereby controlling the power of the entire photovoltaic grid-connected system that is
Review of control of a typical grid-connected inverter Grid-connected inverters control the magnitude and angle of their output current to regulate for example their DC-link voltage (active rectifier) or to regulate real and/or reactive power flows (PQ source). Several approaches towards achieving control of real and reactive power exist.
A “grid-tied” inverter system is one where the inverter is linked to the main electricity feed into the premises, and is thus dependent on the main electricity grid in order to function. The advantage of this type of system is that you save money by using solar power to generate the bulk of your electricity, which then lowers electricity costs.
As indicated by the name grid-interactive, these inverters can export energy into the grid, and require a grid connection (or an equivalent 230 volt AC supply) to operate; if the grid goes down (i.e. a blackout) then they stop operating.
Anti-reverse current working principle: Install an anti-reverse current meter or current sensor at the grid connection point. When it detects that there is current flowing to the grid, a signal is sent to the inverter through 485 communication, and the inverter reduces the output power until the reverse output current is zero.
When it detects that there is current flowing to the grid, a signal is sent to the inverter through 485 communication, and the inverter reduces the output power until the reverse output current is zero. Thereby, the anti-reverse flow function is realized.
Therefore, the solar system related equipment is generally designed with anti-reverse connection circuits to ensure that the solar equipment is protected from damage when the input power is reversed. The simplest anti-reverse circuit is to connect a diode in series with the input circuit, as shown in Figure 1.
