Mar 1, 2020 · An ever-increasing interest on integrating solar power to utility grid exists due to wide use of renewable energy sources and distributed generation. The grid-connected solar
To ensure better system reliability, the interfacing of the microinverter with both the PV module and the grid should fulfill the standards of the PV systems. The main responsibilities of the microinverter are to extract the available maximum power at the PV module and inject sinusoidal current in the grid.
Inverter based MGs are an appropriate, attractive and functional choice for power distribution systems. Inverters in a MG have multiple topologies that have been referenced in various literature. One of the major concerns of MG is their diversity in power generation.
The microinverter or module-integrated converter is a low power rating converter of 150–400 W in which a dedicated grid-tied inverter is used for each PV module of the system.
Inverters in a MG have multiple topologies that have been referenced in various literature. One of the major concerns of MG is their diversity in power generation. Which has a great impact on the two main issues of power distribution performance, namely voltage control and power management.
Discussion Isolated microinverters provide high-quality power by reducing the harmonics in the injected grid current. The galvanic isolation provided by high-frequency transformers also aids in ground fault protection. Therefore, most grid standards for distributed power generation systems are fulfilled by isolated microinverters.
An inverter-based MG consists of micro-sources, distribution lines and loads that are connected to main-grid via static switch. The inverter models include variable frequencies as well as voltage amplitudes. In an inverter-based microgrid, grid-connected inverters are responsible for maintaining a stable operating point [112, 113].
