Commonly used communication technologies for inverters As the brain of the entire power station, the photovoltaic inverter can transmit the collected power station operation data to the communication hardware.
Between the CCM and VCM mode of VSI, the CCM is preferred selection for the grid-connected PV systems. In addition, various inverter topologies i.e. power de-coupling, single stage inverter, multiple stage inverter, transformer and transformerless inverters, multilevel inverters, and soft switching inverters are investigated.
The characteristics of different communication methods of inverters are obvious, and the application scenarios are different. In order to better weave the underlying network of energy digitization and intelligent development, choose the most appropriate communication method according to local conditions.
We propose a passivity-based control strategy to enhance the stability and dynamic performance of grid-forming multi-inverter power stations and address these challenges. The inner loop designed from the perspective of energy reshaping, ensures the stability of the inverter’s output.
Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
Generally, each inverter is equipped with a GPRS/4G data collection module. Through the built-in SIM card, the collected data is uploaded to the inverter company's server through the wireless network and the communication base station. This method is easy to use and does not require additional wiring, but traffic charges is needed.
