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.
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.
Step changes in the inverter’s reference power show the strategy’s quick adaptation to reactive power demands, while maintaining a stable active power supply. Furthermore, active power control disconnects the BESS when it approaches its lower SoC limit in a near-depleted battery scenario.
In the grid-connected inverter, the associated well-known variations can be classified in the unknown changing loads, distribution network uncertainties, and variations on the demanded reactive and active powers of the connected grid.
Auxiliary functions should be included in Grid-connected PV inverters to help maintain balance if there is a mismatch between power generation and load demand.
Feedback linearization controller block diagram proposed in Ref. . Another nonlinear control method used in the grid connected PV system is the hysteresis current control, which is a simple and useful technique to obtain fast dynamic response inside the current control loop.
