As an important part of power conversion in distributed generation, grid-connected inverters can convert the DC power generated and converted by new energy sources such as solar energy and wind energy into AC power. According to their output characteristics, they are divided into grid-forming inverters and grid-following inverters.
Adaptive Control Strategy of Grid-Connected Inverter 3.1. Adaptive Control Strategy of Power Grid Voltage PV inverters need to control the grid-connected current to keep synchronization with the grid voltage during the grid-connection process.
When modeling grid-connected inverters for PV systems, the dynamic behavior of the systems is considered. To best understand the interaction of power in the system, the space state model (SSM) is used to represent these states. This model is mathematically represented in an expression that states the first order of the differential equation.
Interaction between inverters and power grid. For N grid-connected inverters, the Bode diagrams of the coefficient from the inverter output voltage to the common bus voltage and the coefficient from the power grid voltage to the common bus voltage are drawn as shown in Figure 10 a,b, respectively.
This, in turn, equips inverters to meet the burgeoning demands of grid connection and support. As technology advances, capabilities such as wide short-circuit ratio adaptability, harmonic current control within 1%, and continuous rapid low- and high-voltage ride-through will be key for grid connection.
