Controllers Reference Frames In grid-tied PV systems, inverter plays a prominent role in energy harvesting and integration of grid-friendly power systems. The reliability, performance, efficiency, and cost-effectiveness of inverters are of main concern in the system design and mainly depend on the applied control strategy.
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.
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.
