FAQS 4

How to improve the performance of PV system connected to grid?

To enhance the performance PV system connected to grid, the implemented modulation scheme must result in the stable output voltage with lower THD, lower switching loss, higher efficiency of the converter and so on. Hence, it is very critical to choose the modulation scheme for the utilized inverter topology .

How do grid-forming inverters achieve power support and voltage optimization?

This paper proposes a robust voltage control strategy for grid-forming (GFM) inverters in distribution networks to achieve power support and voltage optimization. Specifically, the GFM control approach primarily consists of a power synchronization loop, a voltage feedforward loop, and a current control loop.

How to model grid-connected inverters for PV systems?

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.
