Continuously expanding deployments of distributed power generation systems are transforming conventional centralized grids into mixed electrical networks. The higher penetration and longer distance from the renewable energy source to main grid result in lower strength, which stimulates limitation problem. Aimed at this problem, case studies inductive resistive impedance with different strengths...

For three-level inverters, hysteresis current control (HCC) has been widely used in applications such as active power filters due to its fast-dynamic response, and it does not need each frequency separately with multiple controllers, which makes simpler. However, the large fluctuation range of switching is a serious disadvantage control. Especially, decreases significantly during grid voltage z...

Renewable energy sources such as photovoltaic (PV) and wind energies are integrated into the grid due to their low global emissions higher power conversion efficiency techniques. Grid-connected inverters core components of distributed generation networks. However, several harmonic current voltage variations affect performance circuits in grid-connected These issues can be easily resolved using ...

The last decade has seen a dramatic rise in renewable energy converters connected to the grid, consisting mostly of intermittent distributed generators on the medium or low voltage grid. Due to this evolution in energy transmission, improved monitoring and control of the distribution grid is becoming mandatory in order to efficiently integrate the new power sources and guarantee power quality, ...

This paper deals with the control of pulsewidth modulation inverters connected to the grid through resonant LCL filters. It proposes two alternative (piecewise affine) models that account for the switched behavior of the converter. Based on these improved models, an explicit model-predictive control scheme is derived in order to provide a fast response, making it very suitable for applications,...
