Investigations on hysteresis-based current control techniques for grid connected photovoltaic systems

Abstract EN

-This paper focuses on delivering an effective performance qualification (PQ) control strategy for a grid connected photovoltaic (PV) system.

A PV-based distributed generation system with a capacity of 10 kilo volt amps (kVA) was connected to the utility side of a power grid operating at 415 V.

The power grid was modelled with a capacity of 100 kVA, 11 kV, and 100 km transmission line length.

The PQ control strategy was implemented with three hysteresis-based current control techniques.

To overcome the drawbacks of conventional hysteresis-control techniques, adaptive tuning of the hysteresis band was carried out, and a vector-based hysteresis current control is proposed to improve the results
