The multifunctional operation of photovoltaic (PV) inverters consists in using the PV inverter for ancillary services as reactive power injection and harmonic current compensation. The multifunctional operation can improve the ac-grid power quality. Thus, this paper presents a dynamic method based on the Second Order Generalized Integrator coupled with a(More)
The grid power stability is significantly affected as a result of the net impact of many small photovoltaic (PV) generators, since there is an increase of PV systems connected to distribution systems. There are many ways to improve the system stability, regarding voltage regulation. Some work proposes to use the PV inverter idle capacity to support reactive(More)
Nowadays, non-linear loads are one of the major issues regarding the system power quality. Additionally, the growing presence of distributed generation (DG) systems, which employs converters to connect power sources to the grid may also affect power quality due to its switching. To better utilize such converters, multifunctional operation is usually(More)
