This paper develops a global model of a two-stage grid-connected microinverter which uses sliding-mode control laws in both stages. In the study, it is considered that the microinverter is fed by a current source representing the photovoltaic module with a capacitor connected in parallel. The model of the DC-DC stage is obtained from the linearization of the ideal sliding dynamics of the converter...
The paper presents a set of probabilistic functions based on stochastic RES (PV and Wind) forecasting and probabilistic load flow, which use the AMR (Automatic Meter Reading) infrastructure for data acquisition at MY Networks and the SCADA measurements at the MA" bus. More specifically, probabilistic functions are implemented, in order to provide improved monitoring of the system state, identification...
This paper presents simulation results from a real case study of a medium scale photovoltaic (PV) system integrated into an 11kV distribution network. The investigated system is a semi-rural part of an existing distribution network in Queensland, Australia with planned investments of more than 3MWp PV installation. The studied case is very interesting because of planned high penetration of PV power...
A growing number of North American utilities are experiencing a significant proliferation of photovoltaic distributed generation (PV-DG). PV-DG integration can pose a challenge to distribution utilities due to the variety of impacts on several aspects of distribution systems planning and operations and the fact that hitherto distribution feeders have been designed and operated for supplying unidirectional...
This paper presents a hybrid control strategy for photovoltaic (PV) simulator, which emulates the output characteristics of PV arrays under different irradiation, temperature, and loads. The mathematic modeling of the I-V curve of PV arrays is investigated in this paper, and accordingly the voltage control or current control method is worked out for different segments of PV output characteristics...
