Modern Photovoltaic Installation Connected to the Distribution and Transport Network

The research on photovoltaic (PV) installations linked to the electrical distribution and transport network, as well as these malfunction detection devices, is the subject of this chapter. This project relies on injecting 16 KW of power onto the medium voltage electrical network from a PV panel field (25 KV). We have interposed blocks that control the opening and closing of the power switches of the DC/AC converter and synchronise the phase, amplitude, as well as the frequency of the voltage and current, injected into the electrical network in order to make the injection system reliant on the network and to minimise power losses. The simulation results demonstrate that the planned system detects system failures on the network side (voltage dip, phase shedding, frequency fluctuation, imbalance of the three-phase system), on the field side of the PV panel (distrust of converters, etc.), and ensures that electrical energy is injected into the network while the PV generators are operating.
