Design, Installation and Experimentation of a Photovoltaic Station Connected to the Electricity Grid on the Campus of the University of Oujda (Morocco) | Chapter 2 | Current Overview on Science and Technology Research Vol. 5

 This chapter's goal is to analyse and size a photovoltaic (PV) project connected to the electrical grid in order to lower the campus university's electricity costs in the technopole of Oujda (Morocco). We demonstrate the size calculation (using the PVsyst software) and functionality of a 10 kW solar station connected to the electrical grid to power the three-phase loads.

According to experimental findings from field tests, the 10 kWp installation linked to the network (50 Hz, 230 V, 16 A) primarily provides the three-phase loads before injecting any excess energy into the electrical grid.

The average voltages recorded on the phases (T, S, and R) are in the range of 238V, the currents measured on the phases (T, R, and S) range from 7 to 14 A, and the output voltages linked to the phases (SR, ST, and TR) are in the neighbourhood of 418V. All of the measurements made match the two installations' specs and simulations on the PVsyst programme in very good detail. The campus of the university in Oujda is totally run by sustainable photovoltaic electricity. Currently, we monitor the generation, use, and injection of electrical energy as well as the price of the electricity bill.

Modern Photovoltaic Installation Connected to the Distribution and Transport Network| Chapter 1 | Current Overview on Science and Technology Research Vol. 5

 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.
