Intégration des Stations Photoltaïques dans les Systèmes Electriques

Abstract

Renewable energy resources can have a major role in satisfying a large part of the energy needs of mankind. Solar energy does not suffer from a problem of deposit and is available everywhere on our planet for that the production of the electricity base of large-scale PV power plants is promising. But despite all the economic and environmental benefits of photovoltaic production, this generation can lead to a potentially negative impact on the functioning of an electrical system, on the one hand, due to its zero inertia, which makes it easily affected by Climate changes and the intermittency of the primary source. In this work we studied the impact of the injection of the production of the solar power plant of Adrar SKTM on the electrical system of two typical days 12 and 02/13/2017. The injection of the PV power to the grid starts at dawn and takes a maximum value of about 13 hours which corresponds to the peak of the illumination curve. After this time, a declination is observed until the trigger threshold is reached at sunset. And this is the case for the two typical days. Since the active power increases proportionally with the illumination and also decreases with the latter to cancel out at sunset and due to the intermittence of the primary source of renewable sources, it is always necessary to synchronize PV production (renewable source) With conventional sources. It is the production of turbogenerators that ensures demand. Turbogenerators compensate the production disruptions during the day. And take charge of the demand from the triggering threshold of PV production to the synchronization threshold (the dawn). Compensating systems are used both to avoid injecting disturbances into the electrical system and to protect sensitive sources from disturbances on the electrical system. v
