“…By comparing these results with those of (Benelkadi et al 2018) in Algeria, (Salisu et al 2019) in Nigeria, (Aboagye et al 2020) in Ghana, (Sanwogou et al 2019) in Togo, (Imam et al 2019) in Saudi Arabia, (Dagtekin et al 2014) in Turkey, (Vakili et al 2022) in Italie, (Poudyal et al 2021) in Nepal, we deduce that the price per kWh of electricity obtained for scenario 6 is higher. However, the price displayed in the work of (Hanen et al 2018) in Tunisia, (Singh and Rizwan 2023) in India, (Hassanea et al 2022) in Tchad is respectively much higher (0.81 USD/kWh, 0.61USD/kWh, 0.33 USD/kWh) than ours as well as the return on investment period obtained by (Aboagye et al 2020) in Ghana (15 years), (Sanwogou et al 2019) in Togo (8.6 years), (Dagtekin et al 2014) in Turkey (7.8 years), (Imam et al 2019) in Saudi Arabia (14.6 years), (Vakili et al 2022) in Italie (6.2 years), (Poudyal et al 2021) in Nepal (8.6 years). The studies of Amoussou in Benin and more precisely in the city of Kandi confirms the results of this study on the price of kWh which varies from 0.09 USD to 0.23 USD for a system without storage and with energy storage according to the 'author.…”

“…This economic analysis shows that the photovoltaic solar system project on the USTO campus can be considered a profitable investment with a substantial financial contribution. Hanen et al (2018) carried out a design and technical-economic evaluation of a grid-connected PV system in the city of Tozeur (Tunisia), with a size of 10 MW. The numerical simulation was carried out using Homer software and an Excel application.…”

In developing countries, institutions that have to operate continuously during daylight hours consume relatively large amounts of electrical energy for lighting and air conditioning, leading to high bills. Untimely power cuts lead to a fluctuation in the voltage delivered by the conventional network, which induces the malfunctioning of electrical equipment and the discontinuity of judicial work. The use of photovoltaic solar energy makes it possible, on the one hand, to ensure continuity of service in the event of damage, and on the other hand to stem greenhouse gas emissions through the sustainable nature of this energy. Solar installations also make it possible to maintain the permanent power supply in the event of instability of the electrical network and to correct the voltage variations undergone by the energy equipment. Thus, this (case) study is based on the energy balances evaluated on the buildings of the jurisdiction of the city of Kandi (Benin) to propose effective solutions of electrification according to six (6) technical scenarii. Each component of the back up system has been sized considering technical requirements and an economic and environmental study has been carried out. The results indicate that the integrated scenario 6 of a "back-up" system with a solar fraction of up to 37% (49.5 kWc) seems to be the most suitable conf iguration for the current needs of the Kandi jurisdiction due to the shortest time to return on investment (5.1 years) and the maximum annual savings generated (33,674 USD). The environmental impact study has made it possible to determine the CO2 emissions avoided as well as the contribution of Carbon credits that this jurisdiction would reap has been evaluated at 115.8 tCO2 equivalent, or 10.6 hectares of forest carbon preserved over the life of the project. This configuration is therefore strongly recommended for a sustainable energy mix in the jurisdictions of Benin as well as for administrative or similar sites where electricity consumption is maximum during the day.

“…where ed, eq are the direct and the quadrature grid voltages, respectively, Id, Iq are the direct and the quadrature grid currents, respectively, ω=2πf the pulsation and f is the fundamental frequency of grid voltage f=50Hz and s is the Laplace operator. To cure the problem of the coupling which exists between the directaxis and quadrature-axis currents, the decoupling method described in [17] is proceeded.…”

“…Two regulators (Id regulator and the Iq regulator) are added to the control structure to minimize the error between the setpoint and the measured value. In the aim of separately controlling the direct and quadrature currents, the coupling terms ( n and n ) are eliminated by the compensation method described in [17]. The synchronization between the generated signals and that of grid has been accomplished by the phase locked loop (PLL) block, based on a multi-variable filter (MFV) [17].…”

The fuzzy logic strategies reported in the literature about the control of direct drive permanent magnet synchronous generator (PMSG) connected to grid are limited in terms of inclusiveness and efficiency. So an overall control based on fuzzy logic and anti-windup compensation is proposed in this paper. Aiming at the inadequate of hill climb search (HCS) MPPT with fixed step size, the fuzzy logic is introduced in the stage of "generating rotor speed reference" to overcome the oscillations and slowness in traditional method. PI controllers are replaced by anti-windup fuzzy logic controllers in the "machine side control" stage and in "grid side control" stage to pertinently regulate the reference parameters. Then comparison tests with classical methods are implemented under varying climatic conditions. The results obtained demonstrate that the developed control is superior to other methods in response time (less than 4.528E-04 s), precision (an overshoot about 0.41%) and quality of produced energy (efficiency is 91%). The study verifying the feasibility and effectiveness of this algorithm in PMSG wind turbine connected to grid.
