This paper describes a technique to produce electrical energy by a DC motor-generator set. For the realization of our project, we first optimized the photovoltaic energy by using the MPPT control by fuzzy logic, on a DC/DC converter of Boost type. This photovoltaic energy has an electrical power of 14 kW and will feed the DC motor. The DC motor will drive an alternator up to its nominal speed and will produce an electrical power of 14 kW. The simulation results obtained and presented show the feasibility and efficiency of the proposed technology.
The aim of this work is to demonstrate that interphase power regulators (IPR) bring new and interesting ultra-solutions that complement those already taken into account by the FACTS (Flexible Alternative Transmission System) in the resolution of the problems related to the power flow in the AC transmission networks. In order to facilitate the understanding of this work, a comparative study of the performances of the two technologies between the UPFC (Unified Power Flow Controller) and RPI was carried out and at the end of which we were able to highlight the preponderance of RPI compared to the UPFC in the bypassing of the short-circuit fault insofar as the latter allows, in particular, an increase in the transformation capacity without an increase in the level of the short-circuit. The decoupled watt-var method has been used to control the UPFC while the RPI is controlled by phase shift. The simulation results are obtained in the Matlab Simulink environment and show the flexibility of the RPI compared to the UPFC in limiting strong contingencies.
