Three Level Solar Inverter For Stand-alone Power Systems: Simulation And Practical Realization

Providing electrical energy for oil and gas extraction sites can be a real challenge especially for a large oil and gas company like Sonatrach. Solar energy can be great solution for this issue. This study presents an efficient way to convert electrical energy from DC to AC using a modulation strategy called selective harmonic elimination; this method will be used to optimize the performance of a three level solar inverter for standalone power system. Harmonic pollution is a very common problem in the field of power electronics, this problem can cause multiple problems for power converters and electrical devices and also reduce their lifespan, the (SHEPWM) modulation strategy allows the elimination of low order harmonics and also control the amplitude of the fundamental component of the output voltage spectrum. Simulation and experimental results are presented in this work.
