研究目的
Investigating the use of selective harmonic elimination (SHE) modulation strategy and Tabu Search Algorithm (TSA) to optimize the performance of a three level solar inverter for standalone power system.
研究成果
This paper demonstrated the ability of the selective harmonic elimination strategy for multilevel inverters of producing high quality voltage waveform with less harmonics and maintain the fundamental component at a desired value, and also the possibility of using the Tabu Search Algorithm (TSA) to solve the optimal switching problem for multilevel inverters. The SHE would be a very ef?cient method to control solar DC to AC converters.
研究不足
The main disadvantage of the SHE method is that a set of non-linear equations must be solved to obtain the optimal switching angles to apply this strategy.
