چکیده مقالهSingle-stage Single-phase grid tied inverter (GTl) is one among types of inverters widely used in photovoltaic (PV) generation system due to the advantages such as ruggedness, reliability, and cost effectiveness they offer. In this paper a modified One-Cycle Control (OCC)-based GTi single-stage PV system is proposed which do not require the service of a phaselocked loop for interfacing the inverter to the grid. To ensure minimum total harmonic distortion (THD) level of injected current, parameters of the OCC and single-stage inverter are obtained using differential evolution (DE) optimization algorithm. The proposed strategy is simple, easily implementable, and robust against variations of sun irradiance. The viability of the proposed methodology is confirmed by performing MA TLABTM Software simulation and experimental validation.
