Harmonic Grid Connected in Matlab

Abstract:

Solar PV energy is one of the most promising renewable resources that use the abundant and free energy from the sun having clean, inexhaustible and environmentfriendly cyclic operations. However, the intermittent nature of the output power of PV systems reduces their reliability in providing continuous power to customers. Solar PV energy can be used mainly in standalone (off-grid) and grid connected system. A stand alone solar PV cannot provide a continuous supply of energy due to seasonal and periodic variations. Therefore, in order to satisfy consumer load demand, grid connected PV energy systems that combine solar energy and other conventional conversion units are becoming more popular in recent years. But, the fluctuations in the PV output power with climatic conditions might lead to undesirable performance of the electric network in grid connected system.
