Abstract

Reliable and protected solar inverter is necessary for effective smart grid implementation. Grid fed hybrid singlestage single-phase solar inverter with incremental conductance MPPT (INC+regulator), closed loop current and voltage controller is implemented here. In normal condition inverter current T.H.D is under the limit as per IEEE-519. In this paper, Anti-islanding protection is achieved by using high speed AC circuit breaker, as per the guideline of German VDE0126-1-1 Standard. Also reliability is improved by using proposed hybrid solar inverter system. Comparative results are obtained by simulation in MATLAB R2013a software. The whole system can be used as a strong chain in local distribution system as an application in future effectively.
