Now-a-days effective solar power generation is necessary for smart grid implementation. Grid fed single-stage single-phase solar inverter with incremental conductance MPPT (INC+ regulator), closed loop current and voltage controller is implemented. In normal condition inverter current T.H.D is under the limit as per ieee-519. At the time of fault, inverter having voltage imbalance, which may lead to damage. system fault ride through capability is improved by using Series Dynamic Braking Resistor (SDBR) with high current error as control parameter. Protection scheme maintains the grid code and hence the solar inverter needs not to be disconnected from the grid during the fault. Comparative results are obtained by simulation in MATLAB R2013a software. The whole system can be used in local distribution system as an application in future effectively.
