Application of power electronic converters in energy systems application have beenincreased due to the present national renewable energy portfolio. Photovoltaic, Battery Energy Storage Systems (BESS), Doubly Fed Induction Generator based Wind System, FACTS devices etc. are some of the applications in energy systems having power electronic converters. Power Electronic converters with its fast electronic switching and standard control configuration have low inertia compared to electro-mechanical device based energy systems. Motivation of this research work is to develop control system configuration with photovoltaic source as intermittent source and battery storage / ultra capacitor as energy storage unit as auxiliary source. Inverter of energy storage unit is integrated with synchronous generator emulator. This control unit helps in regulating power supplied or absorbed by energy storage unit to improve inertial response of photovoltaic unit. This unit is named as PVSG (Photo-voltaic Synchronous Generator) unit. In this work, dynamic characteristics of analytic model of PVSG unit is assessed and parameter sensitivity analysis is presented. Based on the results, few recommendations have been made for effective design of PVSG unit.
