Title:       Seamless Operation of Photovoltaic Generation System in Connected to Grid/Remote Operation
Authors:   Sanjeev K Nayak, Saima J
Abstract:  The operation of photovoltaic (PV) based Distributed Generation (DG) system transition between grid connected and islanding is critical task. The changeover may also affect the system stability and reliability of the PV generation system due to very low inertia of the system. Hence, a suitable mechanism for transition between these modes to operate safely and reliably. The change in voltages and current will occur, which would completely outrage the entire power system as power system is dynamic in nature. Thus, to overcome these transition difficulties, this paper presents the two control strategies. The PV based DG works seamlessly by using these strategies, one is to works on current control mode during grid connected operation which is during normal operation and another is on voltage control mode that is during islanding/isolated operation. The intentional islanding algorithm and re-closure algorithm is presented in this paper.
