Dual Mode Operation of PV-BES Based Microgrid with Seamless Transition Capability

With a need for the energy surety and improved power quality, a seamless power transfer capability for a grid interactive solar photovoltaic (PV) system is presented here utilizing a digital decimation filter. Moreover, with the rise in the need for power quality improvement is paramount and several steps are being undertaken for the utilization of an efficient control. Furthermore, in order to guarantee an improved PQ, the grid currents are analyzed in covenant with the IEEE-519 standard. For the operation in an off-grid mode, the power transfer is achieved through a voltage controller, which allows the satisfactory operation during standalone mode of operation. The corroboration of satisfactory system behavior is obtained during various weak grid conditions.
