Smart meter design with incorporated dynamic control of grid connected three phase inverter

摘要

In this paper, we proposed a smart energy meter prototype with the feature of three-phase inverter control that is supplied by a solar PV system and is connected to a grid. The inverter is controlled according to grid requirement and hence promotes the optimized penetrations of renewable to the grid. The smart meter designed has been incorporated with the feature of active and reactive power control. The controller is placed in the design of smart meter to eliminate the need of excess control system for controlling grid-connected inverters. This approach has been taken into account considering the need of inverter control for renewable integration in smart grid and hence including the control design in the smart energy meter can eliminate the use of excess equipment and also reduces the cost involved. This paper also describes the various literatures involved for control of grid connected inverter for non-ideal grid connections and also shows how the present system can be more efficient and cost effective for renewable integration with the grid system.
