The Utility Interactive Inverter is a device that converts direct current (DC) electricity into alternating current (AC). Its main feature is the ability to synchronize and connect with a utility line. By utilizing the current line voltage frequency on the utility line, this inverter effectively maintains complete synchronization with the utility power, guaranteeing optimal output.
This is also called a Grid-connected Inverter that allows electricity to flow between a renewable energy source system and the utility system. When selecting a grid-interactive inverter, it is essential to consider the size of your battery bank and your intended utilization of grid electricity.
The proposed system is being controlled using a fuzzy PI controller. The operating point is used by this controller to determine the KP and KI gains. The inverter synchronizes its output current with the grid voltage, ensuring a rapid response time and minimal overshoot.
In order to function, an interactive inverter needs to be connected to an arbitrary waveform generator that emulates a utility source. By varying the voltage and frequency, the utility will measure the response of the interactive inverter.
