Abstract—Reactive power injection in distributed generation inverters is an useful ancillary service for grid supporting purposes. For grid-feeding converters, the slope control method is the most common voltage regulation strategy used in local (communication-less). . This article presents a novel MPPT method for two stage PV inverters with a single phase connection to the power grid. The method takes advantage of the 100 Hz/120 Hz harmonic present on the DC-bus voltage to guide the MPP search. It consists of detecting the slope of the P-V curve and integrating it to obtain the duty-cycle. The power slope detector (PSD) is able to calculate the P-V slope to command the MPPT even. . Inverter-based distributed energy resources (DERs) such as photo-voltaics (PV) are becoming more commonplace in the distribution system. National Grid is experiencing record amounts of solar PV deployment within its service territories, creating an opportu-nity to operate a cleaner electric grid. . Inverter power can be controlled either by Bluetooth through the eConfigure CL125 APP or remotely using RS485 Modbus. If the grid voltage or grid frequency exceeds the thresholds specified by the grid operator, the grid-tied inverters must stop to feed in alternating current and disconnect from the utility grid in accordance with local. .
