Performance Analysis Of Grid Tie Inverter With Power Limiter To Increase Utility Power Reduction In One Way kWh Meter Circuit

Abstract

The use of grid tie inverter (GTI) in household electricity is intended to reduce the use of electricity from utilities. The configuration of GTI usually does not use batteries and the excess power from PV will be sent to the grid so that it will substitute utility electricity with electricity from GTI. However, this can occur when follow net metering program by installing a export-import kwh meters (two-way kwh meter) or follow feed in tariff program. If the kwh meter used does not support this capability or not following both program, the electric power of GTI will not substitute power from the utility. GTI with power limiter allows the inverter to work like a GTI in general but does not send excess power to the utility. The excess power from PV can be stored into the battery so that when the power shortage of PV will be substituted with power stored in the battery is not from the utility. In this research, conducted a study of the performance of the GTI with a power limiter and compared it with the GTI without a power limiter that works on an electricity network. The results of the study show that the use of GTI with a power limiter can increase the reduction in power usage from utilities by up to 40%.
