Smart Grids (SG) enable power generation, distribution, transmission, customers and utilities to transfer, predict, monitor and manage energy usage effectively. In order to provide them, SGs need to be fully realized by integrating communication technologies infrastructures. Today, SGs have some main systems. These are Advanced Meter Reading (AMR), distributed renewable energy, energy storage, electric vehicle and smart city-home implementations. AMR is the most prominent SG component between all SG main systems. Because it provides to follow all consumers remotely and momentarily using their Smart Meters (SM). AMR system is based on SM, gateway, meter data management software and wired or wireless communication method. Nowadays, Power Line Communication (PLC) is the most popular wired communication method for remote meter reading because of try to use existing electric distribution grid infrastructure. On the other hand, GPRS/EDGE/3G is one of the widespread wireless communication method for remote meter reading implementations but its costly and external dependence has started the search for new communication methods instead. In this paper, practically twelve electric meters are tried to be read remotely with PLC in Yeşilırmak Electric Distribution Company field until the distribution transformer. These remote meter reading results that captured with PLC will evaluate in AMR software. Then an AMR system model is put forward thanks to this field implementation. Beside this a hybrid communication method has been suggested for smart metering. PLC key parameters will find out. In addition, data concentrator (DC), meter and gateway that has PLC features equipment field configurations will research.

Advanced Metering Infrastructure (AMI) consists smart meter, gateway, meter data management software. Smart meter and gateway work together to measure energy on the field. Then, gateway send the measured smart meter data that can be periodic or instant meter reading results, power factor, voltage-current-power information. In addition, gateway sends the information to the meter data management system whether there is energy or not by using a communication method in the field. If there is an integration between AMI and other distribution network systems like Outage Management System (OMS), Customer Relations Management, AMI provides measured data to these systems. Supercapacitor (SC) is a new type small energy storage device and it can easily use power system to provide the energy certain time in case of power failure. The gateway that is part of AMI connects the distribution grid physically on the field and provides own energy so when the power failure occurs in distribution grid at same time gateway energy will be cut. This means last measured data and last field situation can't be send to the AMI software so all system integration and remote meter operation will halt. This paper handles SC usage as a part of AMI system gateway on the field to provide last measured data to the AMI software. SC benefits are shown using AMI system with measured data in distribution grid. SC model will explain considering gateway design. Gateway with SC and gateway without SC situations will compare in terms of AMI and other system integrations.
