EXIM SMART METER UNTUK INTEGRASI ENERGI TERBARUKAN BERBASIS IOT

Smart grid is a power grid system that integrates user-generated renewable electricity sources such as solar panels and wind turbines with the company's main grid. This small generator is called a micro grid. A smart meter is one that is needed in the 4.0 revolution era to be able to control and find out the use of voltage, current, power and electrical energy used and integrate 2 energy sources at once from renewable energy (microgrid) with PLN (mainrid). The working principle of smart meters uses Kirchhoff's current law, a series of 3 branches, namely 2 inputs and 1 output branch, is used as the basis for developing smart meters. By using PZEM004T as an AC power sensor module that captures current, voltage, power, frequency, and power factor data, it is sampled and compared in each input branch using the Nodemcu microcontroller. For data acquisition of voltage, current, power and electrical energy stored through the Mysql database using IoT facilities without having to be where the tool is located. In this way, this smart meter can detect the direction of the electric power flow the customer is buying (importing), selling (exporting), or both. With its ability to perform two-way detection, apart from opening up various innovations in electricity services, this research can also contribute to accelerating the adoption of renewable energy in Indonesia
