Implementation of Smart Grid System for Alternative Energy Power Plants Sources

Electrical energy is included in the most essential needs and cannot be separated from human activities. The electrical energy produced is still dominated by power plants by conventional energy sources so that the use of alternative energy is needed to prevent the limitation of energy sources. Alternative energy that is often used is a source of solar electricity that produces electricity by utilizing sunlight. In an effort to increase and utilize renewable energy sources, researchers seek to design and implement a smart grid system on alternative energy sources. The smart grid system allows users to monitor and control the energy used by analyzing the direct parameters to be assessed. Using this smart grid system can help overcome limitations in monitoring because it can be done remotely. This system uses the ACS712 sensor to detect the current at the DC load, and the PZEM004T sensor for the AC load. It communicates via an IoT-based internet network using ESP 32 with the percentage of errors obtained in the power dc load test resulting in an error rate of 0.012% and in the power AC load testing of 0.064%.
