SCADA Systems Design to Optimize and Automate Microgrids Systems in Indonesia

Microgrid system is a solution to meet the electricity needs in remote, underdeveloped, and outermost areas in Indonesia. Until now, there are several installed microgrid systems in Indonesia and the numbers are increasing. Most microgrid system in Indonesia does not have remote capability which means that the control and monitor of system functions are carried out manually and locally. This problem might cause the system itself become not responsive to the any change and difficult to maintain, thus shorten the life of microgrid assets (e.g. battery, inverter, etc.). The purpose of this research to improve microgrid system by creating remote control and monitor capability using cross-protocol communication between devices in a microgrid system and implementing an energy balance control based on frequency reading automatically. In order to satisfy the objectives objective of this research, a Supervisory Control and Data Acquisition (SCADA) Master Station was designed and be equipped with Human Machine Interface (HMI) which able to control microgrid system equipment using the Modbus and IEC 60850-5-104 protocols. Based on the experiment result, the proposed SCADA Master station program was successfully carried out telecontrol, tele-information, and telemetering through the two communication protocols above. The proposed energy balance control interface was also successfully carried to deliver its purpose through the SCADA system automatically.
