Supervisory Control And Data Acquisition system applied to a researching purpose microgrid based on Renewable Energy

Abstract

[EN] Control and data acquisition systems are required in researching facilities to analyze the behaviour of any process. In this paper, the results of the design and implementation of an automation and control system applied to a microgrid based on renewables energy are shown. The microgrid is located in the Laboratory for Distributed energy resources – LabDER at the Institute for Energy Engineering at UPV. The brain of the system is a PLC, programmed to carry out several tasks to guarantee the correct operation of the system. The measuring devices used are power meters, anemometer, temperature sensors and a solar cell to measure irradiance. The communication protocol used is Modbus TCP IP, Modbus RS-485 and Xanbus. All the information is centralized using a SCADA as an HMI. As a result, a robust control, and data acquisition system, able to manage a microgrid for researching purpose was obtained.
