Implementation of ANFIS in an Automatic Generation Controller of the Pico-Hydro Power System for Off-grid Rural Areas

Renewable energy sources play a vital role in the technologization of our modern world especially those who are in rural areas. However, the power system’s output voltage and frequency vary from time to time due to the continuous change in load, especially in pico-hydro. This study presents the Automatic Generation Controller (AGC) which will maintain the voltage and frequency output of the generator in the standard range stated in the Philippine Grid Code. Several sensors were used to measure the variations of the said parameters which are fed to the Arduino Uno that controls the water flow in the turbine through a chain system. The water flow determines the output frequency and voltage of the generator. ANFIS was implemented in the proposed AGC because it has the most reliable, fastest, and most efficient response among the four control algorithms for the automation of controlling the frequency and voltage output of the system in standard range of pico-hydro power systems. The AGC stabilizes the voltage and frequency output of the power system with an average time of 48.425 seconds. This study will provide great help in the renewable energy source industry making their products more reliable to be used in rural areas.
