Improving the Power Quality of Independent An UPQC-Based Hydropower Generation System

In this study, a new ALO-ANFIS method is used to improve the electrical performance of independent hydropower systems, which is essential for the efficient running of a UPQC. Hydropower producing systems encounter voltage and current imbalances when irregular loads are linked to them. In order to correct the distorted voltages, the SeVSC of the UPQC injects the required voltage in the power supply network. To maintain peak performance, the ALO algorithm keeps tabs on the system and tweaks the ANFIS settings as needed. Then the ShVSC reduces the current's harmonics. Moving forward, the overall quality of the electricity is enhanced. The simulation results show that the UPQC based on ALO-ANFIS successfully controls the DC-link voltage and keeps the load current and voltage constant. Sustainable and dependable power production is within reach with the help of the suggested control method
