Frequency Stability Enhancement Using ANFIS Based Inverter Power Control in Low Inertia Power System

Abstract

Electricity generation is the process of generating electrical power from sources of primary energy. There are various methods of electricity generation on different types of energies. Among the source such as thermal power, nuclear power, or the renewable energies the cost of Generator electricity is relatively low. world wide ,about 20% of all electricity is generated by Generator power. Modern Generator turbines can convert as much as 90% of the available energy into electricity. In Tamil Nadu, there are 29 Generator power schemes having individual station capacity over 25MW aggregating to an installed capacity of 2,212.2 MW . At present there are 16 small /mini / micro Generator electric schemes with an installed capacity of 71.35 MW in operation in Tamil Nadu. In 2021, global installed Generator power electrical capacity reached almost 1400GW, the highest among all the renewable energy technologies. Generator electric power plant is usually built on a mountainous area and is isolated from the main power distribution system. It requires very efficient control strategy to control the speed of the Turbine in sudden variation and disturbance in the system. The main objective of this project is to develop mathematical model and design a ANFIS Logic Control (FLC) for Generator power plant during different fault schemes. In this project the ANFIS Logic Control (FLC) is used to control the frequency of the non- linear Generator power plant. The different types of fault models such as single phase ground fault and phase to phase fault are applied to the ANFIS Logic Control (FLC) Key Word: Solar panel, Wind Mill, Inverter, Frequency stability
