Reactive Power Control in the Deregulated Electrical Power Environment using FACT Devices

In the deregulating electricity market, many private sector power producers areparticipating actively. With growing number of the wind mills and solar power generation, the reactive power production will be more because of induction generator and inductive type load. Many blackouts havehappenedin the past decades due to more reactive power which lead to a decrease in the magnitude of real power. It is very essential to control and compensate the reactive power, increase the real power flow in the transmission line, increase the transmission efficiency, improve the system stability andbe in a safer place to save the fossil fuels for the future. In this paper the importance of reactive power and its various compensation and control techniques are applied to a five bus deregulated test case model. The simulations were done using Matlabsimulink, for various FACT controllers such as STATCOM,SVC,SSSCand UPFC compensationand the results were tabulated and compared.
