To Control Load Frequency by using Integral Controller

Many different power frequencies were used in the 19th century. Very early isolated AC generating schemes used arbitrary frequencies based on convenience for steam engine, water turbine and electrical generator design. Frequencies between 16��? Hz and 133��? Hz were used on different systems. In this paper frequency deviation problem associated with load frequency control is evaluated. It is seen that Integral Controller is required to stable the frequency by properly selecting control parameters of the dual mode controller. The primary reason for accurate frequency control is to allow the flow of alternating current power from multiple generators through the network to be controlled. The trend in system frequency is a measure of mismatch between demand and generation, and so is a necessary parameter for load control in interconnected systems.
