Optimization of load frequency control in multi area power system considering tandem and cross compound turbine using fuzzy logic controller

Abstract

newline Electric power generation and consumption should perfectly go in hand if an electric energy system is to be stringently maintained in its nominal state characterized by nominal frequency, voltage profile and load flow configuration. In this project the responses of two area thermal-thermal and hydro-thermal power system is analysed with the presence of generation rate constraint, governor dead band, boiler dynamics, tandem single turbine, tandem double turbine, cross single and double turbine. Super Conducting Magnetic Energy Storage (SMES), Super Synchronous Series Compensator (SSSC) and Redox Flow Battery (RFB) unit are incorporated in order to reduce the vacillations during sudden load demand. The SMES is used which can effectively damp electromechanical oscillations in a power system, because they provide storage capacity in addition to the kinetic energy of the generator rotor, which can share the sudden changes in power requirement. Small rating SSSC units are connected in series with tie-line of the two area interconnected power system and response shows that they are capable of consuming the oscillations in area frequency deviations and tie-line power deviations of the power system. For an overload condition for short time period because of nature of RFB the extremely faster response is obtained.
