Unformatted text preview: EEL 6266 Power System Operation and Control Overview of the Course 2008 Florida State University EEL 6266 Power System Operation and Control 2 Course Scope Topics power generation characteristics economic dispatch: thermal unit dispatch transmission system effects: transmission losses unit commitment generation scheduling with limited energy supplies hydro-thermal generation coordination production cost modeling automated generation control interchange of power power security and state estimation optimal power flow techniques EEL 6266 Power System Operation and Control Chapter 2 Characteristics of Power Generation Units 2008 Florida State University EEL 6266 Power System Operation and Control 4 Characteristics of Steam Units Model of a simple boiler-turbine generation unit Boiler generates steam to drive a single turbine-generator set Power produced from the burning fuel supplies the electric power grid and the auxiliary power system of the power plant steam power plants typically require 2% to 6% of the gross output from the unit for the auxiliary services Boiler Fuel Input Turbine Gen. Gen. Electric Grid Auxiliary Power Supply 2008 Florida State University EEL 6266 Power System Operation and Control 5 Input-Output Characteristics Terms used H = heat input to the unit energy per hour common units: MBtu / hr F = fuel costs times H cost per hour common units: $ / hr Input / output characteristics shown either with fuel cost or heat input output is the net electrical output of the unit constrained by minimum and maximum loading minimum is usually 30% of rated capacity necessary for flame stability and proper cooling of the heating tubes Input, H [MBtu/hr] Output, P [MW] Steam Turbine Generator Input-Output Curve P min P max P H P H Input, H [MBtu/hr] Output, P [MW] Steam Turbine Generator Input-Output Curve P min P max P H P H 2008 Florida State University EEL 6266 Power System Operation and Control 6 Incremental Heat Rates Incremental heat rate characteristic the first derivative of the input / output characteristic expressed in either H / P or F / P typical units: Btu / kWh or $ / kWh used in economic dispatching of units frequently this characteristic is approximated by a sequence of...
