In this paper a Mixed Integer Dynamic Optimization (MIDO) framework is exploited for combined Unit Commitment and Economic Load Scheduling (UCELS) optimization of power plants. Economic load scheduling optimization problem is formulated as a Dynamic Optimization (DO) problem that allows us to optimize the plant operations by taking into account the time varying dynamics. Dynamic optimization pr...

Conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. In the recovery system, super-critical an CO2 is employed as the working fluid operating in a Brayton cycle. Low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes th...

Program is a joint effort between government and industry to develop a new generation of coal utilimtion processes. In 1986, the Ohio Power Company, a subsidiary of the American Electric Power Service Corporation (AEP), was awarded cofunding through the CCT program for the Tidd Pressurized Fluidixed Bed Combustor (PFBC) Demonstration Plant located in Brilliant, Ohio. The Tidd PFBC unit began op...

Performance of a gas turbine is mainly depends on the inlet air temperature. The power output of a gas turbine depends on the mass flow rate of air. Now days the atmosphere temperature is hot, so the air is less density, the mass flow rate will reduce and automatically the power output will reduce. A reduce of 1°C temperature of inlet air increases the power output by approximately 0.7MW. To re...

In this study, effect of energy price on the development of a biomass gasification-solid oxide fuel cell-gas turbine hybrid power plant has been considered. Although, these hybrid systems have been studied based on sustainable approaches, economic aspects, specifically conventional energy prices, which are the principal bottleneck for the development of these new power generators, have attracte...

In this paper, ‎the multi-sensor fault diagnosis in the exhaust temperature sensors of a V94.2 heavy duty gas turbine is presented‎. ‎A Laguerre network-based fuzzy modeling approach is presented to predict the output temperature of the gas turbine for sensor fault diagnosis‎. Due to the nonlinear dynamics of the gas turbine, in these models the Laguerre filter parts are related to the linear d...

The significant penetration rate of wind turbines in power systems made some challenges in the operation of the systems such as large-scale power fluctuations induced by wind farms. Gas-fired plants with fast starting ability and high ramping can better handle natural uncertainties of wind power compared to other traditional plants. Therefore, the integration of electrical and natural gas syste...

The paper addresses the unit commitment problem in power plant operation planning. For a real power system comprising coal and gas red thermal as well as pumped storage hydro plants a large-scale mixed integer optimization model for unit commitment is developed. Then primal and dual approaches to solving the optimization problem are presented and results of test runs are reported.
