The Plant's Optimal Load Dispatch And Unit Commitment Of Thermal Power Plant

Energy conservation is the important guarantee to the country's economic sustainable development.,doing research on the optimal load dispatch and unit commitment of thermal power plants to minimize the fuel consumption has practical significance.The paper focusing on the practical moving condition of the thermal power plants,studied in detail that how to determine the fuel consumption curve of unit and at the same time did the curve fitting according to the units data collected from Power Plant;studied the each fuel loss in the process of starting-stopping the units and their calculation methods,and set up the start-stop loss economical calculating model;and put forward that fuel consumption and life expenditure while starting and stopping the units should be considered when using peak-load regulation;built the mathematical model of plant's optimal load dispatch and unit commitment,and took several restrictions under consideration in the light of safe and economical units operation;by computing,fixing the critical time whether the unit is running in low load or a part is stop and the others are running in rating;and achieve the power plant optimal load dispatch by MATLAB;and designing the SIS's structure.
