Optimal Operating Method for Boiler, Turbine and Generator Considering Start-up and Shut-down Power Trajectories

Abstract

This paper presents an optimal operating method for the boiler, turbine and generator considering the start-up and shut-down power trajectories by a mixed integer linear programming problem. A boiler, turbine and generator unit commitment problem is a planning start stop states and inputs and outputs of boilers and steam turbines to minimize the total energy cost. In most of the conventional methods, the start-up and shut-down power trajectories have not been considered for the sake of simplification of calculation, etc. This optimal operating method for the boiler, turbine and generator can consider them by introducing a new set of binary variables and constrains which are operation mode discrimination constraints and power trajectory constraints.
