Study On The Optimization System Of Load Dispatching In Thermal Power Plant

The research on the economic load distribution of the thermal power plant units is of great significance for improving the power plant's safety, economy and reliability. This article studied on a variety of methods in domestic and foreign for the economic load distribution, Genetic Algorithm was adopted because of its relative maturity and greater advantages in solving the high-dimensional optimization problems. A fitting method for the unit input output curves with the aid of Curve-fitting toolbox of Matlab was proposed. This article found out some factors that impact the economic distribute of the load and settled six different programs according to the including factors. By simulation and calculation for the six models, the best program was achieved so as to provide a theoretical basis for the thermal power plant unit's optimal operation.
