Optimal Algorithm of Load Assignment of Pipe-main Scheme Boilers Based on PSO

Because of the big difference in operating characteristics among pipe-main scheme boilers,it is a problem frequently encountered in the operation and management of pipe-main scheme plants that how to optimize the load assignment among boilers for a higher coal saving ratio.This paper presents a new optimal algorithm for load assignment—PSO which is different from the equal-rate criterion commonly used.The calculation results of an actual example demonstrate that the PSO algorithm is better than equal-rate criterion in saving coal.
