Based on testing results

a load distribution optimization among three home-made 300MW generating units in parallel operation was realized by means of the dynamic programming theory. The result shows

a great deal of coal consumption was economized by comparison with average load distribution. On the basis of analyzing and comparing several methods commonly used for load dispatch optimization

some problems of load economic dispatch in a power plant

such as acquisition of energy consumption characteristics

consideration of energy consumption in operation

start-up and shut-down

as well as the reliability in implementing load dispatch optimization etc.

were discussed.
