Research of Cascaded Hydropower Stations Short-time Optimize Dispatcher Based on Improvement A-NGA

The optimal operation of cascade hydropower stations is a high dimension, non-protruding, dispersed, non-linear dynamic optimization question, at present, though the researchers have put forward some methods to solve this question but always there are certain defects during the process of solving. This study analyses the characteristic of the niche genetic algorithm, direct against the question that the traditional niche genetic algorithm exists, and improve the niche genetic algorithm. This study proposed a kind of self-adaptation niche genetic algorithm with predator and applied it to solve the problem of cascade hydropower stations optimal operation. The result of the example shows that this algorithm can well solve the optimal operation problem of cascade hydropower stations which has high speed of operation and precision of solution.
