چکیده
Electric load forecasting has become crucial to the safe operation of power grids and cost reduction in production power. Although numerous electric models have been proposed, most them are still limited by poor effectiveness model training a sensitivity outliers. The limitations current methods may lead extra operational costs system or even disrupt its distribution network safety. To this end, we propose new hybrid load-forecasting model, which is based on robust extreme-learning machine an improved whale optimization algorithm. Specifically, Huber loss, insensitive outliers, proposed as objective function extreme learning (ELM) training. In addition, algorithm designed for ELM training, cellular automaton mechanism used enhance local search. verify our algorithm, some experiments were then conducted seven benchmark test functions. Due enhancement search, optimizer was around 7% superior basic. Finally, validated two real datasets (Nanjing New South Wales), experimental results confirmed that could achieve satisfying improvements both datasets.
