Fully tapping into the load regulation capacity of cascade hydropower stations on a river, in coordination with wind and photovoltaic power stations, can effectively suppress fluctuations new energy promote grid integration consumption energy. To derive peak shaving dispatching rules for cascaded provincial systems high proportion integration, short-term model was first established considering large-scale consumption; secondly, based statistical learning methods, response to were derived. Finally, taking farms, Qingjiang Hubei Province, China, as research objects, compensation effect output performance verified. The results indicate that reduce valley difference grids improve overall smoothness loads while suppressing output. After by hydropower, residual fluctuation indices are improved more than 20% compared those after probabilistic decisions facing period’s through optimal provide dispatchers richer decision-making support information have guiding significance actual dispatch stations.
