Method and device for ensuring capacity distribution of wind-light-water complementary power generation system containing hybrid pumping and storage

The invention discloses a hybrid pumped storage-containing wind-light-water complementary power generation system guarantee capacity distribution method and device, and the method comprises the steps: firstly building a hybrid pumped storage-containing wind-light-water complementary power generation system guarantee capacity calculation model; determining constraint conditions, and taking the maximum continuous generating capacity of the system in the scheduling period as an objective function; secondly, by taking the maximum contribution, the minimum contribution, the residual capacity and the cooperative willingness vector of the guaranteed capacity as characteristic indexes, constructing a guaranteed capacity distribution model based on an improved tau value method, and realizing a fair and efficient distribution target of the increment benefit of the guaranteed capacity; the improved tau value method is based on the calculation principle of a traditional tau value method, the alliance cooperation will is
