Description

technical field [0001] The invention belongs to the technical field of industrial control, and in particular relates to a wind-solar-storage integrated control system and method. Background technique [0002] Among the new energy sources, the development and utilization of solar energy and wind energy are increasingly sought after by various countries due to their inexhaustible, inexhaustible, local availability, no need for transportation, wide distribution, high reliability, no pollution, and good for ecology. It has become a new type of energy with the highest level of development and utilization, the most mature technology, the most widely used, and the most commercial development conditions in the field of new energy. However, both wind energy and solar energy have disadvantages such as low energy density and poor stability, which makes the independent wind power generation system and independent solar power generation system have the disadvantages of energy instability...
