Abstract

The invention discloses a photovoltaic-energy storage joint power station optimal operation method considering a typical scene, which belongs to the field of photovoltaic-energy storage joint power station optimal configuration. A typical scene partitioning method based on an SOM clustering algorithm analyzes different typical operation scenes of the photovoltaic-energy storage joint power station; then, in consideration of generating profits, rewarding and punishment assessment profits and energy storage peak shaving and valley filling profits, a photovoltaic-energy storage joint power station typical scene profit optimization model is built; and finally, the model is used to analyze and discuss a profit optimal operation mode under the typical operation scene of the photovoltaic-energy storage joint power station. Example analysis shows that by using the typical scene analysis method and the profit optimization model, a battery energy storage system of the photovoltaic-energy storage joint power station can be reasonably optimized and configured, a correction operation mode is built, and the photovoltaic-energy storage joint power station can acquire the optimal economic profits.

Description

technical field [0001] The invention relates to a method for optimizing the operation of a combined optical-storage power station in consideration of typical scenarios, and belongs to the field of optimal configuration of a combined optical-storage power station. Background technique [0002] In the context of developing a low-carbon economy, China's recognition of renewable energy is getting higher and higher. Compared with conventional energy power generation, photovoltaic power generation has the advantages of safety, cleanness and sufficient reserves. It occupies an important position in renewable resources and has good development prospects. The related application technology has also been developed rapidly. [0003] Photovoltaic power generation has randomness and volatility. Large-scale centralized photovoltaic power station clusters cause changes in power generation, and their ability to adjust active power is weak, which will occupy a large amount of system backup r...
