Problems solved by technology

Its existing measures generally use the combination of various forms of power generation equipment to generate synchronous high-efficiency power generation. However, the existing multi-form synchronous power generation equipment such as photovoltaic and wind power combination equipment is difficult when photovoltaic power generation cannot be performed during the day or cannot be generated at night. An integrated energy storage structure is formed through structural advantages, and its energy storage structure cannot be switched flexibly and intelligently. The energy storage effect is relatively general, and the energy utilization rate and storage rate are poor.

[0003] In order to overcome the deficiencies of the existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a source-network-load-storage integrated dispatching system for a carbon-electricity integrated virtual power plant [application number: 202111224641.1], which solves the technical problem that the real-time prediction of the user end and the production end cannot be performed in the existing technology, and predicts the consumption end and the power supply end to prevent the output fluctuation of the consumption end from fluctuating greatly or the input efficiency of the power end. Unable to supply power in time or the power supply cannot be replenished in time, resulting in a decrease in the quality of use of users at the consumer end, and at the same time reducing the supply efficiency of the power end; predicting the power output of the consumer end, effectively collecting power output to prevent peaks, and increasing the difficulty of grid operation. At the same time, power collection is also used as a condition for virtual scheduling, which improves the accuracy of virtual scheduling, and causes inconvenience to users due to insufficient power supply

However, this solution cannot solve the problem of multi-form synchronous power generation, and forms an integrated energy storage structure through structural advantages. The energy storage structure still cannot be switched flexibly and intelligently, and has the defects of general energy storage effect, poor energy utilization rate and storage rate.
