The invention provides a method and system for establishing a time sequence simulation model of a cloud energy storage operation mechanism, and the method comprises the steps: dividing demand side users into five types of users according to the load condition of the demand side, and providing different power supply combination modes for each type of users; obtaining the real-time electricity price of the user in the electricity utilization process, and obtaining the power supply relation between the user and cloud energy storage according to the real-time electricity price and the cloud energy storage time sequence charging and discharging strategy; and constructing a time sequence simulation model of the cloud energy storage operation mechanism according to the power supply combination mode, the cloud energy storage time sequence charging and discharging strategy and the power supply relationship. According to the invention, targeted discussion is carried out in combination with different types of users, a proper multi-energy storage equipment combination is arranged, and the power utilization cost is reduced while the power balance is ensured; a cloud energy storage time sequence simulation model is designed by considering important influence factors such as user electricity price and load capacity; charging and discharging conditions of multiple types of cloud energy storage under different working conditions are defined, and an optimal charging and discharging strategy of the cloud energy storage equipment is obtained.
Description
technical field [0001] The present invention relates to the technical field of power systems, in particular to a method and system for establishing a time series simulation model of a cloud energy storage operation mechanism. Background technique [0002] In recent years, renewable energy power generation technologies represented by wind power and photovoltaics have been rapidly developed and applied. These distributed energy sources are random, intermittent and volatile when they are connected to the grid. Mounting pressure. The access of distributed power to the distribution network leads to problems such as "low standards, weak connections, and low voltage" in the original power supply system. Contents of the invention [0003] In order to solve the above existing technical problems, the present invention provides a method and system for establishing a time series simulation model of the cloud energy storage operation mechanism, which fully reflects the actual situatio...
