Abstract

The invention relates to the technical field of power dispatching, and discloses a virtual power plant day-ahead accurate peak clipping method, system and device and a storage medium. When the day-ahead peak clipping demand is received, the real-time power supply path of each user is obtained according to the user account data, each real-time power supply path is inquired according to the identifier of the heavy overload device in the day-ahead peak clipping demand, and if the heavy overload device is inquired in the power supply device set corresponding to the real-time power supply path, the real-time power supply path of each user is inquired in the power supply device set corresponding to the real-time power supply path. Taking the user corresponding to the real-time power supply path as a target user, constructing a target user set, initiating an invitation to each target user in the target user set, determining a bid-winning user according to the feedback of each target user for the invitation, and issuing a day-ahead scheduling plan curve to each bid-winning user, and each bid-winning user carries out peak clipping feedback according to the day-ahead scheduling plan curve. According to the method, the accurate peak clipping requirement on a certain main transformer, a distribution transformer or a feeder line can be met, and the peak clipping accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of electric power dispatching, and in particular, to a method, system, equipment and storage medium for precise peak shaving before a virtual power plant. Background technique [0002] Due to the large fluctuation on the power supply side, there may be power supply shortages in local time periods and local areas in the power grid. Peak shaving needs to be performed on the load side to maintain a real-time balance between power generation and power consumption. [0003] At present, when peak shaving is performed on the load side, invitations are usually made to all users in the region. It is impossible to accurately determine the scope of peak shaving invitations and achieve effective interaction with the corresponding users. Therefore, precise peak shaving cannot be achieved, and it cannot effectively solve the problem of heavy overload in local areas of the power grid. . SUMMARY OF THE INVENTION [0004]...
