Bidding capacity determination method, system and device of virtual power plant and storage medium

Abstract

The invention belongs to the field of electric power automation, and discloses a bidding capacity determination method, system and device for a virtual power plant and a storage medium, and the method comprises the steps of obtaining the predicted power generation power and prediction error distribution of an uncontrollable power supply bidding day in the virtual power plant, and the maximum power generation power of a controllable power supply bidding day in the virtual power plant; according to the prediction error distribution of the uncontrollable power supply bidding day, obtaining a plurality of reserved capacities of the controllable power supply bidding day and deviation power of each reserved capacity; solving a preset generated power determination model to obtain the maximum profit of the virtual power plant participating in the power market and the generated power under the maximum profit under each reserved capacity; and obtaining the reserved capacity with the maximum profit of the virtual power plant participating in the electricity market in all the reserved capacities, and taking the generated power under the reserved capacity as the bidding capacity. The maximum participation of the actual power generation power of the uncontrollable power supply is realized, the wind curtailment amount and the light curtailment amount are greatly reduced, the consumption of clean energy is effectively promoted, and the overall power generation cost is reduced.

Description

technical field [0001] The invention belongs to the field of electric power automation, and relates to a method, system, equipment and storage medium for determining the bidding capacity of a virtual power plant. Background technique [0002] With the advancement of electricity market reform, a spot market has been preliminarily established. With the further development of the electricity market in the future, the electricity market will form a situation in which multiple markets such as the energy market, the reserve market, and the flexible peak-shaving market coexist. At the same time, as a virtual power plant with multiple power sources, its economic significance to participate in the electricity market is becoming more and more important. The technology for virtual power plants with multiple power sources to participate in the multi-type power market needs to be further explored. [0003] At present, when a virtual power plant including multiple power sources participa...

AI Technical Summary

Problems solved by technology

[0003] At present, when a virtual power plant including multiple power sources participates in the electricity market, the bidding capacity of wind power and photovoltaic power generation in the virtual power plant is usually the available power or guaranteed power consumption obtained from historical data. However, due to wind power and The output of photovoltaic power generation is uncertain. This method will lead to serious abandonment of wind and light, resulting in a serious waste of clean energy, which will lead to an increase in the overall cost of power generation.
