Abstract

The invention provides a method and system for bidding and profit distribution of a virtual power plant considering the uncertainty. The method includes the steps of establishing, based on a multi-agent model, a distributed power supply bidding strategy within a virtual power plant considering the uncertainty and independence; establishing, according to the distributed power supply bidding strategy within the virtual power plant, a virtual power plant benefit distribution strategy of an improved Shapley value based on risk factors; and validating the virtual power plant benefit distribution strategy. The method and system for the bidding and profit distribution of the virtual power plant according to the invention participate in the bidding of the power market with the goal of maximizing the overall profit on the basis of guaranteeing the load demand and standby demand of the virtual power plant, and at the same time ensure the stability of the cooperation of various distributed powersupplies within the virtual power plant.

Description

technical field [0001] The present invention relates to the technical field of market transactions of electric power systems, that is, scheduling operation, and in particular, to a virtual power plant bidding and profit distribution method and system considering uncertainty. Background technique [0002] With the continuous growth of electricity demand and the increasingly serious problems of energy shortage, environmental pollution and climate change on a global scale, the disadvantages of traditional energy power generation have become increasingly prominent, and renewable energy has become the mainstream trend of energy development. The virtual power plant aggregates various types of distributed power sources such as uncontrollable units, controllable units, energy storage systems, and controllable loads through advanced control, metering, and communication technologies. To accommodate the randomness of distributed power output, realize the coordinated and optimized opera...
