A load aggregator profit allocation method based on an improved Shapley value

Abstract

The invention discloses a reasonable and effective load aggregator profit allocation method based on an improved Shapley value. The method comprises the steps that firstly, allowing a load aggregatorcomposed of interruptible loads, wind power and energy storage equipment to serve as a dispatching main body, wherein system dispatching calculates load power needing to be reduced by the load aggregator in each time period according to a load reduction curve submitted by the load aggregator on the current day; constructing a load aggregator quotation model by taking the highest system comprehensive revenue as an objective function; and finally, constructing a double-layer optimization model based on the improved Shapley value, taking the load aggregator quotation model as bottom-layer optimization, and taking member profit distribution maximization as an objective function in upper-layer optimization. According to the method, the relative income of the members is taken as an optimizationtarget, and through relative income balance, it is ensured that the members of the system obtain the excess income with the same proportion, so that the problem that in the prior art, the subjective satisfaction degree of market participants and the market contribution of the participants cannot be comprehensively considered is solved.

Description

technical field [0001] The invention belongs to the technical field of power systems, in particular to a method for apportioning profits of load aggregators based on improved Shapley values. Background technique [0002] At present, my country is actively promoting power grid reform, separating online sales, transmission and distribution, and breaking the current single power purchaser pattern has become one of the main directions of power reform. The document of the new power reform clearly states that users can voluntarily choose to sign composite agreements or contracts with power industry entities based on their own load characteristics to participate in power market transactions. Demand-side resources include active loads, energy storage equipment, and distributed power sources. [0003] Load aggregators can participate in the operation of the power market through different methods and strategies, allowing various types of demand-side resources to effectively participa...

Problems solved by technology

[0008] In view of this, the purpose of the present invention is to address the deficiencies in the prior art, to provide a load aggregator profit allocation method based on the improved Shapley value, and to take the relative income equality of members as the optimization goal, which has been considered in the traditional Shapley value method After the members make contributions to the system, through the relative income balance, each member of the system is guaranteed to obtain the same proportion of excess income, so as to ensure the stability of the member structure and the sustainable development of the system, and solve the existing technology that cannot comprehensively consider the market Subjective satisfaction of participants and the question of market contribution of individual players
