Problems solved by technology

Therefore, this method cannot reflect the real network loss influencing factors of the power plant, and is not conducive to realizing optimal allocation of resources by adjusting network loss allocation and improving power grid operation efficiency
[0004] Algorithms such as power flow tracking and Shapley value proposed by academic circles are closely integrated with grid operation, but their calculation process is closely integrated with grid operation technology, which is not conducive to market members' understanding of its physical principles, and it is difficult to implement them in practice

Embodiment Construction

[0037] In order to better understand the present invention, the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0038] Such as figure 1 As shown, a power spot market centralized bidding network loss allocation algorithm based on the improved Shapley value includes the following steps:

[0039] S1: To count the actual network loss, the transaction target in the power spot market is the power at a certain moment in actual operation, so the allocation of network loss in the power spot market only needs to consider its power. The actual network loss is the difference between the on-grid power of all power plants connected to the transmission network and the power supply load of the transmission network and the external transmission load at that moment, specifically as follows:

[0040]

[0041] in, is the actual network loss at time t, is the on-grid power of power plant i at time t, is the power suppl...

Abstract

The present invention relates to the technical field of electric power spot market, in particular to an algorithm based on improved Shapley value-based centralized bidding network loss allocation in electric power spot market; the present invention can take into account market members' requirements for intuitive calculation methods and the combination of allocation algorithm and network loss contribution rate According to the demand, the improved Shapley value is used to reflect the actual contribution of the power plant to the network loss. By improving the Shapley value algorithm, it is simplified to make the calculation process more intuitive and easy to understand. Compared with the Shapley value and power flow tracking algorithm , the physical meaning is clear, the calculation process is simple, and it is easy for market members to accept.

Description

technical field [0001] The invention relates to the technical field of the electric power spot market, in particular to an algorithm for allocating network loss in centralized bidding in the electric power spot market based on an improved Shapley value. Background technique [0002] The power spot market is the focus of the current power market reform, and the centralized bidding transaction mode is the most commonly used trading mode in the power spot market. In this mode, the power plant declares the power capacity and quotation according to the power demand at a certain moment, and the power dispatching organization takes the economical operation of the power grid as the goal, comprehensively considers various constraints such as network transmission, and decides the winning power of each power plant, and then determines the clearing. electricity price. Network loss allocation is an important issue in the power spot market. Reducing network loss is an important decision-...
