Embodiment 1

[0103] A decentralized power spot market transaction simulation method, the method is aimed at the simulation analysis of the power spot market in a typical summer day of 2017 in a province, and the following steps are followed in turn:

[0104] 1. Select August 8, 2017 as the typical summer load day of the province’s power grid (the load curve is composed of 24 load points), and establish a typical load daily transaction space model based on the actual power consumption of the typical day and the direct transaction of large users. , the establishment of a typical load daily transaction space model includes a demand space construction unit and a power sales space construction unit, and the construction method of the demand space construction unit is: first calculate the annual demand space according to the typical daily actual grid power consumption and large user direct transactions , and then calculate the daily demand space based on the annual demand space to be 56.43 millio...

Embodiment 2

[0122] The difference with embodiment 1 is:

[0123] Step 4 of this embodiment carries out sensitivity analysis by changing the coal price, and the results are shown in Table 3:

Abstract

A method for simulating transactions in a decentralized spot power market is disclosed. At first, a typical load daily trade space model is established accord to that actual power consumption and thedirect trade of large users on typical day, and then a decentralized spot market trading simulation model is established, the evaluation index system is established and different trading schemes are designed. Then the evaluation indexes of each trading scheme are calculated according to the trading simulation results. Finally, the trading scheme analysis and sensitivity analysis are carried out according to the evaluation indexes of each trading scheme to verify the rationality of each trading scheme and analyze the possible risks in the spot market of electric power. This design not only canscientifically and reasonably realize the effective simulation of spot market, but also can accurately reflect the trading reality of the spot market in the initial stage.

Description

technical field [0001] The invention belongs to the technical field of electric power market, and in particular relates to a distributed electric power spot market transaction simulation method, which is suitable for realizing the transaction simulation of electric power spot market. Background technique [0002] There are a large number of uncertain factors in the construction of the power spot market, which brings great difficulties to the operation decision-making of the power spot market. In order to resolve risks in the stage of scheme design and rule formulation, before the official launch of the power spot market, it is necessary to closely combine the actual power grid to simulate the transaction of the power spot market for research and verification of various power spot market schemes and rules. Reasonability and analysis of possible risks. This can not only provide an effective means of technical support for the training of traders of each market member before th...
