Problems solved by technology

[0006] 1. In the spot environment, medium and long-term transactions are carried out in accordance with the principle of voluntary participation of market participants, and there is no support for medium and long-term planning data
[0007] 2. The construction of the verification model needs to take into account both the market and the power grid, especially the scattered transactions of market behavior such as annual direct purchase of electricity, as well as the coexistence of transactional electricity and planned electricity, which lead to strong technical and policy aspects of medium and long-term safety verification , it is difficult to model
[0008] 3. The research object of the medium and long-term calibration model has a long time span, various constraints, and large calculation scale, etc.
[0009] Due to the constraints of the above-mentioned factors, in the prior art, the security verification method for medium and long-term transactions in the electricity market is still in the very early research stage, and practical application is almost blank

Abstract

The invention provides a safety checking method and device for long-term transactions in an electricity market and electronic equipment, and the safety checking method comprises the following steps: obtaining a transaction checking power flow section of a future power grid model according to the prediction of a power grid system and an operation state thereof in a transaction time range; according to the power grid operation safety constraint, constructing a transaction checking model satisfying the power grid safety margin and the power transmission channel capability; according to the transaction adjustment strategy and the security constraint of the electric quantity contract, constructing a transaction decision model satisfying different adjustment strategies so as to realize execution of the electric quantity contract; and according to the transaction checking power flow section, the transaction checking model and the transaction decision model, obtaining an output unit combination satisfying safe operation of the power grid, and realizing safety checking of long-term transactions in the electricity market. According to the safety checking method and device and the electronic equipment provided by the invention, the safety checking of medium and long-term transactions can be realized, the safe operation of a power grid is ensured, and the coordination of medium and long-term power grid operation and market operation is realized.

Description

technical field [0001] The present invention relates to the field of electric power market, in particular to a safety check method, device and electronic equipment for medium and long-term transactions in the electric power market. Background technique [0002] Since the trading organization and dispatching organization are relatively independent, it is impossible to estimate system information and operating constraints during the power trading process. In particular, the execution of medium and long-term electricity trading contracts is affected by future system load requirements, maintenance arrangements, and system operation constraints. Therefore, it must be checked to verify the enforceability of the power contract and ensure the safe and stable operation of the power grid. The construction of regional interconnected power grids can effectively solve the problem of unbalanced energy resources and load demand between regions, and deploy clean energy in a wider range. I...
