Distributed power transaction risk self-balancing method, system, medium and equipment

Abstract

The invention discloses a distributed power transaction risk self-balancing method and system, a medium and equipment. The method comprises the following steps: constructing a coordination utility function of buyers and sellers; establishing a coordination optimization method of buyers and sellers by considering standby purchase of mobile energy storage suppliers and balancing deviation punishment of the market; obtaining a distributed power transaction risk self-balancing optimization model by taking full social benefit maximization as a target, dividing the distributed power transaction risk self-balancing coordination optimization model into two stages, considering the maximization of total social welfare in the first stage, considering the minimization of deviation penalty in the second stage, and obtaining a distributed power transaction risk self-balancing settlement result considering deviation punishment through end-to-end negotiation. The distributed power transaction risk self-balancing method is suitable for multilateral market transactions with a large amount of distributed energy and more random loads, the default risk caused by contract deviation is effectively reduced, and the distributed power transaction risk self-balancing method has important significance for multilateral market transactions with deviation punishment.

Description

technical field [0001] The invention belongs to the technical field of electric power market, and in particular relates to a risk self-balancing method, system, medium and equipment of distributed electric power transaction. Background technique [0002] Increase in distributed energy resources and flexible loads has led market players to seek more aggressive market strategies. These emerging active market participants have changed the traditional electricity market structure, always pursuing the maximization of social welfare. The design of a proper new settlement system will facilitate the consumption of distributed energy resources and increase the flexibility of the power system. Peer-to-peer marketplaces have proven to be an effective mechanism for stimulating local transactions. Peer-to-peer trading is a protocol for exchanging products or information between two peers, and its main goal is to encourage market participants to trade with each other and maximize utilit...

Problems solved by technology

[0004] However, it remains a challenge for aggregators to combine internal resource management strategies with backup buying strategies during the end-to-end negotiation process

In order to achieve a balance between economy and transaction reliability in the distributed bargaining process, the transaction settlement model will contain a series of variable coupling constraints, which makes traditional distributed algorithms unable to directly solve this problem
