Embodiment Construction

[0063] Below in conjunction with accompanying drawing, the technical scheme of the present invention is described in further detail:

[0064] like figure 1 shown,

[0065] (1) Demand side

[0066] a. Prosumer status

[0067] Suppose that in a period, each prosumer can only be a seller or a buyer, and cannot have both identities at the same time. Set in time period t, the prosumer p on the demand side i The energy supply (i.e. capacity) and demand (i.e. consumption) of , respectively, are and then the prosumer p at this moment i The net energy held in period t can be defined as follows:

[0068]

[0069] In formula (1), if the prosumer p i net energy It means that the prosumer has energy redundancy in the t period, that is, the identity is the seller (denoted as ). Conversely, if It means that the prosumer has energy shortage in the t period, that is, the identity is the buyer (denoted as ).

[0070] b. Prosumer Quote Model

[0071] In the process of ene...

Abstract

The invention discloses a P2P (Peer-to-Peer) transaction model based on a demand side, a load aggregator and a microgrid. In the framework, the invention provides a double-layer P2P (Peer-to-Peer) transaction structure. In the first layer, a user in a demand side can autonomously select a transaction object on the premise of meeting a transaction condition so as to promote an energy transaction; in the second layer, the users can clear energy in the local micro-grid market through the load aggregator. According to the invention, on the premise of guaranteeing the network security, the problem of unbalanced supply and demand of users can be effectively solved, the user-load aggregator-social benefit optimization is realized, and the energy utilization rate of the user / society is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of electric power and energy, in particular to a P2P transaction model based on demand side-load aggregator-microgrid. Background technique [0002] With the popularity of distributed energy and the proliferation of prosumers, how to manage the production and consumption of energy is an urgent problem to be solved. In this context, P2P energy trading emerged as a new concept. P2P energy trading takes into account the differences between prosumers and allows users to trade directly, forming a reasonable transaction price through competition, creating favorable conditions for users to quickly reach a balance between supply and demand, and providing a new paradigm for building a demand-side operation and management model . [0003] However, distributed energy usually belongs to different subjects, and each subject makes independent decisions to maximize their own benefits, which can easily lead to inconsisten...
