Problems solved by technology

However, since most of the electricity used by residents is purchased from grid companies in day-ahead transactions, these two methods that only allow residents to conduct end-to-end transactions in real-time transactions largely limit the on-site consumption of new energy. quantity

Embodiment

[0075] In this example, if figure 1 As shown, before the electric energy spot trading market opens (that is, before 7:00), residents will obtain the daily power generation and daily power consumption forecast information of the trading day. When the current trading is open (i.e. 7:00 to 17:00), residents use each hour as a trading time interval, such as figure 2 The three-stage transaction method shown in the preceding transaction; when the real-time transaction is open (i.e. 8:00 to 18:00), the residents use the real-time end-to-end transaction method proposed by the present invention to take one hour as a real-time transaction Trade at time intervals to resolve emergencies that occur in real time.

[0076] In the following, we will describe in detail an end-to-end power trading method for community residents facing the spot market of the present invention, which specifically includes two steps: S1, community residents determine the planned transaction relationship through ...

example

[0199] The present invention mainly adopts an embodiment, by comparing four different end-to-end power trading methods of community residents as shown in Table 2, that is: 1) community residents only conduct end-to-end power trading in real time; 2) Community residents only conduct end-to-end power trading through the pre-time plan; 3) Community residents first determine the transaction relationship through the pre-time plan without transaction volume adjustment, and then conduct end-to-end power trading in real time; 4) Community residents use this The description method carries out end-to-end electric energy trading, and illustrates the effectiveness of a spot market-oriented community resident end-to-end electric energy trading method of the present invention.

[0200] Table 2 is a detailed description of four different methods

[0201]

[0202] This example is based on a community micro-grid containing 21 households. Table 3 shows the specific number of various types of...

Abstract

The invention discloses a community resident end-to-end electric energy transaction method for a spot market. The method starts from two stages of time-ahead transaction and real-time transaction in the community resident electric energy spot transaction market. Community residents determine a planned transaction relationship through hour-ahead trading, carry out real-time end-to-end electric energy transaction according to the planned transaction relationship, in the specific transaction process, residents are promoted to provide auxiliary services to improve on-site consumption of new energy, in this way, economic benefits of community residents are guaranteed, and the electricity utilization stability and reliability of the community residents are further improved.

Description

technical field [0001] The invention belongs to the technical field of smart grids, and more specifically relates to a spot market-oriented end-to-end power trading method for community residents. Background technique [0002] A spot market generally refers to a real-time market for immediate physical delivery of a commodity. However, considering the instantaneous supply and demand balance characteristics of electricity commodity delivery, the time range of the electricity spot market is often extended to several hours or even a day before real-time delivery. The literature "Xia Qing, Guo Wei. Power market trading system with coordinated operation [J]. China Electric Power, 2009, 42(1): 1-6" pointed out that because the power spot market has (1) can be formed and the physical operation of the system Adaptive and optimized trading plan according to the wishes of system market members; (2) can realize efficient and optimal allocation of power resources; (3) can reduce system s...
