[0079] Such as figure 1 As shown, this embodiment provides a source-network-load-storage interactive transaction method based on price incentives, including the following steps:
[0080] S1: Conduct access qualification review for electricity sellers and purchasers participating in the source-grid-load-storage, and allow interactive transactions after the access qualification review is passed.
[0081] Specifically, in the qualification review, the entry requirements of the electricity seller are: the new energy power generators in the electricity sales area of the electricity seller that are qualified for direct transactions;
[0082] The access requirements of the power purchaser are: the power users in the power consumption area of the power purchaser are qualified for direct trading, and the power users have the conditions for electricity collection (such as 15 minutes).
[0083] S2: When the interactive transaction is in progress, conduct an auction including the lis...

Abstract
The invention relates to the technical field of electric power automation, and provides a source network load storage interactive transaction method and system based on price excitation, and the method comprises the steps: carrying out the listing and picking of a first stage and a second stage to auction the electric quantity when the interactive transaction is carried out; after the interactive transaction is carried out, the electricity purchasing party carries out daily decomposition on the electric quantity obtained by the transaction according to the new energy processing prediction to obtain a daily target control curve; outside the interactive transaction time, the new energy power generator and the traditional power generator perform contract transaction through transaction types including medium-and-long-term market transaction and day-ahead market transaction; and after the time specified by the contract is over, the transaction center determines the electricity price according to the implementation degree of the electricity purchasing party for the daily target control curve and performs clearing. Adjustable resources on a user side can be mined through a marketization means, flexible and diverse transaction means are provided, and source network load storage interaction is guided, so that the new energy utilization rate is increased, and the peak regulation pressure of a power grid is reduced.
Description
technical field [0001] The invention relates to the technical field of electric power automation, in particular to a method and system for interactive transaction of source-network-load-storage based on price incentives. Background technique [0002] In recent years, the installed capacity of new energy will continue to grow. In the case of high penetration of new energy, the power supply is abundant but the power shortage is becoming more and more serious. [0003] In the traditional power system, it is mainly "source follows the load", and the power generation company arranges and adjusts the power generation plan according to the load situation. However, such a method is difficult to adapt to the high uncertainty of new energy power generation, it is difficult to mobilize the enthusiasm of all users, and it is impossible to fully tap the potential of the demand side. [0004] In the context of the current reform of the electricity market, an effective market mechanism is...
