Power energy volume contract transaction method under load-grid-source coordinated control mode

Abstract

The invention provides a power energy volume contract transaction method under a load-grid-source coordinated control mode. The method comprises steps of determining the member scope of a transaction market and the priority of a declared transaction; carrying out a centralized matching (bidding) transaction, determining the matching priority according to the declared power quantity-power price pair of each transaction participation party, carrying out "high-low matching" until validity conditions of matching termination are met, and obtaining the transaction compensation power price and the transaction power quantity of each participation party; determining power energy volume violation examination rules, and carrying out power examination and contract volume examination in contract execution under the load-grid-source coordinated control mode; and carrying out energy charge calculation and payment. The method is advantageous for promoting the enthusiasm of each source-load participation part to carry out the transaction by means of market-oriented means, the transaction mode with the characteristics of "daily electricity measurement monthly settlement" can truly realize the power balance between the new energy power generation and the load electricity, and the method is more able to adapt to the new energy output stochastic volatility, and further enhances the capability of new energy abandoned wind and light energy consumption.

Description

technical field [0001] The invention relates to the field of electric power market, in particular to a method for contract trading of electric power quantity under the coordinated control mode of the load-network source. Background technique [0002] Facing the increasingly serious energy crisis and air pollution, new energy enterprises represented by wind power and solar photovoltaic power generation have developed rapidly in recent years, and my country's wind power installed capacity has ranked first in the world. However, in major energy provinces such as Inner Mongolia, Gansu, Hebei, Jilin, and Xinjiang, which are important wind power bases, the phenomenon of curtailment of wind / solar power is becoming more and more serious due to insufficient peak-shaving capacity of the power grid, lagging grid structure and outbound transmission channels. The intermittency and randomness of nature have brought certain difficulties to the consumption. At the same time, as an importan...
