Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Please refer to figure 1 , the present invention provides a power spot market clearing method that considers user demand response, and adopts the power balance unit transaction mode to solve the settlement and clearing problem in the power spot market, so as to improve the clearing efficiency of the power spot market and ensure the security of the system Stable operation; the method implementation steps are as follows:

[0026] Step S1: Take the medium- and long-term contract electricity generated by scheduling decomposition and the planned electricity not included in the market competition as the boundary conditions for day-ahead market transactions;

[0027] Step S2: Organize the participating members of the electricity spot market to form a power balance unit. The power balance unit is used as the unit. Before the day-ahead market transaction...

Abstract

The invention relates to an electric spot market clearing method considering user demand response. The method comprises the following steps of S1, presetting a boundary condition of a day-ahead markettransaction; s2, collecting an output / consumption plan and an unbalanced service quotation of the power balance unit; s3, clearing the electric power spot market according to the network security constraint, and if the output plan is greater than the consumption plan, enabling the electric power transaction center to clear out the electricity selling balance unit; if the output plan is smaller than the consumption plan, enabling the power transaction center preferentially to clear out the electricity selling balance unit and clear out the electricity utilization balance unit to determine a next-day power grid operation scheme; obtaining a day-ahead market clearing result; and S4, enabling the scheduling department to arranges unit output according to the day-ahead market clearing result,and carry out real-time market transaction and real-time market clearing at the same time. By introducing a power balance unit transaction mode and combining a method considering user demand response,synchronous transaction and smooth clearing of the power generation side and the user side in the spot market are realized.

Description

technical field [0001] The invention relates to the field of electric power spot market mechanism, in particular to a method for clearing the electric power spot market considering user demand response. Background technique [0002] China has started a new round of power system reform, and the construction of the power market is rapid. Provinces have established power trading centers and carried out a large number of annual and monthly medium and long-term power transactions. With the gradual deepening of power system reform, the construction of a spot market trading system consisting of a day-ahead market and a real-time market has become a hot issue in the construction of China's current power market. The power spot market can fully realize the balance of market-oriented power and electricity, give full play to the role of the power market in optimizing the allocation of power resources, and restore the attributes of power commodities. It is an important part of the power ...
