Embodiment 1

[0052] Such as figure 1 As shown, the regional power market power purchase entity settlement system in this embodiment includes:

[0053] The data collection module 100 is used to collect the day-ahead electricity transaction declaration benchmark value, daily transaction transaction results, monthly bilateral transaction transaction results, and monthly centralized transaction transaction results of the power purchase entity; the transaction results include transaction electricity and electricity prices; Collect the monthly trading power generation of the power purchase entity corresponding to the transaction power plant;

[0054] The metering module 101 is used to measure the actual electricity consumption of the electricity purchasing entity, and the actual electricity consumption includes daily actual electricity consumption and monthly actual electricity consumption;

[0055] Deviation setting module 102, used to set the baseline value of the daily electricity consumptio...

Embodiment 2

[0061] The difference between embodiment 2 and embodiment 1 is: the daily electricity deviation baseline value setting c% and m 1 Two parameters; specifically: the part of the uncompleted day-ahead power trading volume exceeding c% of the daily trading volume is expressed in m 1 The price of yuan / kWh pays the deviation electricity fee, and the part within c% is exempted from the deviation electricity fee. Among them, 0

[0062] The baseline value of the monthly electricity deviation is set to d% and m 2 Two parameters; specifically: the part of the less power consumption exceeding d% of the transaction power in the transaction results of the monthly centralized transaction is represented by m 2 The price of yuan / kWh pays the deviation electricity fee, and the part within d% is exempted from the deviation electricity...

Embodiment 3

[0064] Such as figure 2 As shown, a settlement method for power purchase entities in the regional power market, using the settlement system for power purchase entities in the regional power market described in Embodiment 1, includes the following steps:

[0065] Step (1), data acquisition: through the data acquisition module, collect the day-ahead electricity transaction declaration reference value U rdN , daily transaction results, monthly bilateral transaction transaction results, monthly centralized transaction transaction results, and at the same time collect the monthly transaction power generation Q of the power purchase entity corresponding to the transaction rt ;

[0066] Step (2), measurement and deviation setting: measure the actual power consumption of the power purchase entity, including daily actual power consumption and monthly actual power consumption, and at the same time, set the daily power consumption deviation of the power purchase entity Baseline value ...

Abstract

The invention relates to a settlement system and method for an electricity purchase subject in a regional electricity market, and belongs to the technical field of electric power systems. The system comprises a data collection module, a metering module, a deviation setting module, a day-ahead electricity settlement module, a monthly bilateral settlement module, a monthly centralized trading settlement module and a summarization settlement module. The system is novel in structure; the settlement process is reasonable and efficient; and through electricity price competition permission and electricity distribution and selling subject permission, effective technical support is provided for gradually nurturing multiple marketized competition patterns, breaking the monopolistic situation of a power grid company and forming an advanced electricity utilization transaction settlement mechanism.

Description

technical field [0001] The invention belongs to the technical field of electric power systems, and in particular relates to a settlement system and method for a power purchase subject in a regional power market. Background technique [0002] At present, in the electricity market, there is great resistance to the transaction monopoly of electricity purchasers, and the electricity transaction mechanism has basically not been formed, and the effective transmission mechanism of prices, costs, and profits in each link has not been formed; the issue of dispatch independence is not clear, and there are many restrictions on transaction independence. [0003] With the proposal of the new electricity reform plan, how to break the monopoly of power grid companies and gradually cultivate a diversified market-oriented competition pattern through reforms such as liberalization of competitive electricity prices and distribution and sales entities has become a top priority. Further, in the i...
