And after all the lists are confirmed to be generated, pushing marketing operation is carried out.

Secondly, preparing settlement basic data:

before the settlement of the monthly wholesale transaction user is executed, a settlement worker of the electric power transaction institution logs in the system to prepare settlement basic data. In the aspect of transaction data, transaction data of the transaction system is pulled, and after pulling, all electric power marketized transaction data and collected transaction data of the electricity purchasing main body are obtained, wherein the transaction data comprises daily transaction data and monthly transaction data (including monthly bilateral transaction, continuous listing, prior contract transfer and deviation electric quantity transaction), and all the data comprise electric quantity and electric price data; in the aspect of accounting data, actual electricity consumption data of an electricity purchasing main body is obtained through an interface with a marketing system, and the actual electricity consumption data comprises user basic information (user name, user number, metering point number and electricity consumption type), electric quantity (constant electric quantity, peak electric quantity, flat electric quantity and valley electric quantity), electricity price codes, work order numbers, business types, electricity consumption electric charge, basic electric charge, electricity dispatching electric charge, fund summation and electricity charge of users; in the aspect of daily metering data, business personnel can check daily metering data of daily transaction users transmitted by a metering system; in addition, settlement parameters including time-sharing floating coefficient, power transmission and distribution price and deviation electric quantity reference price are required to be configured. Through the steps, all settlement basic data required by settlement execution of the wholesale transaction user are prepared.

Thirdly, the wholesale transaction user performs settlement and results are filed:

after the settlement basic data is prepared, the settlement service personnel can perform settlement execution operation. The settlement algorithm is configured firstly, and adopts a mode of 'paying for nothing' including contract settlement, deviation electric quantity settlement, unbalanced electric charge settlement and time-sharing extraction charge settlement. The contract settlement is the product of contract electric quantity and contract electricity price, the deviation electric quantity settlement comprises the settlement of the less-used deviation electric quantity and the settlement of the over-used deviation electric quantity, the unbalanced electricity fee settlement is subjected to deviation assessment according to a settlement rule and is brought into unbalanced funds, and the time-sharing extraction cost settlement is calculated by using the actual electricity consumption and the time-sharing extraction coefficient. After the algorithm configuration is finished, settlement execution operation can be carried out, and electric charge settlement is carried out on wholesale transaction users, wherein the settlement execution of an electricity selling company and the settlement execution of wholesale power users are included, wholesale market transaction electric charge and electric energy discount price data are obtained after the settlement execution of the electricity selling company, and the electric energy discount price is the ratio of market transaction electric charge to total electric consumption. After the settlement of the wholesale power consumer is executed, the data of electric energy calculating fee, electric energy discount price and market-oriented to-house electric charge are obtained, and the market-oriented to-house electric charge is the sum of the electric energy calculating fee, the transmission and distribution electric charge, the basic fee, the power dispatching electric charge, the fund and the additional fee.

After the settlement is finished, the settlement data of the electricity selling company is filed so as to be used when the retail user settles the account later.

before the monthly retail user settlement is executed, the settlement staff of the electric power transaction institution logs in the system to carry out data preparation work of the retail user settlement, wherein the data preparation work comprises the preparation of package transaction information of the retail user and financial data of the retail user. The retail user package transaction information comprises package transaction information of a class A retail user (the contracted power-selling company settles with the power grid enterprise and signs a contract to be a new retail package) and a class B retail user (the contracted power-selling company does not settle with the power grid enterprise or signs a contract to be an old retail package). The package transaction information of the class A retail users is a package which is agreed by the retail users and the power selling companies and comprises a fixed price package and a linkage price package, the fixed price package is a package in which all signed electric quantity is agreed price, and the linkage price package is a package linked with the price of the electric power market; the package transaction information of the class B retail user is the actual power consumption and the electric energy discount price obtained by the electric power selling company in the wholesale market settlement. The financial data is obtained through an interface with a marketing system, and actual electricity consumption data of retail customers are obtained and comprise user basic information (user names, user numbers, metering point numbers and electricity utilization types), electric quantity (normal electric quantity, peak electric quantity, flat electric quantity and valley electric quantity), electricity price codes, work order numbers, business types, electricity consumption charges, basic electricity charges, power dispatching charges, fund sums and arrival electricity charges.

Step five, the retail user settlement execution:

after the settlement basic data is prepared, the settlement service personnel can perform settlement execution operation for retail users. The method comprises the following steps of firstly carrying out settlement algorithm configuration, including the settlement of electric quantity and electric charge of a package contract, the settlement of electric energy and electric charge of excess electric quantity, the settlement of less-used and exempt-from electric charge and the settlement of time-sharing extracted electric charge. The package contract of the class A retail user is the electricity price signed by the platform; the contract electricity quantity of the class B retail users is the actual electricity consumption quantity, and the electricity price is the electric energy and electricity charge discounting price of the contracted retail users. After the algorithm configuration is finished, settlement execution operation can be carried out, the electricity fee settlement is carried out on the retail user, and package electricity fee, super-utilization less electricity fee and marketized to user electricity fee data are obtained after the retail user settlement execution. The electric charge from market to user is the sum of package electric charge, super-consumption less electric charge, transmission and distribution electric charge, basic charge, power transfer electric charge, fund and additional charge.

And after the settlement is executed, filing the settlement data of the retail user for use in subsequent display.

Sixthly, displaying a settlement result of the power consumer:

and electric power settlement service personnel of the electric power transaction mechanism pull the settlement data of the wholesale transaction users and the retail users and combine the settlement data of the wholesale users and the retail users so as to facilitate the settlement service personnel and the power supply enterprises to check the settlement fee information of the electric power market.
