The application layer has an evaluation analysis function and can analyze various transaction scenes and results in the service layer from the aspects of market operation, market benefits, scheduling operation and the like.
When the system is used for the first time, a system manager needs to input or import basic information of the thermodynamic users in batches under a user information management page in a data management function in advance, wherein the basic information comprises company names, user types, registered addresses, company legal persons, company properties, established dates, contact persons and contact telephones. Meanwhile, under a permission management page in a system management function, a system manager grants a system use permission for the input thermal users and allocates a system login account and a password.
The thermodynamic user completes the first login of the system according to the login account and the password, and at the moment, the thermodynamic user can only check personal basic information in user information management. When logging in the system for the first time, a thermal user needs to complete the entry of the rest data under the data management function module by himself, and the method comprises the following steps: information such as the name, the number, the area, the power consumption rate and the like of the station in the station management; the equipment parameters include equipment type, rated capacity, highest technical output, lowest technical output, equipment efficiency, auxiliary equipment power consumption, minimum running time, minimum downtime, normal rising rate and normal falling rate. The physical information of the data only needs to be input once, and then maintenance operations such as addition, deletion, modification and the like are carried out according to the needs of users. Equipment operation plan, equipment maintenance plan, spot market declaration data and peak shaving market declaration data in declaration data management need to be declared within a specified time before each thermal user participates in market transaction.
The heat power user checks the direct electricity purchase trade contract simultaneously: the direct electricity purchase transaction is the direct transaction work of the power consumer and the power generation enterprise implemented under the rules of direct transaction implementation of the power consumer and the power generation enterprise in 2021 of A province. The heat power user of the system is also the power user, and the external system participates in the direct electricity purchase transaction in advance according to the relevant rules. The system acquires annual transaction contract information of a thermal user, including voltage grade, repayment capacity and transaction electric quantity data of each month, by data interaction with the external system, and summarizes the annual transaction contract information in a form of a table.
After the heat power user logs in the system, the direct electricity purchase transaction page in the transaction management module is opened, and then the personal annual transaction contract information can be checked.
After logging in the system, a system manager opens a direct electricity purchase transaction page in the transaction management module, and can check all the thermal user lists and annual transaction contract information participating in direct electricity purchase transaction.
The heat users participate in peak shaving market trading: and the heat user logs in the system to perform peak-shaving market transaction declaration before the transaction declaration time is expired. Since the thermal user has already performed the plant management and the data entry in the device parameter page at the initial login of the system, the data does not need to be entered again. Under the reporting data management function, a heating power user needs to fill in an equipment operation plan, an equipment maintenance plan and peak-shaving market reporting data in sequence according to the condition of the same transaction day. In the data declaration page, a thermal user can select one key to import historical declaration data and then modify the historical declaration data; new declaration data can be directly input; and clicking a save button to finish the data declaration operation. Particularly, if the thermal user does not declare an equipment operation plan and an equipment maintenance plan, the system automatically declares according to a default value, namely the equipment operation plan is automatically generated by a peak shaving market model, and the equipment maintenance plan declares according to no maintenance; and the peak shaving market declaration data are necessary filling declaration data for participating in peak shaving market trading, and if the heat power user does not complete declaration before the declaration trading time, the system defaults that the user does not participate in the peak shaving market trading. The peak regulation market declaration data meets the requirements of the 'A power-saving auxiliary service market operation rule', and comprises equipment peak regulation declaration and a peak regulation power utilization curve. The equipment peak regulation declaration page comprises a peak regulation price, a minimum peak regulation market, a peak regulation clearing lower limit and a peak regulation time period setting. The peak shaving electricity utilization curve page comprises basic electricity utilization, reference electricity utilization and peak shaving electricity utilization, and electricity utilization data of 96 time periods (one time period every 15 minutes) are respectively: the basic power utilization is a power load average value of normal production of a peak shaving auxiliary service market which is not participated by a user 5 days before the declaration date, and the power load average value is automatically generated by the system according to historical load data; the reference power utilization is a planned power utilization curve that the user does not participate in peak shaving, and the power utilization is reported by the heat power user independently or can be reported by a system agent; the peak-shaving power consumption is a planned power consumption curve of a peak-shaving auxiliary service market participated by a user, and the planned power consumption curve is automatically declared by a heating power user or can be declared by a system agent.
During peak shaving transaction declaration, a system manager can check the declaration state of the whole system through a peak shaving flow monitoring page under a transaction management function, wherein the declaration state comprises the number of declared peak shaving users, the highest declaration price in each period, the lowest declaration price, the unified declaration price in the system and the peak shaving capacity curve in each period.
