Example 2
In a second aspect, the present invention further provides a provincial electric power spot market operation method supporting multi-market coordination, which comprises the following steps according to the sequence of provincial spot market business: information announcement, data declaration, provincial spot shipment clearing (cross-district), regional auxiliary service market clearing and information publishing.
Step 1: information announcement
The national dispatching and branch center compiles a cross-regional inter-provincial junctor plan and calculates the residual available capacity of junctors according to the predicted junctor plan; the provincial dispatching compiles an intra-provincial unit preplanning plan, calculates the maximum electricity buying and selling capacity of each market main body participating in inter-provincial spot goods, and then information such as the residual available capacity of the connecting line and the electricity buying and selling capacity of the market main bodies is subjected to information announcement through a unified power market trading platform;
step 2: data reporting
The market main body declares the 'power-electricity price' data of the spot market participating in provinces through the unified power market trading platform, and the unified power market trading platform is encrypted, stored and directly sent to a production control large-area spot system server;
and step 3: province clear of spot shipment (cross district)
The state dispatching firstly organizes inter-province spot shipment clearing (cross-district), iterates with the whole-network security check to obtain inter-province spot shipment clearing results meeting the power grid security, and issues the inter-province spot shipment clearing results to the branch center and the province dispatching;
and 4, step 4: regional assisted service market clearing
The sub-center adjusts 'power-electricity price' data of the market main body participating in the regional auxiliary service market according to the inter-provincial spot shipment clearing (cross-regional) result, iterates with regional security check to obtain a clearing result of the regional auxiliary service market meeting the power grid security, and issues the clearing result to provincial dispatching;
and 5: information distribution
And the unified power market trading platform obtains the provincial spot shipment clearing (cross-district) result and the regional auxiliary service market clearing result and then issues all clearing data to each market main body according to the authority.
On the whole, the invention discloses an inter-provincial electric power spot market operation method supporting multi-market coordination, which specifically comprises the following steps:
and the market quotation data is sent to the declaration and release data management application by a unified electric power market trading platform of an external system for verification and audit confirmation.
And sending the confirmed market quotation, market boundary and market model data to a market clearing core application function (market clearing in the day ahead, market clearing in the day, and market clearing of an auxiliary service market), finishing market clearing calculation of different periods and different transaction varieties, carrying out basic state trend analysis on formed market clearing results through safety check of a dispatching automation system to ensure physical performability of the results, and sending the market clearing results which finally meet the safety check requirement to the dispatching automation system for execution of a dispatching application function.
Meanwhile, various market operation data can enter market evaluation analysis, market supervision support and market simulation deduction application; the market assessment analysis application develops post-hoc analysis based on market operation data, the market supervision support application develops market supervision based on market operation data, and the simulation deduction application develops post-hoc inversion calculation based on historical examples.
In addition, the market release information is output to systems such as a unified power trading platform after the data management and verification are declared and released.
