Problems solved by technology

[0004] The invention discloses a market clearing method in which demand-side market entities and generator sets bid on the same platform, which helps to solve the problems of large peak-to-valley difference and severe load fluctuation of the power grid, and can realize separate pricing of the demand side and the generator set, Without affecting the interests of market players, the initiative of demand-side players in the market and enthusiasm for participating in the market can be improved as much as possible, and it can avoid demand response bidding behavior from affecting market prices, which is conducive to stabilizing the normal operation order of the spot market

Embodiment Construction

[0058] In order to illustrate the technical solution of the present invention more clearly, the following in conjunction with the attached figure 2 Specific embodiments of the present invention will be described in detail.

[0059] Such as Figure 1-3 As shown, the present invention discloses a market clearing method in which demand-side market entities and generator sets bid on the same platform, which can realize separate pricing on the demand side and generator sets, and can achieve as much as possible without affecting the interests of market entities. Improve the initiative of demand-side entities in the market and the enthusiasm to participate in the market; the specific implementation steps are as follows:

[0060] A. Publish requirements stage. One day before the operation day, when the system operator predicts that there may be a power supply gap in the grid, it decides to start demand response, and releases demand-side response information to demand-side market pl...

Abstract

The invention discloses a market clearing method in which demand-side market entities and generator sets bid on the same platform. The specific clearing procedure includes: Step 1: Solve the security-constrained unit combination problem considering demand-side quotations; Step 2: Solve considerations The security-constrained economic scheduling problem of demand-side quotation; step 3: calculate the node electricity price considering the demand-side quotation; step 4: perform security check, if the security check passes, then execute step 6; if the security check fails, execute Step 5; Step 5: Modify the system operating boundary conditions and unit operating constraints, and go to Step 1; Step 6: Correct the load forecast curve of the corresponding bus node based on the bid winning result of the demand side and clear the power generation side for the second time to obtain The unit combination problem that only considers the generator unit quotation; Step 7: Solve the economic dispatch problem that only considers the generator unit quotation; Step 8: Calculate the node electricity price that only considers the generator unit quotation.

Description

technical field [0001] The invention relates to the field of electric power spot market mechanism, in particular to a market clearing method in which demand-side market entities and generator sets bid on the same platform. Background technique [0002] Power users have considerable adjustment potential and need effective market mechanisms to guide their utilization. With the continuous improvement of the power spot market mechanism and the gradual liberalization of the user-side market, it has become the development trend of the power market to replace the traditional power demand-side management with demand-side response transactions, and the integration of demand-side resources into spot market transactions has far-reaching development. prospect. At present, my country's spot market adopts the participation method of quoting quantity but not quoting on the demand side at this stage, and guides the elasticity of user demand through clearing prices in the day-ahead market. ...
