Abstract

The invention discloses a clearing method of an electric power market. At first, a security constraint unit combination model is established according to the data of a power system, a unit start-stopplan is obtained by solving the security constraint unit combination model, and, according to the output and price application of the day-ahead start-up units in the FM market in the unit start-stop plan, after clearing, the pre-clearing result of the FM auxiliary market is calculated, so that the clearing of FM auxiliary market is realized. The upper and lower output limits of the pre-clearing unit are corrected according to the pre-clearing result, and, based on the modified upper and lower output limits, a security constraint economic dispatching model is established. The day-ahead unit output plan is obtained by solving the model, which realizes the day-ahead power market clearing, and the day-ahead power generation plan which is closer to reality is obtained by reserving the system FMunit capacity, so as to prevent the mismatch between the clearing result and the actual demand of the system and ensure the executability of the clearing result of the day-ahead dispatching plan. Theinvention also discloses a clearing device and clearing equipment of an electric power market, which have the beneficial effects mentioned above.

Description

technical field [0001] The invention relates to the field of electric power market, in particular to a clearing method, clearing device and clearing equipment of the electric power market. Background technique [0002] In the electricity market environment, the traditional power generation plan is transformed into the calculation of electricity transactions between buyers and sellers, that is, the electricity market is cleared. In addition to the electric energy market, the power market also has a frequency regulation auxiliary service market to ensure the safe and stable operation of the power grid. In order to ensure the stable start of the electricity spot market and simplify the market clearing mechanism, the initial stage of the construction of the electricity spot market will adopt the decoupled operation method of the electric energy market and the auxiliary service market, that is, the electric energy market and the frequency modulation auxiliary service will be clea...
