Embodiment 1

[0048] figure 1 It is a flow chart of a transaction method for the transfer and transaction of power generation rights in solar thermal power plants to promote the consumption of new energy. Such as figure 1 As shown, the process flow of the day-ahead power generation right transfer transaction method for photothermal power plants that promotes new energy consumption provided by the present invention includes:

[0049] S1: Obtain the information on the forecasted output of new energy in the day-ahead, and there is a demand for the transfer of power generation rights in the day-ahead;

[0050] S2: Organize the transfer transaction of solar thermal power generation rights during the limited period of power generation of new energy stations;

[0051] S3: Organize the transfer of solar thermal power generation rights during the surplus period of new energy stations;

[0052] S4: Form the day-ahead power generation rights transfer transaction results of new energy stations and sol...

Embodiment 2

[0094] In a certain regional power grid, there are two 330kV substations, two wind farms, one photovoltaic power station, and one solar-thermal power station. Among them, the total installed capacity of the wind farm and photovoltaic power station is 300MW, and the installed capacity of the solar-thermal power station is 100MW. . The contract on-grid electricity price of wind farm 1 is 325 yuan / MWh, and the average power generation cost is 120 yuan / MWh; the contract on-grid electricity price of wind farm 2 is 335 yuan / MWh, and the average power generation cost is 130 yuan / MWh; the benchmark on-grid electricity price of photovoltaic power generation The average power generation cost is 140 yuan / MWh, the contract electricity price for solar thermal power generation is 447.5 yuan / MWh, and the average power generation cost is 210 yuan / MWh.

[0095] According to the transaction contract reached in advance, the planned output data (in MW) of wind farms, photovoltaic power stations a...

Abstract

The invention belongs to the field of market transaction after large-scale wind power integration, and particularly relates to a photo-thermal power station day-ahead power generation right transfer transaction method for promoting new energy consumption, which comprises the following steps: obtaining new energy day-ahead predicted output information and having a day-ahead power generation right transfer demand; organizing a photo-thermal power generation right transfer transaction in a power generation limited period of the new energy station; organizing a photo-thermal power generation rightacceptance transaction in a power generation surplus period of the new energy station; forming a day-ahead power generation right transfer transaction result of the new energy station and the photo-thermal power station, and calculating the expected income of each transaction subject; and correcting the day-ahead power generation plan according to the power generation right transfer transaction result, and issuing and executing the plan. The method is used for solving the problem of deviation between wind power day-ahead power prediction and contract planned output, and provides reference forguaranteeing priority power generation of new energy and expected income of a photo-thermal power station.

Description

technical field [0001] The invention belongs to the field of market transactions after large-scale wind power is connected to the grid, and in particular relates to a transaction method for transfer of power generation rights of photothermal power stations that promotes the consumption of new energy. Background technique [0002] In recent years, with the rapid growth of new energy installed capacity, the problem of difficulty in grid connection and consumption caused by forecast deviation is still prominent. [0003] At present, domestic and foreign scholars have carried out a lot of research on the corresponding control methods and strategies for the large-scale integration of new energy into the power grid. A series of solutions to ensure the consumption level of new energy, such as the joint dispatch of new energy and conventional thermal power, high energy-consuming enterprises and the optimization of source and load with the participation of distributed electric vehicl...
