Photo-thermal power station and wind power system considering carbon transaction, and low-carbon dispatching method and system

Abstract

The invention relates to a photo-thermal power station and wind power system considering carbon transaction, and a low-carbon economic dispatching method and system based on the system. Through the combined operation of wind power, thermal power and photo-thermal power, the photo-thermal power station shares the standby capacity borne by a thermal power unit, the carbon emission can be reduced, and the wind power consumption is promoted; the electricity-heat conversion link, the photo-thermal power station and the thermal power generating unit jointly provide spinning reserve for the system, the output of a traditional thermal power generating unit can be effectively reduced, then the carbon emission is reduced, the wind power consumption level is effectively improved, and meanwhile the economical efficiency of operation is guaranteed. In the low-carbon economic dispatching method and system, the optimal comprehensive cost of a power system is taken as an objective function, and a low-carbon dispatching model is constructed in combination with constraint conditions of all unit elements; and a low-carbon dispatching scheme is obtained based on the low-carbon dispatching model, so that low-carbon operation of the power system is facilitated.

Description

Technical field[0001]The present invention relates to the field of low-carbon scheduling techniques of power systems, and more particularly to a photothermal power station and a wind power system for carbon transactions, a low-carbon scheduling method and system of a light power plant and a wind power system based on a carbon transaction.Background technique[0002]In recent years, environmental pollution caused by carbon emissions has become increasingly serious, and low-carbon development has become a global consensus. In the face of severe ecological protection situations, my country has proposed a strategic goal of 2030 carbon emissions by 2030 to 60% to 65% in 2030.[0003]The implementation of low carbonization in power systems can be summarized as two aspects: technical aspects, such as new energy technology such as wind power and photothermal heat; in terms of policy, introduction of carbon transactions, improve market mechanisms. Coordination with two side coordination and can ...

Problems solved by technology

[0004] Existing studies have analyzed the role of low-carbon technologies such as photothermal and carbon trading mechanisms in curbing carbon emissions and promoting new energy consumption, which has certain theoretical and practical value, but there are still problems that can be further studied and discussed: 1) From the inside of the solar thermal power station, there is still insufficient analysis on how the joint operation of the electrothermal conversion link and the heat storage device affects the carbon emissions, the amount of abandoned air and the operating cost; The effect of the conversion link and the thermal power station sharing the rotating reserve of the thermal power unit to reduce carbon emissions and the impact on the overall cost of the system need further study; 3) There are few studies considering the combined operation of wind power, thermal power and solar thermal Low-carbon policies to further reduce the carbon emissions of the power system and improve the consumption level of wind power and solar heat
