Abstract

A day-ahead low-carbon dispatching strategy of power system for new energy consumption in desert, Gobi and desertification land is proposed to address the issues of poor consumption and economic efficiency of new energy units. Considering the complexity of the system structure, a model layered optimization scheme is adopted. The upper level model aims to optimize the power load curve and release the potential of new energy consumption in the power grid by minimizing the covariance between the optimized load and the total wind forecast value. By coordinating the optimized load of wind turbines, photovoltaic units, energy storage power stations, thermal power units and the upper model, the lower model introduces the carbon transaction cost of the ladder into the objective function, and establishes the multi-objective "source-grid-storage-load" collaborative low-carbon scheduling model, aiming to improve the economy of system operation, reduce the carbon emissions of the system, and improve the absorption capacity of new energy. Finally, simulation tests are carried out on the improved IEEE 30-node system, and the results verify the effectiveness of the model.
