Joint Optimization of Energy Storage and Energy-intensive Load at Renewable Energy Transmission End

With the rapid development of wind power, the randomness and volatility of wind power have led to increasing pressure on peak regulation and frequency regulation of the power grid, and wind curtailment is serious, especially in the renewable energy transmission end. In this paper, large-scale energy storage and energy-intensive load with adjustable characteristics are taken as important means to promote wind power consumption and participate in the optimal dispatch of the power grid together with conventional thermal power. This work proposes a new model of source-storage-load coordination, which comprehensively considers the impact of source-load coordination on wind power consumption, system operating costs, and energy storage benefits. It optimizes thermal power, energy storage, and energy-intensive load operation to minimize the overall cost of power grid and energy storage. The study's results verify the proposed method's effectiveness in improving the consumption level of wind power and peak cutting.
