| description | In response to the challenge of new energy consumption in the Gobi Desert and barren land areas, this paper introduces a low-carbon dispatch strategy for power systems that is based on hierarchical and incremental optimization. The strategy takes into account the effects of demand response, electrochemical energy storage stations, new energy units, and carbon trading mechanisms, with the goal of enhancing the grid’s capacity to consume new energy in these regions while also minimizing operational costs and carbon emissions. In particular, the upper-level model maximizes the grid’s potential for new energy consumption by refining the covariance between load forecasts and wind and solar predictions. Concurrently, the lower-level model harmonizes various peak-shaving resources and incorporates a tiered carbon trading cost, thus establishing a multi-objective “source-grid-load-storage” collaborative low-carbon scheduling framework. Simulation tests indicate that the proposed framework effectively diminishes wind and solar curtailment rates, bolsters the grid’s consumption capability for wind and solar power in the Gobi Desert and barren regions, and decreases both operational expenses and carbon outputs. Moreover, this study delves into the influence of carbon pricing on metrics such as wind and solar consumption rates, overall system costs, daily carbon emissions, and daily thermal power generation. It has been observed that as the price of carbon trading escalates, both the consumption rate of wind and solar power and the total system costs gradually rise, whereas daily thermal power production and carbon emissions steadily decline. This insight furnishes theoretical backing and practical direction for the integration of carbon trading schemes into power systems with substantial new energy components. |
