摘要(Abstract)：

目前新能源接入规模不断扩大，传统电力调度方式已难以适应以新能源为主体的电力系统发展需求。为提升电网调峰能力，引入典型高耗能电熔镁负荷作为调节对象，结合电熔镁负荷运行特性建立电熔镁炉功率调节模型，量化其参与系统调峰的可调节潜力；同时在负荷侧配置电池储能系统，构建与火电机组联合优化的双层调度模型。模型上层以风电消纳量最大化为目标，对火电、风电和高耗能电熔镁负荷调节功率进行优化；下层以系统整体运行成本最小为目标，进一步优化火电与储能系统的联合运行功率，形成“电熔镁负荷-储能系统”联合调峰经济调度策略。通过算例仿真验证，该模型在提升新能源消纳能力、降低系统运行成本方面效果显著，具有良好的实际应用前景。
With the continuous expansion of renewable energy integration, conventional power dispatch methods have become inadequate to meet the development needs of power systems dominated by renewable energy. To enhance grid peak-shaving capability, this paper introduces a typical high-energy-consumption fused magnesia load as a regulation resource. Based on the operational characteristics of fused magnesia loads, a power regulation model for fused magnesia furnaces is established to quantify their adjustable potential for participating in system peak shaving. Moreover, a battery energy storage system is configured on the load side to construct a bi-level dispatch model for the coordinated optimization of thermal power units. The upper level of the model aims to maximize wind power consumption by optimizing the regulation power of thermal power, wind power, and the high-energy-consumption fused magnesia load. The lower level minimizes the overall system operating cost by further optimizing the combined operation of thermal power and the energy storage system, forming an economic dispatch strategy for synergistic peak shaving with fused magnesia load and energy storage system. Case study simulations verify that the proposed model significantly improves renewable energy integration capacity and reduces system operating costs, demonstrating strong potential for practical application.
