  • 摘要: 随着“双碳”目标的推进,如何实现多矿区之间的协同优化调度,提升矿区集团整体的低碳性和经济性是急需解决的问题,提出一种双层博弈机制下的矿山综合能源系统多主体协同优化运行方法。首先,基于矿山衍生资源高效利用,构建矿山低碳综合能源运行架构;结合矿山生产生活用能特性,建立以聚合服务商为上层决策者,以能源供给者和用户为下层执行者的矿区级双层博弈模型;其次,根据矿区分布特点,选取具有典型特征的2个矿区提出多矿区协同的运行方法,聚合服务商管理矿山综合能源系统内部整体出力,负责与上级电网和碳市场的能源及碳交易,制定矿区内部能源价格,用户和能源供给者依据价格信息确定并反馈供能和用能策略,调整矿区间能量交互。最后,引入阶梯式碳交易机制,采用自适应差分算法,结合CPLEX求解器对模型进行求解,综合考虑各主体利益,优化得到矿区内部各主体以及矿区间的能源交易价格,实现该模型下矿区效益最大化。以已建成的宁夏某矿区综合能源站实际数据为基础,选取一座新能源发电建设完善的已开发成熟矿山以及一座生产负荷用能需求高、新能源开发占比较小的正在拓建的高浓度瓦斯矿山,设置多矿区综合能源协同运行场景,验证所提模型的有效性。仿真结果表明:所提模型将多个矿山综合能源有效协同,克服了单一调度不能满足多个用能主体需求的局限性,综合提高了多矿区整体的新能源和伴生能源消纳能力。对比矿区之间独立运行的情况,所提方法使得矿区集群整体收益提高48.45%,总碳排放量降低7.71%,提升了集群矿区能源运行的经济性和低碳性。

     

    Abstract: With the advancement of the dual carbon goals, how to achieve coordinated and optimized scheduling among multiple mining areas and enhance the overall low-carbon and economic performance of mining groups has become an urgent issue to be addressed. A multi-agent coordinated optimization operation method for the integrated energy system of mines under a two-level game mechanism is proposed. Firstly, based on the efficient utilization of mine-derived resources, a low-carbon integrated energy operation framework for mines is constructed. Combining the energy consumption characteristics of mine production and life, a two-level game model at the mining area level is established, with the aggregator service provider as the upper-level decision-maker and the energy suppliers and users as the lower-level executors. Secondly, according to the distribution characteristics of mining areas, two mining areas with typical features are selected to propose a multi-mining area coordinated operation method. The aggregator service provider manages the overall output of the integrated energy system within the mines, is responsible for energy and carbon trading with the upper-level power grid and carbon market, and formulates the internal energy prices of the mining areas. Users and energy suppliers determine and feedback the energy supply and consumption strategies based on the price information and adjust the energy interaction between mining areas. Finally, a stepwise carbon trading mechanism is introduced, and the adaptive differential algorithm is adopted, combined with the CPLEX solver to solve the model. Considering the interests of all parties, the energy transaction prices within the mining areas and between mining areas are optimized to achieve the maximization of mining area benefits under this model. Based on the actual data of a comprehensive energy station in a certain mining area in Ningxia, a developed mature mining area with complete new energy power generation facilities and an expanding high-concentration gas mining area with high production load energy demand and a small proportion of new energy development are selected to set up a multi-mining area integrated energy coordinated operation scenario to verify the effectiveness of the proposed model. The simulation results show that the proposed model effectively coordinates multiple mining area integrated energy systems, overcomes the limitation that a single dispatch cannot meet the energy demands of multiple energy users, and comprehensively improves the overall new energy and associated energy consumption capacity of multiple mining areas. Compared with the independent operation of mining areas, the overall revenue of the mining area cluster is increased by 48.45% and the total carbon emissions are reduced by 7.71% with the proposed method, thereby improving the economic and low-carbon performance of energy operation in clustered mining areas.
