摘要
为促进新能源消纳,提高储能大规模分散接入条件下区域多能源系统运行的经济性和灵活性,充分发挥分布式储能协调优势,文章提出一种面向新能源消纳的区域多能源系统网格化储能协调优化模型。首先,研究计及电力热力能源网络和分布式储电储热的区域多能源系统模型;然后,考虑多能源网络中能量传输特性,以储能动态调节过程中储能节点调节容量和储能节点传输容量作为网格化指标,提出区域多能源系统网格化储能划分方法;最后,以电网购电成本、分布式储能运行成本及弃新能源成本最小化为目标,构建区域多能源系统网格化储能协调优化模型。通过仿真算例验证了模型的有效性。
In order to promote the absorption of new energy and improve the economics and flexibility of the operation of regional multi-energy systems under the condition of large-scale decentralized access to energy storage,a coordinated optimization model of grid-based energy storage in a regional multi energy system considering renewable energy accommodation is established.First,a regional multi energy system model that takes into account the electric thermal energy network and distributed energy storage is studied.Secondly,based on the energy storage node adjustment capacity and node transmission capacity indicators in the process of dynamic energy storage regulation,a partition method of energy storage for regional multi energy systems was proposed,taking into account the energy transmission characteristics of multi energy networks.Finally,the coordinated optimization model of grid-based energy storage in a regional multi energy system was established.The validity of this model is verified in simulation examples.
