摘　　要：针对现有综合能源系统规划研究中缺乏科学有效的站址优化方法,且在能源站供能范围划分过程中未能考虑负荷特性的问题,提出一种考虑负荷特性互补的能源站网协同规划方法。首先,基于综合能源系统站网规划间的相互作用分析,提出能源站布点、供能范围划分及管网布局交替优化思路;其次,基于能源站供能半径范围,提出新建能源站数量确定方法,并结合蜂窝网络拓扑特征,提出初始站址确定方法;进而,考虑负荷特性互补,提出了综合能源站供能范围划分评价指标及划分方法;再次,针对道路上的管网布局问题,提出基于Kruskal算法的管网优化方法,结合线性优化模型实现负荷与道路管网接入方向的优化;继而,提出了负荷等效能矩计算方法及基于等效能矩的站址优化方法;最后,通过算例验证所提方法的合理性和有效性。Aiming at the lack of effective site optimization method of integrated energy system planning and failing to consider the load characteristics in energy supply area division process, an coordinated optimal method for energy station and pipe network planning considering complementary load characteristics was proposed. Firstly, based on the interaction effect of station and network planning, an alternated optimal method for station sitting, energy supply area division and pipe network layout was proposed. Then based on the energy supply radius of energy station, the method of determining the number of new energy stations was proposed. Secondly, based on the topological characteristics of cellular networks, the initial site determination method was presented. Thirdly, considering the load characteristics, the evaluation index and division method of the integrated energy stations energy supply area division were proposed. After that, aiming at the problem of pipe network layout on the road, a pipe network optimization method based on Kruskal algorithm is proposed. Combined with the linear optimization model, the load and road pipe network access direction were optimized. Then, the calculation method of load "equivalent energy distance" and the site optimization method based on "equivalent energy distance" were proposed. Finally, the efficiency and practicability of the method are demonstrated on a practical system.
