| 摘要: |
| 为了提升综合能源系统的能源利用效率，基于能量梯级利用原理，对能源站选址、设备选型定容和能源网络布局进行协同规划；同时考虑负荷的能源品位互补特性，建立了一种考虑能量梯级利用的园区综合能源系统站网双层规划模型。上层模型以考虑能源站和能源网络投资成本最小为目标，建立能源站网协同投资模型；下层模型考虑负荷间的能源品位互补，以兼顾?效率的运行成本最小的目标，建立能源站的运行模型。在此基础上，基于最短路径理论的枚举法，采用CPLEX求解器进行模型求解。选取了北方某园区综合能源系统对所提方法进行了仿真验证，结果表明所提方法实现了负荷间的能源品位互补，解决了传统规划时能源需求和能源供应品位不匹配的问题。 |

| Abstract: |
| In order to improve the energy utilization efficiency of integrated energy system, based on the principle of energy cascade utilization, the site selection of energy stations, equipment selection and capacity determination, and energy network layout are coordinated. At the same time, considering the complementary characteristics of energy grade of load, a bi-level planning model of station and network of park integrated energy system is established. The upper-level model aims to minimize the investment cost of energy stations and energy networks and establishes a collaborative investment model of energy stations and networks. The lower-level model considers the energy grade complementation among loads, and establishes the operation model of energy station with the goal of minimizing the operation cost while taking the exergy efficiency into account. On this basis, based on the enumeration method of shortest path theory, CPLEX solver is used to solve the model. A north park integrated energy system is selected to verify the proposed method by simulation. The results show that the proposed method realizes the energy grade complementation among loads and solves the problem of mismatch between energy demand and energy supply grade in traditional planning. |
