一种计及能量枢纽不同运行模式的综合能源系统混合能量流求解方法

A Multi-energy Flow Calculation Method for Integrated Energy System Considering Different Operation Modes of Energy Hub

  • 摘要: 综合能源系统的混合能量流求解是后续能量综合管理与调控的基础环节。为避免传统统一求解能量流时可能存在的模型维度高、收敛性差等问题,同时充分考虑能量枢纽(energy hub,EH)在不同运行模式下对系统能流分布的影响,提出了一种计及EH不同运行模式的综合能源系统混合能量流求解方法:基于EH建模以及建立电、气、热各能源子系统的能流独立求解模型,划分典型运行模式,利用EH单元输入输出的钳制约束对各能源子系统的能流独立计算结果进行迭代校正,实现EH在不同运行模式下的能流流程化求解。算例结果表明,此算例适用于不同运行模式的混合能量流计算,且具有较好的收敛性与合理性。

     

    Abstract: Multi-energy flow calculation of integrated energy system is the basis and premise of energy management and regulation. To solve the problems of high complexity and low convergence efficiency during the energy flow calculation process with traditional unified calculation method, a multi-energy flow calculation method for integrated energy system considering different operation modes of energy hub was proposed. Based on the energy hub modeling, the independent calculation model of the hybrid energy flow was established and the typical operation modes were analyzed. Relaying on the clamp constraints of EH input and output, the independent calculation results of each energy subsystem can be corrected iteratively, so as to realize the standardization solution flow under different operation modes. Testing case results show that operation modes of energy hub make great influence on the multi-energy flow distribution, besides, the calculation method, which takes different operation modes of energy hub into account, can achieve good convergence efficiency and is of certain rationality.
