中文摘要：光伏、储能电池、燃煤热电联产机组组成的综合能源系统,其电力热力系统间孤立运营,为分析其热力电力系统间的信息交互与经济协调调度的关系,依据J.F.Benders混合变量目标分解法对热电联产光储热力电力系统的物理模型按照热力主系统和电力子系统进行分解,通过目标函数和系统边界条件分析子目标之间的信息交互情况,得出光电消纳储存与热电联产协调调度运行的数学模型,并对保护信息加以隔离重定向,以Gurobi求解器迭代计算混合整数规划多维变量问题.基于综合能源系统案例分析了电力热力不同负荷需求下的3种运行工况,发现热力电力运营系统间经济效益协同互补,且信息交互扩大了光电的消纳空间,系统净负荷平均降低了 13.63%,交互功率损失每年减少了 948.07 万元,能源利用效率提高了 4.48百分点,可见本模型可以服务于综合能源系统的经济协调调度优化和提高能效.

外文标题：Operation optimization for thermal and electrical systems composed of cogeneration,photovoltaic power and power storage based on mixed variable objective decomposition model

外文摘要：For the integrated energy system composed of photovoltaic power generation,energy storage battery storage and discharge,and coal-fired heating boiler and cogeneration,the power and heat power systems operate in isolation.To analyze the relationship between the information interaction and economic coordination and dispatch of the integrated energy system,by using the J.F.Benders mixed variable target decomposition method,the physical model of the cogeneration photovoltaic storage thermal power system is decomposed according to the main thermal system and the power subsystem.The information interaction between the sub-objectives is analyzed by the objective function and the system boundary conditions,and the mathematical model of the coordinated scheduling operation of photoelectric consumption and storage and cogeneration is obtained.The protection information is isolated and redirected,and the multi-dimensional variable problem of mixed integer programming is iteratively calculated by Gurobi solver.Based on the case of the integrated energy system,three operating conditions under different load requirements of power and heat are analyzed,and it is found that,the economic benefits of the thermal power operation system are synergistic and complementary,and the information interaction expands the space for photovoltaic consumption.The net load of the system reduces by 13.63%on average,the interactive power loss decreases by 9.480 7 million yuan/year,and the energy utilization efficiency rises by 4.48 percentage points,which shows that this model can serve the economic coordination and scheduling optimization and energy efficiency improvement of the integrated energy system.
