【摘要】：近年来含分布式能源的热电联供系统在区域能源系统中得到了广泛应用,而传统故障分析仅针对供电系统进行决策,缺乏对综合能源系统的整体考虑。文章在热电联供能源系统供电中断情况下,研究综合能源系统供能恢复问题。引入换热站模型和高耗电、高产热的大型耗能用户模型描述热电耦合关系,对热-电系统间的能量生产、分配、转换以及不同等级负荷的供能恢复过程进行建模,考虑热惯性影响,利用供热量在空间和时间的弹性,构建热电联供系统负荷恢复策略模型,并用CPLEX求解器求解,得到故障后负荷综合损失最小的方案。利用某热电联供系统算例验证所提方法的有效性。
[Abstract]:In recent years, heat and power cogeneration systems with distributed energy have been widely used in regional energy systems, but traditional fault analysis only makes decisions for power supply systems. In this paper, the problem of energy recovery of integrated energy system is studied under the condition of the power supply interruption of the combined heat and power supply system, and the heat transfer station model and high power consumption are introduced. The large energy consumption user model with high thermal yield describes the thermoelectric coupling relationship and models the energy production, distribution, conversion and energy supply recovery process between thermoelectric systems, taking into account the influence of thermal inertia. Based on the elasticity of heat supply in space and time, the load recovery strategy model of heat and power supply system is constructed and solved by CPLEX solver. The scheme of minimum comprehensive loss after failure is obtained, and the effectiveness of the proposed method is verified by a heat and power system example.
