论文摘要
线性编程用作优化能源供应系统中单元承诺或功率流的标准工具。但是,对于热供应系统,它面临着一个相关的限制:对于它们而言,能量产量取决于输出温度,因此必须同时优化两个量,并且结果问题是二次的。作为解决方案,我们描述了一种具有离散温度水平的方法。本文介绍了各种技术的数学模型,并在案例研究中展示了其潜力,该案例研究的重点是综合住宅热量和电力供应。结果表明,该技术会产生合理的结果,包括选择操作温度。
Linear programming is used as a standard tool for optimising unit commitment or power flows in energy supply systems. For heat supply systems, however, it faces a relevant limitation: For them, energy yield depends on the output temperature, thus both quantities would have to be optimised simultaneously and the resulting problem is quadratic. As a solution, we describe a method working with discrete temperature levels. This paper presents mathematical models of various technologies and displays their potential in a case study focused on integrated residential heat and electricity supply. It is shown that the technique yields reasonable results including the choice of operational temperatures.
