论文摘要
在加热和电力系统中，不同的质量流量可以更好地利用加热系统惯性来提高电力系统的灵活性。但是，由于整数变量和现有最佳调度模型中的双线性约束，这具有挑战性。在本文中，我们结合了改进的热管道模型，以消除整数变量的复杂性，而不会妥协准确性。随后，通过提议的修改的广义弯曲器分解方法解决了带有双线性约束的最佳最佳调度模型，该方法将最佳调度模型分解为具有固定质量流量的凸子问题，并搜索最佳质量流量。与现有基准的比较表明，提出的方法可以以出色的计算效率实现较低的运行成本。
In combined heat and power systems, varying mass flow can better make use of the heating system inertia to increase the flexibility of electric power systems. This is challenging, however, due to integer variables and bilinear constraints in existing optimal dispatch models. In this paper, we incorporate an improved heat pipeline model to eliminate complexity from integer variables without compromise on accuracy. Subsequently, the resulting optimal dispatch model with bilinear constraints is solved by the proposed modified Generalized Benders Decomposition method, which decomposes the optimal dispatch model into a convex sub-problem with the fixed mass flow and a simple upper-level problem searching for the optimal mass flow. Comparisons with existing benchmarks show that the proposed method can achieve lower operation costs with outstanding computational efficiency.
