论文摘要
在过去的二十年中积累的巨大技术潜力将使能够完全改变电力系统的运行原理。随之而来的技术演变不仅影响电力市场的结构，而且还影响传输系统运营商（TSO）与配电系统运营商（DSOS）之间的相互作用。需要新的实用解决方案来改善国家，TSO和地方级别DSO的电网运营商之间的协调。在本文中，我们定义了TSO和DSO之间协调的灵活性范围。通过这样做，我们通过数学编程和电力系统原理提出了一种基于Epsilon受限方法的算法。我们评估和比较不同的经典最佳功率流程（AC-OPF，Distflow，Distflow-SOCP和LindistFlow），以构建灵活的TSO-DSO柔性域。本文中提出的方法在IEEE 33-BUS测试径向分布系统中进行了分析。我们表明，对于这个特殊的问题，尽管凸出放松方法的学术界流行，但驱动器SOCP的准确性最差。
The enormous technological potential accumulated over the past two decades would make it possible to change the operating principles of power systems entirely. The consequent technological evolution is not only affecting the structure of the electricity markets, but also the interactions between Transmission System Operators (TSOs) and Distribution System Operators (DSOs). New practical solutions are needed to improve the coordination between the grid operators at the national, TSOs, and local level, DSOs. In this paper, we define the flexibility range of coordination between TSOs and DSOs. By doing so, we propose an algorithm based on epsilon-constrained methods by means of mathematical programming and power systems principles. We evaluate and compare different classical optimal power flow formulations (AC-OPF, DistFlow, DistFlow-SOCP, and LinDistFlow) for building the flexible TSO-DSO flexible domain. The presented approaches in this paper are analyzed in an IEEE 33-bus test radial distribution system. We show that for this particular problem, the DistFlow-SOCP has the worst accuracy, despite the popularity among the academic community of convex relaxation approaches.
