Network partition based on critical branches for large-scale transmission expansion planning

摘要: The size and complexity of large power systems, such as the European one, often make them unmanageable for purposes Transmission Expansion Planning (TEP). Therefore, network reduction methods are necessary to condense their key features into a workable model, which should approximate behavior nodal system accurately possible. We define critical branches transmission lines that particularly relevant TEP because of, instance, frequent congestions or special nature cases HVDC (High-Voltage Direct Current) PSTs (Phase-Shifting Transformers). It would be desirable preserve these while simplifying remaining grid. propose heuristic algorithm creates an initial partition is later refined by clustering nodes based on composite distance measure. proposed technique has been applied real case study French Spanish systems.
