It was recently observed that a significant gap exists between the costs of Transmission Network Expansion Planning (TNEP) solutions produced by the DC power flow approximation and AC power flow heuristics. This paper confirms the existence of that gap and shows that DC-based TNEP solutions exhibit significant constraint violations when converted into AC power flows. The paper then demonstrates how to bridge this gap with the LPAC power flow model, a linear-programming approximation of the...[Show more]
