The Guest Editors are inviting submissions to a Special Issue of\u00a0Energies\u00a0on the upgrading and uprating of transmission and subtransmission systems.\u00a0Existing HV and EHV AC networks are being affected by the ongoing change in generation and load in different ways. The increasing reliance on distributed generation and renewable energy sources (RES) leads to a drastic alteration and overall reduction of power flows at the transmission (EHV) level, possibly creating new bottlenecks, whereas HV subtransmission networks in high-RES penetration are becoming \u201cactive\u201d, collecting RES generation and becoming increasingly stressed.\u00a0The utilities\u2019 response to this paradigm shift must take into account the difficulty of reinforcing the network. This Special Issue will deal with techniques for operating and upgrading AC subtransmission systems.\u00a0Topics of interest for publication include, but are not limited to:\u00a0Planning criteria for active subtransmission networks;\u00a0Partial or total undergrounding of HV subtransmission networks;\u00a0\u201cMixed\u201d overhead-cable AC lines;\u00a0Overhead line reconductoring\/uprating;\u00a0Conventional or controllable series and shunt compensation;\u00a0Operation and control of active subtransmission networks;\u00a0Unscheduled power flows;\u00a0Overvoltages, neutral grounding, and protective issues for active subtransmission networks;\u00a0Distributed temperature sensing\/dynamic line rating.
