The topic of providing controllable reactive power (CQ) to the next-higher voltage level based on controlling distributed energy resources (DER) has recently received increasing attention. From a theoretical perspective, the use case of deferring or avoiding Extra High Voltage (EHV) investment in compensating equipment by the ancillary service 'provision of controllable reactive power from High Voltage (HV) to EHV' would seem within future reach in certain cases. Despite the comparatively higher losses related to HV DER controllable reactive power provision, the use case is shown to be potentially economically attractive under certain circumstances. However, a considerable number of practical barriers exist that are presented in a systematic way based on a decision flowchart. Simulation results are based on a close-to-real German EHV/HV system and measured data. They highlight the benefit resulting from optimized dispatch of both EHV/HV tap changer and HV DER providing CQ. |
