On the Implementation of OPF-Based Setpoints for Active Distribution Networks

In the context of active distribution networks, AC Optimal Power Flow (OPF) has shown great potential to calculate setpoints for controllable devices. Although considerable literature exists, temporal aspects that may affect actual execution these are rarely investigated. Due diverse operating characteristics devices (i.e., delays, ramp rates and deadbands), when executed by multiple without adequate considerations, resulting outcome can differ drastically from what is expected; leading violations network constraints excessive control actions. Therefore, this work proposes a series necessary adaptations within controllers existing as well in OPF formulation cater diversity characteristics, ensuring calculated adequately implemented This involves direct conventional enforcing new ramping behavior inverter-interfaced Furthermore, linear, mixed-integer proposed handle discrete improve scalability large networks. Co-simulation results (using U.K. test with objective maximizing renewable energy production considering 1s time-step) demonstrate that, catering devices, expected OPF-based be achieved.
