Power systems have been historically expected to operate in a plug-and-play fashion. In the conventional power system, because of its ample inertia and large generators, frequent small changes in the system may not pose any significant challenge. However, moving forward, as (i) the system gets segmented into smaller portions possibly operating autonomously (islanded microgrids) or as a virtual power plant (VPP), or (ii) the resources become more sensitive to changes (low- or no-inertia power electronics based inverters), the need to ensure that the system dynamics are regulated increases to avoid apparatus malfunction, dynamic response challenges, and protection issues. Set point automatic adjustment with correction enabled (SPAACE) is an add-on strategy to improve the performance of an existing controller when the controller itself is gray boxed a common scenario with inverters associated with utility-installed renewable systems.

A/ Prof Ali Mehrizi-Sani discussed the foundational ideas behind SPAACE, its implementation challenges, and applications in several scenarios, including in an experimental test bed. This new strategy allows for simpler and faster implementation of SPAACE in practical systems. Dr Behrooz Bahrani, Senior Lecturer, Electrical and Computer Systems Engineering, Director of the Grid Innovation Hub, hosted the event.
