Beschreibung: As a greater number of nuclear, coal, and gas based power plants are retired in favour of power electronic-interfaced cleaner renewable sources, the apprehensions over its impact on the operation of power grids too has steadily increased. A widely employed remedy is the emulation of inertia (mimicking the operation of synchronous machines) via storage elements. Recent research [1] suggests that “placement” of this inertia across the grid greatly characterises the system performance (H2 norm based performance metrics [2]). The resulting optimisation problem to determine the locally optimal allocations is however non-convex and involves non-trivial gradient computation techniques. The goal of this student project is to examine the effects of dynamic load models, and realistic state-space models of synchronous machines, on inertia “placement” and compare it’s performance vis-à-vis the linearised model with static loads in [1]. The main steps of the project are as follows:
