“…It passes the bus voltage angle through a derivative computation and a first order filter. It has been shown in (Milano, 2017) that the approach is prone to numerical problems, although it is the standard de-facto approach. An alternative method in (Milano, 2017), is only suitable for domain specific power system tools and not general-purpose ones, e.g.…”

Simulation Led Innovation at Procter & GambleThe required pace of innovation continues to increase in the consumer packaged goods industry. Increasingly historical approaches of development by physical prototypes lead to slow execution, high costs and incremental innovations.By leveraging simulations we can deliver better innovations, faster, at lower costs. Succeeding on this journey requires more than just technical mastery. Changing the way that innovation is done also requires changing how decisions are made and how resources are allocated. It is also necessary to think about the entire lifecycle of the digital assets such as simulation platforms in a manner similar to how we manage our physical assets (e.g. pilot plants). Digital assets required continued funding, maintenance and upgrades to remain viable over time.

“…For simulation, authors in (Milano, 2017) have proposed that the system frequency can be estimated from the center of inertia (COI) concept and a washout filter (WF) on the phase angle of bus voltage. The COI is an artificial modeling construct and in practice it cannot be used (Diez-Marotoet al, 2001).…”

“…In this section, fast voltage boosters for GF-VSCs are proposed to improve transient stability. The proposed controllers are based on reactive-power/voltage control in the VSCs and they were inspired by the excitation boosters for synchronous machines proposed in [28][29][30] to improve transient stability in multi-machine systems.…”

“…In other words, some VSCs will have to be slowed down while others will have to be accelerated. This is, again, analogous to the case of a multi-machine system with conventional synchronous generators, where the use of the speed of the centre of inertia (COI) has proved to be useful [28][29][30].…”

“…Furthermore, the use of reactive-power/voltage control strategies to improve transient stability have been successfully applied in traditional synchronous generators (i.e. excitation boosters) [25][26][27][28][29][30], in shunt FACTS devices [31] and in high voltage direct current systems based on voltage source converters (VSC-HVDC) [32,33]. The good results obtained there, has motivated this research.…”

Grid-forming voltage source converter (GF-VSC) has been identified as the key technology for the operation of future converter-dominated power systems. Among many other issues, transient stability of this type of power systems remains an open topic of research because it is still a key limiting factor for stressed power systems. Previous studies have proposed control strategies for GF-VSC to improve transient stability of this type of systems by suitable current-limitation algorithms and/or control of active-power injections. As an alternative, this paper proposes two fast voltage boosters to improve transient stability of power systems with 100 % of GF-VSC-based generation with virtual synchronous machine (VSM). One control strategy uses local measurements, whereas the other one uses global measurements of the frequency of the centre of inertia (COI). Both strategies improve transient stability of this type of systems significantly. The advantage of using fast voltage boosters for this purpose is that the set points linked to frequency/active-power injection (i.e set points linked to the primary energy source of the VSCs) will not be modified. Furthermore, strategies such as current-limitation, active-power control and fast voltage controllers for transient stability improvement are compatible and complementary.
