“…Therefore, the frequency signal is integrated from the external source rather than from the load bus, which is discussed in detail in section I. This way, a new SDLExpo is able to regulate available reserve according to f avg to solve the WA-FF during either under/over or both frequency events as in (3).…”

<p>Low-inertia power systems, including frequently incorporating inverter-based smart appliances (IbSA), introduce challenges concerning voltage and frequency responses, resulting in increased localized frequency deviations and wide-area frequency fluctuations (WA-FF). These disturbances can trigger cascading effects, potentially leading to `blackouts' if not promptly managed. Within IbSA, certain critical load categories can promptly control voltage and frequency signals from external measurements, enabling them to adapt to variations in active power around nominal ratings. In this study, these loads are referred to as `smart exponential dynamic loads' (SDLExpo). The power reserves of SDLExpo are quantified and aggregated at power stations operating at the 400/230/138kV transmission level, collectively forming a wide-area active power reserve (WA-APR). SDLExpo integrates with the demand response-aggregated frequency service provider (DR-AFSP) regulation market concept, leveraging cost-effective communication and measurement signals. Finally, a distributed control frequency signal-based dynamic load (DCFSbDL) technique is proposed for real-time regulation of WA-APR in a coordinated manner following WA-FF events. The sensitivity analysis followed by case studies conducted on IEEE-39 and IEEE-24 bus networks assesses responses to infeed loss, load rejection, cascaded tripping, and renewable energy integration, demonstrating its effectiveness. The study shows that SDLExpo collectively provides active power reserves which reduce frequency deviations, and expand the upper frequency margin to safely accommodate renewables, thereby enhancing system stability.</p>

“…The load angle is defined as the angle between permanent magnet flux linkage ψPM and stator flux linkage ψs. FRT capability studies have mainly focused on systems incorporating a power electronic converter with a control scheme, extra protective components or conventional synchronous machines [4]- [12]. The control methods lately studied are e.g.…”

Parameter Selection Guidelines for Direct-on-Line Permanent Magnet Generators Contemplating Fault-Ride-Through Capability

Direct-on-line (DOL) driven permanent-magnet generators (PMSGs) are often applied in small-scale hydropower plants (< 10 MW). The Commission Regulation (EU) 2016/631 defines the boundary conditions to operate these generators in parallel with the grid. According to the regulation, fault-ride-through (FRT) capability is required in some cases. FRT scenario of PMSGs was studied by simulations and the importance of machine parameters was analyzed. Machine parameters under interest are damper winding resistance and leakage inductance, stator resistance and leakage inductance, saliency, source voltage, total inductance and system inertia. Authors proved that fault-ride-through can be achieved by utilizing smart machine parameters selection without using complicated control systems and auxiliary equipment. FRT simulations are performed for three PMSGs and their capabilities are explored. Results can be used as a guideline in DOL PMSG design for satisfying FRT requirements. The simulation system was also verified with measurements of a 600 kW PMSG data during a fault situation: an incident where the generator was connected to the grid in phase opposition.
