“…Therefore, probabilistic studies are proposed for analyzing transient stability in renewable rich power networks [32]. In addition, phasor measurement unit (PMU)-based real-time transient stability monitoring and analysis schemes are also proposed [33,34] by researchers, and such methods are vital in mitigating potential instability scenarios in real-time due to uncertainties associated with renewable generation.…”

The energy sector is currently undergoing a rapid transformation with the integration of power electronic converter (PEC)-interfaced renewable energy sources (RES), such as wind and solar photovoltaic (PV) systems, at both the transmission and distribution networks. Power system stability has been significantly influenced by this power grid transformation. This paper comprehensively reviews major power system stability issues affected due to large-scale integration of PEC-interfaced RES in power grids, with some example case studies relevant for each stability category. According to the review, stability issues are mainly originating from reduction in synchronous inertia, reduction in reactive power reserve, low short-circuit strength of the power network, and fault ride-through (FRT) strategy/capability of the PEC-interfaced RES. Decrease in synchronous inertia could affect both the rotor angle stability and the frequency stability, while decrease in short-circuit strength and reactive power reserve could cause voltage stability and rotor angle stability issues in power networks. Sub-synchronous control interactions are also receiving a lot of attention by the power industry due to increasing oscillatory stability incidents reported in power networks with PEC-interfaced RES. FRT capabilities/strategies of PEC-interfaced RES are also playing a pivotal role in power grid stability due to its influence on active and reactive power, hence more emphasis should be placed on FRT schemes of PEC-interfaced RES, since future power grids are expected to operate with 100% PEC-interfaced generation sources. Stability improvement strategies could be implemented to address multiple stability issues in PEC-interfaced power networks; however, rigorous stability studies are required to identify the optimal conditions to implement these improvement strategies. Furthermore, ongoing structural changes in power grids to accommodate remotely sited PEC-interfaced RES are also influencing the stability of power grids. Therefore, all these factors must be carefully considered by system operators when planning and operating power grids in a secure and stable manner with high penetration levels of PEC-interfaced RES.

“…When all the Lyapunov exponents are computed, they are averaged by (9). Once all indices are computed, the ranking of severity is defined by applying weight factors to the indices, as shown in (11), which enables the sorting of all disturbances.…”

“…In [9], [10], a collection of stability indices shows that the angle and rotor angle speed variables of synchronous generators are widely used, resulting in up to 13 stability indices, and being the most used those associated with the rotor angle of synchronous machines. For instance, authors in [11] have proposed the angle stability limit that evaluates the relationship between active power and rotor angle to different contingencies, yielding a region that indicates the stability limits per magnitude. In [12], the critical clearing time (CCT) index is used to determine the maximum time to clear a fault and a stable region that is bounded and defined when the clearing time is greater than the CCT.…”

This paper adopts a methodology to assess and rank the severity of the most frequent disturbances, 3 types in particular, that occur in the Mexican Interconnected System (MIS) when wind power plants (WPPs) are integrated. This is done by combining three stability indices from which an overall performance measure can be derived. In this way, it is possible to assess the severity of the disturbances such as generation tripping, line tripping and disconnection of loads. The indices under consideration include measures such as maximum amplitude, speed variation, and the Lyapunov exponent. For ranking the severity, a general index value is used. To confirm the effectiveness and performance of the proposed methodology, this paper investigates the 190-bus and 46-generator MIS equipped with an 8% of wind generation to quantitatively evaluate the severity of disturbances, resulting in 66% of unstable disturbances which are associated with the disconnection of loads.
