“…A free-node can be grouped into any island. Since the aim of the proposed ICI method is to find an islanding solution, instead of identifying the generators within each coherent group, this work can adopt the approach presented in the existing literature, such as those described in [23], [24].…”

Abstract--Power systems are prone to cascading outages leading to large-area blackouts, and intentional controlled islanding (ICI) can mitigate these catastrophic events by splitting the system into sustainable islands. ICI schemes are used as the last resort to prevent cascading events; thus, it is critical to evaluate the corresponding system risks to ensure their correct operation. This paper proposes a unified framework to assess the risk of ICI schemes. First, a novel ICI method to create islands with minimum power imbalance is presented. Further, a risk assessment methodology is used to assess the probability and impact of the main operational modes of the ICI scheme. The unified framework provides insights on the benefits of implementing ICI, considering the uncertainties related to its reliability. The ICI scheme is demonstrated using the IEEE 9-bus system. The proposed unified framework is then fully deployed on the actual power system of Cyprus. Multiple case studies on the real network are created to demonstrate the adaptability and robustness of the proposed scheme to different system conditions. The adoption of the unified framework highlights that the system risk significantly reduces with the ICI in service, even when the reliability uncertainties associated with the scheme are considered.

“…Related to this is the question of how to associate load buses and transmission lines with synchronic groups. In the context of slow-coherency, references [18] and [19] represent two approaches to addressing this task. From the point of view of synchrony, the discussion in Step 5 points to the considerations that are involved, and we expect to investigate these issues further.…”

“…Since this approach takes into consideration only steady-state constraints, an approach considering transient simulations is presented in [4]. In [5], a slow coherency technique is used to group both generators and load buses in a single group considering the closeness of each other. This approach uses the slow eigenbasis theory to collect coherent groups.…”

Abstract--This paper proposes a new method for optimal placement of Phasor Measurement Units (PMUs) across the weak areas of the power system to monitor the status of the boundary buses during Parallel Power System Restoration (PPSR). The proposed PMU placement method is based on an Integer Linear Programming (ILP) methodology. For validation purposes, the proposed method is implemented across the weak areas of the following two test systems: New England 39-bus test system and IEEE 118-bus test system. Index Terms--Parallel power system restoration, phasor measurement unit, power system restoration, slow coherency, synchronised measurement technology, weak area, weak connection.
