“…In this work, the load shedding strategy based on the UFLS relay is preferred and thereby the priority of the loads is classified as critical loads and non-critical loads. The loads connected at bus 3,4,12,15,18,26, and 28 are ranked as critical loads and the rest of the loads are non-critical loads. The system frequency response identified from phasor measurement units is used for the curtailment of a load.…”

In this modern era, the power system is stigmatized by a conglomeration of ultra-high voltage AC and DC, multi-terminal DC, and extra-high voltage AC transmission networks. It consists of a large distribution network beyond the country along with traditional generation having Ultra Mega Power Plants (UMPP) and growing ingress of Renewable Energy Sources (RES). The System Integrity and Protection Schemes (SIPS) play a crucial role in preserving a secure and reliable grid and facilitate efficient grid control during severe power system contingencies. In this paper, the operational experiences of three important SIPS in India are presented. Based on a thorough analysis, the drawbacks of these SIPS are identified and an algorithm is proposed to overcome the drawbacks using synchrophasor technology. The performance and capability of the proposed algorithm are evaluated by simulation studies on the 39-bus New England system embedded with HVDC link in MATLAB. Simulation results consummated confirm the effectiveness of the scheme in preserving system integrity. Results are validated using Electrical Transient Analyzer Program (ETAP), which is a very powerful design and analysis tool and has an extremely user-friendly interface.

“…Many authors have targeted the issues related to practical power networks such as Iran's power system area, 34 Taiwan power system, 35 Korean electric power system, 72 Hydro-Québec network, 73 Kansai electric power company, 81 Chilean power system 105 and so forth. New England 39 Bus test system is also a preferred choice of many researchers 32,36,37,54,57,[59][60][61][62][63]85 for implementing the SIPS in different scenarios. Apart from these systems, IEEE 14 bus test system, IEEE 68 bus test system and IEEE 145 bus test system are also favored by some researchers to implement the SIPS.…”

Background: An increase in the load demand has been forcing the electrical components to work near their allowable limits. The transformation of the power system in terms of technology and geographical stretch has imposed the necessity of employing advanced protection schemes in the system. The system integrity protection scheme (SIPS) has evolved as an effective measure with the gradual sprawl of the conventional grid with local measurements to a smart grid with wide-area measurement system. Aims: SIPS is a rapidly growing field in the power system and thus the study of its performance analysis, implementation methods, and applications is necessary. This paper provides a comprehensive overview of SIPS technology. Materials & Methods: In this paper, SIPS definition and classification are briefly discussed. SIPS normalization schemes that include load shedding, controlled islanding, generation rejection, ou-of-step prediction, relay settings are elaborated. To implement these normalization schemes, various methods such as index-based, optimization-based, WAMS based, EAC based, and ML-based are discussed and compared. Finally, a comparative assessment is framed based on SIPS applied for different power system issues such as transient instability, voltage instability, overloading, line contingency, protection security, etc. Results: It is observed that most of the proposed SIPS are implemented for improving transient stability. The preferred solution for implementing the SIPS by the researchers is load shedding. It is also observed that there is a lack of implementation of SIPS with renewable energy systems.

“…In recent years, the increasing low-inertia intermittent power generation and the growing frequency of extreme weather events have contributed to multiple notable blackouts around the globe [1]. As these trends are expected to continue into the future and to overlap with the preexisting challenges to secure grid operation such as electricity deregulation, the demand for novel adaptive power system emergency control and protection solutions continues to grow as well.…”

“…Unlike traditional OOS relays, controlled power system separation should coordinate the OOS detection and the subsequent line tripping actions. In the controlled splitting literature [4]- [6], the OOS detection is known as the "when to split" problem, and the splitting cutset selection is known as the "where to split" problem [1], [4]. In most of studies, these problems are considered independently from each other.…”

With the growing number of severe system disturbances and blackouts around the world, controlled system separation is becoming an increasingly important system integrity protection scheme (SIPS) to save the electric power system from a complete or partial disintegration. A successful controlled splitting approach should at least tackle the following two wellknown and interrelated problems: "when to split?" and "where to split?". Multiple previous publications consider these problems separately, and even those pursuing a combined approach propose solutions with limited applicability. In this paper, we are proposing a novel PMU-based detector of loss of synchronism that utilizes generator rotor angles and speeds to promptly detect rotor angle instabilities over a wide area. Moreover, we are showing how our loss of synchronism detection principle can be coupled with the known controlled splitting techniques to form an integrated defense scheme against unintentional loss of synchronism. The performance of this wide-area SIPS is demonstrated on the IEEE 39-bus test power system for various types of unstable conditions.
