“…If that fault is not cleared by relay at location ‘ B ’, relay ‘ B ’ will send a signal to relay ‘ A ’ and then relay ‘ A ’ will trip. Under system stressed conditions, the impedance seen by relay at location ‘ A ’ may pick‐up in its zone‐III, but as there is no fault, relay at location ‘ B ’ will not see any impedance in its zone‐II and thus it will not send any signal for the tripping of relay ‘ A ’ in its zone‐III 59 . The relay setting index of relay A is defined by Equation (9).

“…The nature of index in Equation (10) for stable and unstable contingencies are used as an indicator for finding the system stability. It is shown in Reference 59, that for stable disturbances the SSI response is underdamped while for unstable disturbances, SSI shows an exponentially increasing response.…”

“…A simple logical operation-based index is suggested for preventing the mal-operation of the relay in its zone-III and named as relay security index (RSI). 59 To understand the RSI, consider a fault beyond 50% of line length 'BC' in Figure 3. This fault will be in zone-III of relay placed at bus 'A' and thus the relay will be picked-up in its zone-III.…”

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.
