“…Sensitivity is the ability of the protection system to quickly detect and isolate faults before the power grid's stability margins are violated. Selectivity is the capability of the protection system to isolate the fault such that the least number of loads are affected by a power outage [1]. As discussed in [2]- [4], the role of protection system is to enhance the power system's reliability and resilience and to avoid major outages with possible cascading effects.…”

Adaptive protection is defined as a real-time system that can modify the protective actions according to the changes in the system condition. An adaptive protection system (APS) is conventionally coordinated through a central management system located at the distribution system substation. An APS depends significantly on the communication infrastructure to monitor the latest status of the electric power grid and send appropriate settings to all of the protection relays existing in the grid. This makes an APS highly vulnerable to communication system failures (e.g., broken communication links due to natural disasters as well as wide-range cyber-attacks). To this end, this paper presents the addition of local adaptive modular protection (LAMP) units to the protection system to guarantee its reliable operation under extreme events when the operation of the APS is compromised. LAMP units operate in parallel with the conventional APS. As a backup, if APS fails to operate because of an issue in the communication system, LAMP units can accommodate a reliable fault detection and location on behalf of the protection relay. The performance of the proposed APS is verified using IEEE 123 node test system.

“…The majority of the feeder's loads are situated on the laterals. The feeder is the inherently unbalanced because of the unequal (unequality) spacing of the laterals and uneven distribution of the single phase loads [2]. The current built up very quickly because of shunt faults in power system.…”

“…The secondary or backup relay should take over tripping only if the main relay fails to operate fails to operate. The relay may get mal operated if backup relays are not properly coordinated [1,2].The purpose of relay coordination is to ensure that in the event of a power system failure, the protective relay is required to isolate only the faulty part of the power system from the healthy network and should operate as quickly as possible to keep the healthy network of the system in normal condition. Optimal relay coordination can be achieved by selecting optimal relay settings, namely Plug Setting (PS)and Time Multiplier Setting (TMS).…”

“This paperis proposes a novel nature-inspired meta-heuristic optimization algorithm, called Whale Optimization Algorithm (WOA), which mimics the social behavior of the humpback whales. The algorithm is inspired by the bubble-net hunting strategy”which is good comparing to others. WOA is tested with 29 mathematical optimization problems and structural design problems. Optimization results prove that the WOA algorithm is very competitive compared to the state the of art meta heuristic algorithms as well as conventional methods

“…Long transmission lines are generally protected by distance protection as both main and backup protection. A distance relay can be categorized based on its operating zone characteristics, like quadrilateral, elliptical, lenticular, polygonal, and mho-based protection scheme [1]. The characteristic of a distance relay is defined during the commissioning of a protection system considering different network contingencies.…”

The operation of a distance relay is a function of source impedance and fault parameters. The performance of a distance relay is quite stable when used for the protection of a strong power system network where the fault current contribution is dominated by synchronous machines. However, their performance is affected when the synchronous machine is replaced by high internal impedance-based generation as seen in the case of renewable energy source (RES) based generating units like solar and wind. The RES results in an observable increase in source to impedance ratio (SIR) and significantly affects the operating performance of a distance relay. The dynamic change in infeed in the RES system leads to overreach and under-reach problems. The dynamic nature of RES arises revision in the reach settings of the distance relay placed in the RES integrated network. This problem is stimulated for a model transmission system in the real-time digital simulator with hardware in loop simulation installed at Central Power Research Institute Bangalore, India. The performance of the relay is studied for high SIR, infeed variation, and load encroachment. Observation and simulation results recommend the rising requirement of an adaptive distance relaying protection scheme that can dynamically manage the relay zone setting as per the operation network configurations.
