“…In this high‐speed ABOP, the logic circuit controlled the backup relay that tripped a three‐phase pole breaker in a radial power system. In fuse relay adaptive overcurrent protection schemes for microgrids with distributed generators, the backup relay settings were selected according to the microgrid circuit paths, and maximum ampere rating fuses on feeder busses, but without using fuse‐switch sensors and logic for the fuse feeders. In future research, the high‐speed ABOP with fuses, sensors, and logic will be modified for using with single‐pole breakers to integrate with nonradial power systems.…”

“…At a fault situation, the maximum phase secondary current of breaker poles was selected to calculate the multiple of pickup (tap), and consequently calculated the relay's operating time to trip the breaker. In adaptive overcurrent protections, relays could be set by using the relay's PSL or resident functions . This high‐speed ABOP on fuse feeders with sensors was based on using the relay's PSL instead of using relay's resident functions.…”

Summary In traditional power distribution systems, feeder fuses are coordinated with a backup relay without using adaptive protection and sensors. The backup relay is set by selecting the maximum fuse ampere rating and using the relay's resident functions. Because of this, the backup relay is set at the same inverse time‐current curve for all fuses. In this study, to improve the speed and selectivity of the backup relay at busses with different fuse ampere ratings, the backup relay was set at different inverse time‐current curves depending on the maximum ampere rating of the fuses they are connected to. Tests for the adaptive backup overcurrent protection showed how the backup relay selected the settings based on the connected maximum ampere rating fuse, and the relay speed increased up to 32.86%. The backup relay adaptive protection improved the selectivity and speed for clearing the faults, respect to the nonadaptive protection.

“…The level of fault current, in addition to the selection and coordination of protective devices, are the main challenges of the microgrids incorporated with the wind [110]. Among many solutions adaptive overcurrent protection scheme [116], centralized communication with a localized backup scheme [117], fault distance estimationbased protection scheme [118], fuzzy inference system based scheme [119], microprocessor-based scheme [120], oscillation frequency and transient power-based scheme [121], parameter estimation approach [122], and voltage-currenttime inverse-based scheme [123], are widely used protection schemes.…”

The strengthening of electric energy security and the reduction of greenhouse gas emissions have gained enormous momentum in previous decades. The integration of large-scale intermittent renewable energy resources (RER) like wind energy into the existing electricity grids has increased significantly in the last decade. However, this integration poses many operational and control challenges that hamper the reliable and stable operation of the grids. This article aims to review the reported challenges caused by the integration of wind energy and the proposed solutions methodologies. Among the various challenges, the generation uncertainty, power quality issues, angular and voltage stability, reactive power support, and fault ride-through capability are reviewed and discussed. Besides, socioeconomic, environmental, and electricity market challenges due to the grid integration of wind power are also investigated. Many of the solutions used and proposed to mitigate the impact of these challenges, such as energy storage systems, wind energy policy, and grid codes, are also reviewed and discussed. This paper will assist the enthusiastic readers in seeing the full picture of wind energy integration challenges. It also puts in the hands of policymakers all aspects of the challenges so that they can adopt sustainable policies that support and overcome the difficulties facing the integration of wind energy into electricity grids. INDEX TERMS Angular stability, energy storage system, fault ride-through capability, frequency response, grid codes, reactive power support, voltage stability, wind intermittency. • Induction generator (squirrel cage (type 1) and wound rotor (type 2))

In recent times, real-time simulation has been used to validate the testing and design of protection, control, and communications systems prior to their commissioning in the field, which has improved the reliability and security of the commissioning processes for electrical systems. This paper reviews the state-of-the-art and future trends in protection, control, and communications testing of electrical grids using real-time simulation. In addition, a summary is presented in which all the works and technologies mentioned are listed with the purpose of identifying new challenges in the proposed topic. Finally, future trends related to the use of real-time simulation for evaluating protection, control, and communications schemes are presented. Real-time simulation is very useful due to the increasing complexity of modern electrical power systems, therefore, it is necessary to use this kind of tool to facilitate field testing, avoid unnecessary work, and reduce costs for clients.
