“…Synchrophasors technology is a time-synchronized technology that measures both the phase angle and magnitude of voltage in a power system that is time-synchronized to capture the coherent picture of the entire grid. These are estimated by high-speed devices called PMUs [13]. The schematic diagram of the PMU based wide-area monitoring and control system is shown in Figure 1.…”

The complexity and dynamics of the modern power system are continuously changing due to the penetration of a large number of renewable energy sources and changing load patterns. These growing complexities have caused numerous outages around the world, primarily due to the lack of situational awareness about the grid operating states. Rectification of this problem requires advanced sensing technology to accurately capture the dynamics of the system for better monitoring and control. Measurement of synchrophasors is a potential solution to improve situational awareness in the grid. The synchrophasors technology is now widely accepted throughout the world and has the potential to replace the existing SCADA system in monitoring and control of the power system. Their installation enables efficient resolution to substantially improve transmission system planning, maintenance, operation, and energy trading. This paper reviews the state of the art potential applications that the PMU based WAMC offers to the power system. It also includes technical perspectives, challenges, and future possibilities.

The integration of distributed generations (DGs) in power systems poses challenges in coordinating protection devices originally designed for a centralized generation. This study examines numerous scenarios for choosing and coordinating protection systems in presence & absence of DGs and provides a thorough analysis of how DGs impact protection coordination. The technique takes into account a variety of relay attributes and use Teaching Learning Based Optimization (TLBO) algorithm to ascertain ideal relay configuration that will enable most efficient coordination. Optimization techniques are employed to optimize the zones of distance relays and ensure a suitable coordination time interval (CTI) [0.2 sec or more]. Simulation results on real-time networks, such as the IEEE-9 and IEEE-30 bus test systems, demonstrate the effectiveness of the method in achieving optimal coordination. TSM and over-current relay characteristics are found for various cases and uniform values in every situation to prevent relay resets. Using the TSM and Characteristics values operating time of overcurrent relays and the operating time of the second zone of distance relays are found. The simulation outcomes showcase the ability of the method used to generate practical and feasible solutions.
