Abstract: In today’s world, a Phasor Measurement Unit (PMU) is a crucial component of our power network for managing, controlling, and monitoring. PMU can provide synchronized voltage current, and frequency measurements in real time. We can’t put a PMU in every bus in the electrical grid because it’s not viable from a productivity and economic standpoint, and it’s also not practical for handling huge data. As a result, it’s critical to reduce the amount of PMU in the power network while also increasing the power network’s observability. The optimal PMU placement problem is solved using a variety of methodologies. The paper’s main goal is to provide a brief overview of synchrophasor technology, phasor measurement units (PMU), and optimal PMU placement in order to reduce the number of PMUs in the system while maintaining complete observability and application in today’s power systems.
