Traditional power grid is not resistant to severe weather conditions, especially in remote areas. For some areas with few people, such as islands, it is difficult and expensive to maintain their connectivity to the traditional power grid. Therefore, a self-sustainable microgrid is desired. However, given the limited local energy storage and energy generation, it is extremely challenging for a microgrid...
Real-time awareness of the phasor state, including the volatile frequency and phase angle, is critical to maintain reliable and stable operations of the power grid. However, the high cost and low accessibility of current synchrophasors restrict their large-scale deployment over highly distributed microgrids. In this paper, we present a practical system design for monitoring the microgrid frequency...
In smart grids, the deviation of frequency and phase angle serves as an important indicator of abnormal events, the detection of which is critical to maintain reliable and stable operations of the power grid. However, the high cost and low accessibility of current power grid monitoring systems restrict their large-scale deployment over highly distributed microgrids. In this paper, we present a practical...
Information about the frequency deviation is critical to reliable and stable operation of the power grid. Current wide-area power grid monitoring systems consist of Phasor Measurement Units (PMUs) at both high-voltage transmission level and low-voltage distribution level, but are generally unsatisfactory for large-scale deployment over highly distributed microgrids in individual households and local...
