Low-frequency oscillation occurs when the transmission lines equivalent impedance is small or negative. As the increase penetration of PV system, it plays an important role for system stability. A novel method for low-frequency oscillation suppression based on PV system is proposed. Model of PV accessed to power grid is established, which reveal the relationship between output power of PV system and...
The characteristic parameters of the micro-grids determine its transient response and the stability. The generation, the grid structure and the electric loads of all the whole micro-grids are always changing randomly due to the random load changes and the integration of large-scale batch energy, indicating that the characteristic parameters of the micro-grids also changes. A novel real-time and on-line...
