Distributed renewable generation is increasing all over the world. The effect of Distributed Generation (DG) on system voltage profile can be examined through sensitivity studies. The sensitivity matrix depicts variations in the voltage magnitude with respect to changes in active and reactive power associated with loads and local generation at different buses in the system. This sensitivity matrix...
This paper addresses the impact of variable solar PV generation on voltage profile and determines maximum allowable active power injection by solar PV generation in distribution system. Investigation is carried out using sensitivity analysis methodology and tested on a sample MV (Medium Voltage) distribution system. Variability of power production using solar PV system is determined by estimating...
The rapid growth of grid-connected distributed generation has increased the likelihood of over-voltage occurrences in distribution networks. In recent times, much research has taken place in order to develop a control strategy to mitigate the voltage rise problem. However, most of the published strategies require re-tuning when additional resources are connected, or have a strong dependence on network...
With an increasing penetration of solar photovoltaic (PV) systems, power distribution grids are becoming more susceptible to network voltage rise. As per applicable standards for grid-integrated PV systems, a PV system must be automatically disconnected from the grid when the terminal voltage of the PV system exceeds a defined maximum voltage. With this directive, in certain situations, PV systems...
