Sažetak

This paper analyses the problem of voltage control by step voltage regulator (SVR) in the primary feeder with large-scaled PV systems, and presents operation ranges and the voltage control limit of micro hydropower generator (MHG) with power factor (PF) control function. In addition, this paper evaluates the voltage impact in primary feeders depending on voltage control modes of MHG, and then proposes an optimal voltage control algorithm. Furthermore, from the simulation results based on the proposed algorithm, it is verified that it can contribute to voltage stabilization in the distribution system with large-scaled PV systems.
