Voltage Control of Distribution Networks to Increase their Hosting Capacity in South Korea

This paper presents the results of a study of a voltage management technology called parameter determination of voltage regulator (PDVR) implemented in a 22.9 kV distribution network. Korea Electric Power Corporation has developed this PDVR technology for increasing the hosting capacity without causing any voltage problems in LV (220/380 V) networks. PDVR calculates and provides the operation settings of voltage regulators such as on load tap changer, pole mounted automatic voltage regulator, and distributed generation (DG). Subsequently, these settings are applied to the voltage regulators, which further optimize the 22.9 kV network voltage without the control of the distribution management system (DMS). A study of the operations and performance of PDVR through the analysis of test results is presented in this paper.
