Voltage and Current Sensor for State Estimation in Distribution Network with Generation

Abstract

The penetration of Distributed Generation into the distribution networks has been increasing during the last decades. However, the increase of generation brings additional technical challenges for the Distribution Network Operators. Thus, the integration of Distributed Generation along with the improvement of the quality of service is driving Distribution Network Operators to actively control their networks. In order to achieve an effective control of the distribution network it is necessary to estimate the voltage on the network. This paper presents a method to accurately estimate voltage on the MV Network from limited measures of voltage and current. A method to determine the best location to place those voltage and current sensors is also explained.
