Abstract

This A new methodology to find Normally Closed (NC) switches optimal location in a Medium Voltage (MV) distribution network is presented. This methodology is based on the minimization of Energy Not Supplied (ENS) for the whole electric system, considering the possible NC switches locations in every feeder. This methodology considers also the NC switches previously installed in the MV network, as well as the Normally Open (NO) switches and the independent sources. Reliability data relating to power lines and independent sources are necessary. The ENS cost for each client or load is also considered. Finally, the proposed methodology can help a system operator to evaluate the economic impact of new NC switches in a given distribution system
