Abstract
Despite distributed generations (DGs) advantages, the presence of them can cause glitches in distribution networks. One of the typical glitches is a mismatched fuse and recloser in temporary short circuits, which is often remedied by fault current limiter (FCL). By calculating the expected benefits to distribution companies (DISCOs) in various value of loss load scenarios, once the uncertainty output of DGs is considered, this paper examines the effectiveness of FCLs in solving drawbacks and improving reliability. FCL can improve network reliability in one of two ways: a) the FCL can reduce the magnitude of fault current, thereby decreasing the failure rate of protective devices, b) the FCL can correct a mismatched fuse and recloser, resulting in a lower energy not supplied (ENS) rate. The present paper uses the biogeography-based optimization method to measure optimal FCL impedance in terms of maximizing the DISCO’s benefit after FCL installation. Using simulated performance on a test distribution system, FCL network penetration is founded to resolve the identified problem by improving the ENS rate.
