Title
A Protection Scheme for Microgrids Using Intelligent Relays
Abstract
Microgrids are emerging as an important part in modern power distribution systems due to significant development in distributed generation technologies. Microgrids operate with a high level of inverter interfaced distributed generation (IIDG) penetration such as fuel cells, solar cell, and battery storage etc. The problem of microgrid protection becomes challenging as the fault current varies widely depending upon the operating conditions such as grid-connected and islanded mode in presence of IIDG. Fast and accurate fault detection coupled with a clearing mechanism is required for a safe and secured micro-grid operation. The relay detects and classifies faults using local measurements irrespective of the operating mode of the micro grid. The process starts by measuring and pre-processing the current signal at the relaying point using the Wavelet Transform. Time-frequency features such as change in energy, entropy and standard deviations are calculated using the wavelet coefficients. Cases representing various faulted and normal conditions are simulated to generate the complete data set containing the above mentioned features.
