Impact of Flexible Operation on Resilience and Reliability in Multi-Carrier Grid

Abstract

Due to the increasing need for various types of energy carriers and clean energy, the importance of exploiting and using renewable resources increases. This article aims to have a multi-carrier micro-network that can be resilient against major incidents and has adequate reliability. To achieve these goals, flexible operation of the grid under investigation is done. Then, the new reliability parameters are checked, and the resilience of the multi-carrier network with variable risk coefficients is checked in a short period of 24 hours. The investigated multi-carrier network has electricity and gas energy input. And it has electricity and heat at the output. The multi-carrier network consists of transformers, CHP, electrical and thermal storage and PHEVs. The results indicate the proper operation and reliability improvement as well as maintaining the resilience of the network in dealing with high risk incidents. Also, the network has been able to perform well for incidents with medium risk.
