Protection of Active Distribution Systems and Microgrids: A Review on Challenges and Solutions
Paper i proceeding, 2021

Operation of distribution systems is becoming more complex by hosting various emerging technologies such as distributed generation, energy storage systems, electric vehicles, information and communication technologies, etc. Further, the concept of microgrid is becoming more pragmatic and accessible. This transition not just brings benefits such as advanced demand response, enhanced resiliency, etc., but also several operational and protection challenges for the utilities. The protection challenges are mainly caused by the bi-directional power flow, change in short-circuit level, fault current limitation in converter-dominated active distribution systems and microgrids. In concurrence with this transition, there is also an enormous rise in advanced artificial intelligence techniques such as machine learning, data-mining, etc. This paper presents a categorical review of the traditional protection methods based-schemes proposed for the active distribution systems and microgrids in the grid-connected and islanded modes of operation. The paper further presents a comprehensive review of protection schemes employing special techniques. Finally, an assessment of the advantages and shortcomings of the reviewed protection schemes is presented in the paper.
