Quantifying the Contribution of Distributed Energy Resources to Power Systems Resilience
MetadataShow full item record
Distributed energy resources have a large effect on the power system resilience once integrated to various power system networks. However due to the low frequency high impact events affecting power systems, there has been a increase in power outages leading to the importance of power systems resilience. The clarity on the concept of power systems resilience is relatively low but quanti fication can be achieved through the use of resilience metrics and employing a good load restoration scheme based on the contribution of distributed energy resources upon the occurrence of low frequency high impact events. The area of study being Karamoja situated in northern Uganda having several distributed energy resources connected to its power network along the main grid evacuated from Umeme. A case study is originated from an IEEE 12-busbar system of Karamoja transmission and distribution network to investigate the effect of distributed energy resources to power system resilience. A sequential Monte carlo simulation is done using the DigSILENT power factory software with DER penetration levels as a basis for showing the contribution of distributed energy resources.
