Black Start Application in Power System Restoration using Distributed Energy Resources Ye-Obong Udoakah, Emmanuel Mudaheranwa, Jun Liang, Liana Cipcigan

Abstract

The threats to the power systems being caused by extreme weather-related events are increasingly alarming. Safeguarding the Power System against all forms of instability requires adopting new and integrated approach. The integration of the distributed energy resources (DERs) into the Power grid especially at the distribution level has greatly changed the dynamics of the modern power system. Improving the resilience of the power grid by the application of DERs in black start application is explored in this study. The black start restoration is formulated as a dynamic optimisation problem and the restoration sequence capable of improving the grid resilience is developed. The implementation is carried out on the Nigerian 48-bus system and the simulated results demonstrate the DERs ability in contributing significantly to power system black start.
