Quantitative Benefit Analysis of Adaptive and Conventional Distance Protection Parameterizations

Conventional grid protection is parameterized with a single generalized parameter set for a variety of different operating scenarios. With an increase in installation of distributed variable energy resources and grid reinforcements, the variety of scenarios increases and an optimal protection can no longer be guaranteed. Furthermore, renewable energy infeed is limited when protection is not guaranteed. Hence, this paper compares a new adaptive parametrization approach with standard methods applying simulations in Mat-lab/Simulink, focusing on a distance protection model adjusted for grid topology and feed-in changes. Consequently, this paper aims to confirm not only the benefit but also the necessity of adaptive distance protection in future grids. The effectiveness of both protection methods is tested within various scenarios, emphasizing fault detection, tripping time, and fault location accuracy. The results show that the adaptive concept offers enhanced reliability which will result in significant financial benefits, recommending its adoption in renewable energy systems.
