Abstract
Abstract Adaptive protection is an efficient way to tackle the changing topologies in distribution grids caused by the penetration of renewable energy sources. Effective operation of an adaptive protection scheme requires a fast and reliable communication network. However, inherent time delays can adversely impact the effectiveness of Adaptive Protection Schemes (APSs). This manuscript classifies delays into two types and proposes a method or each type to overcome the effects caused by the corresponding type of delay with an improved APS algorithm. The algorithm uses a combination of centralized and decentralized signaling to counter different types of delays. The improved algorithm is tested on a Canadian 9 bus urban benchmark distribution network. MATLAB Simulink environment is used to simulate the 9 bus benchmark distribution network. The results obtained are demonstrated with the improved scheme on stated test system.
