A multi-agent-based for fault location in distribution networks with wind power generator

Abstract

The integration of distributed generation (DG) units such as wind power into the distribution network are one of the most viable technique to meet the energy demand increases. But, the integration of these DG units into power systems can change the dynamic performances of the systems and create new challenges that are necessary to be taken care of in the operation of the network. The fault location and diagnosis are the most significant technical challenges that can improve power systems’ reliability and stability. In this paper, a Multi-Agent System (MAS) based on current amplitude and current direction measured proposed for fault location, isolation, and power restoration in a smart distribution system with the presence of a wind power generator. The agents can communicate and collaborate to locate the faulted line, then send trips signal to corresponding circuit breakers accordingly. The simulation results show the performance of the proposed techniques.

Fault Location of Distribution Network Based on Back Propagation Neural Network Optimization Algorithm

“…When the area under the ROC curve is large, the algorithm performance is better. The comparison results between the optimized BPNN and the ROC of references [24][25][26][27] are shown in Figure 9. From the graph, the improved algorithm proposed in the experiment has a larger area under the curve, indicating that this method has better overall performance.…”

“…One of the most important stability indicators is the low voltage ride-through (LVRT) capability, in which the wind energy must meet the reactive power requirements during symmetrical and unsymmetrical faults. Moreover, the grid codes should be within the primitive values to protect the WT and maintain the connection during grid fault conditions (Azeroual et al, 2021;Mahmoud et al, 2019aMahmoud et al, , 2019b. There are several LVRT and high voltage ride-through (HVRT) grid codes, and each country has different values for recovery voltage.…”
