Abstract: Formation control of multi-vehicle system has been studied as a combination of estimation problem and tracking problem. Virtual structure based formation control strategy is applied which solves the problem of formation maintenance and movement using a control architecture in hierarchical manner. The control architecture is distributed in nature and requires only local neighbor to neighbor communication which consists of three layers: formation state estimator, formation control module and the physical agent. In particular, a PID-like discrete-time consensus algorithm is applied on group level to estimate the time varying group trajectory information. Based on the estimated group trajectory information, a PID-like discrete-time consensus algorithm based tracking controller is applied on vehicle level. Numerical solution presented in the end, verifies the effectiveness of proposed approach.

Abstract: The paper presents voltage stability margin (VSM) of radial distribution network by considering a unique reactive loading index without and with distributed generator (DG). It is shown that the branch, at which the value of reactive loading index is minimum, is considered to be the weakest branch of the system. Then, the voltage stability margin (VSM) of the feeder is selected heuristically. It is the product of reactive loading indices of all branches of the feeder. The VSM of all feeders can be evaluated. The feeder which has the smallest value of VSM can be considered as the weakest feeder of the system and is at the proximity of voltage collapse. So, for multiple feeders, the voltage stability margin of a system may be considered as the VSM of the feeder which has the smallest value. The effectiveness of the proposed VSM without and with considering DG has been successfully tested on a 12.66 kV radial distribution network consisting of 33 nodes and the results are found to be in ve
