Study of double short circuits on earth in 10 kV power grids with isolated neutral and with high level penetration RES

Abstract

Proposed study described positive influence of high level penetration of renewable energy sources in distributed electrical networks for power system in total in war conditions. Faults in transmission power lines are analysed and shown depend on level voltage. The paper presents the results of studies of double earth faults in 10 kV networks with an isolated neutral in the MATLAB program package.
