ASSESSMENT OF THE VOLTAGE STABILITY LOAD INDEX OF ELECTRIC NETWORKS BASED ON THE ECHO STATES NETWORK USING THE PHASOR UNIT

The issue of power system voltage stability, which is one the key issues in process planning and operation system, considered paper. It noted that neural networks have now been tested a number technological incidents form instability various countries. problem possible risk failure due to loss its stability energy during investigated. this regard, conducting analysis an important procedure order timely identify buses with low reliability within system. Thus, control personnel should take certain measures avoid any cases drop purpose paper present new method for estimating load index (L-index) using data from optimally placed phasor units (PMUs). evaluated work recurrent network known as echo state (ESN). PMU optimal placement made taking into account island operating conditions. results PMUs normal boundary conditions, well evaluation L-index ESN IEEE 14 bus are presented. A technique based on states measurements An estimate performance has performed; shown high accuracy under disturbed proven development efficient provides accurate computations.
