Use of uncertainty function for identification of hazardous states of atmospheric pollution vector

Boris Pospelov,Evgeniy Rybka,Ruslan Meleshchenko,Olekcii Krainiukov,Serhii Harbuz,Yuliia Bezuhla,Ihor Morozov,Anna Kuruch,Olena Saliyenko,Ruslan Vasylchenko

The use of estimation of the values of the uncertainty function to identify hazardous states of an arbitrary atmospheric pollution vector is considered. At the same time, it is proposed to estimate the uncertainty function in a fixed-width window moving a... see more

A Vector-Controlled Distributed Generator Model for a Power Flow Based on a Three-Phase Current Injection Method

Pyeong-Ik Hwang, Seung-Il Moon and Seon-Ju Ahn

This paper proposes a vector-controlled distributed generator (DG) model for a power flow based on a three-phase current injection method (TCIM). In order to represent the DG models in the power flow, steady-state phase current output equations are formul... see more
