Methods of linear and nonlinear state estimation of distribution network

Golub I., Boloev E. Methods of linear and nonlinear state estimation of distribution network // E3S Web of Conferences. Vol.58. ID: 03010. 2018. DOI: 10.1051/e3sconf/20185803010 The paper proposes a new approach to the problem of state estimation of a low voltage distribution network by the measurements coming from smart meters. The problem of nonlinear state estimation based on the measurements of nodal powers and voltages is solved by the method of simple iteration which minimizes the quadratic...

Developing a Procedure for Segmenting Meshed Heat Networks of Heat Supply Systems without Outflows

Tokarev V.V. Developing a Procedure for Segmenting Meshed Heat Networks of Heat Supply Systems without Outflows // Thermal Engineering . Vol.65. No.6. 2018. P.400-409. DOI: 10.1134/S0040601518060101 The heat supply systems of cities have, as a rule, a ring structure with the possibility of redistributing the flows. Despite the fact that a ring structure is more reliable than a radial one, the operators of heat networks prefer to use them in normal modes according to the scheme without overflows...
