This paper considers an increasing problem in the consumer end of the electrical grid. The ongoing change from constant impedance loads towards constant power characteristics in new household electrical appliances may affect the network voltage stability. Can the smart grid development disarm this potential threat? This work points out an important target for load modeling in network simulation.
The issue of power quality in distribution networks is urgent for Russia and this situation is first of all caused by high harmonics. These networks supply power to many nonlinear loads (electric transport, industrial power electronics, rectifiers, etc.) There is a tendency toward increase in the nonlinear load. High harmonics in the supply network considerably decrease the efficiency of both network...
The paper proposes a new approach for optimization of power system states with Smart grid utilities. Original formulae establishing the dependence of power system state parameters on those of network devices have been presented. An approach developed by authors has been examined to define zones of influence of control units and to find best places for their installation in power systems. The efficiency...
The issue of intelligent electric power industry, in particular Smart Grid, has become a strategic priority of energy policy of the world's leading countries. Analysis of documents determining the prospects for the electric power industry of developed and developing countries for 20 years ahead and further shows that the application of Smart Grid technologies is considered as a means of solving a...
