The recent development of dispersed generation leads to fact that distribution grids have to deal with the bidirectional power flow which may cause voltage rise above permissible level. Currently used voltage regulation scheme cannot completely and successfully cope with this problem. As a result of the further increasing penetration of distributed generation, the new voltage regulation system will...
This paper presents two optimal setting methods for transformers with line drop compensator and step voltage regulator, and analytical tools considering interconnection of distributed generators. The optimal setting problem can be formulated as a large combinatorial optimization problem, in which the setting values of voltage control equipment is utilized as state variables. The first and original...
One of the major problems in development of distributed generation (DG) is voltage control derived from reverse power. In order that voltage variation may not degrade customer voltage supply quality, feeder voltage should be maintained within the permissible range against DG connection. To improve the voltage profile in distribution network with DG, this paper proposes several voltage control strategies...
This paper contains technical recommendations for power flow representation of wind power plant (WPP) in large-scale positive-sequence power flow simulations. These guidelines were prepared by the Wind Generator Modeling Group (WGMG) of the Western Electricity Coordinating Council (WECC).
This paper presents the application of a suitable control strategy for multibus microgrid applications. The control strategy, used with each distributed generation system in the microgrid is developed so as to combine the advantages of the current control and the voltage control strategies. The performance of the proposed application in terms of power management has been verified in simulation on...
