With the increasing pressures on energy conservation and emission reduction, the urgent need arises to increase the maximum penetration of distributed generation (DG) without violating the voltage limits. This paper proposes a two-dimensional multi-resolution model of smart distribution grid (SDG) to analyse dynamic changes of DG and load at first. And then based on the model, an analytical methodology...
The interconnection of distributed generators (DGs) into distribution systems causes several adverse effects to the overcurrent based protection system coordination. These adverse effects are loss of coordination, loss of sensitivity, bi-directionality of protection devices, fuse nuisance blowing, and temporary overvoltage. This paper provides general guidelines about the maximum penetration of DG...
We present an investigation on the optimal aperture, both its size and current source distribution, for the maximum penetration of signals in near-field applications. The near-field beam radius is calculated for different size of the uniform Huygen's source distribution so that the optimal size of a uniform Huygen aperture is concluded. For a general aperture distribution, both analytical methods...
In this paper a method is proposed to determine the optimum allocation of the maximum distributed generation penetration in medium voltage power distribution networks. The method is based on an already-known but suitably modified and optimized method. Technical constraints, such as thermal rating, transformer capacity, voltage profile and short-circuit level are considered. A real network with already...
This paper investigates the results of distributed generation penetration in a medium voltage power distribution network. The network is located in West Macedonia, Greece. The connected distributed generation resources are in their entirety small hydroelectric plants. Their locations and ratings are predetermined. Only technical constraints such as thermal current, transformer capacity, voltage profile...
