this paper presents an application of benders decomposition to deal with the complexities in the simultaneous generation expansion planning (gep) and transmission expansion planning (tep). unlike the power system operation fields of study, the power system planning methods are not expected to be fast. however, it is always preferable to speed up computations to provide more analysis options for...

Distributed Generation (DG) is a new approach in the electricity industry to meet the electrical demand growth in a suitable manner. This paper presents a solution method for the distribution expansion panning problem including DG. The proposed algorithm is based on binary particle swarm optimization. The aim of the model is to find the optimal planning of the expansion to meet the load growth....

The rapid growth of distributed generation (DG) and load has highlighted the necessity optimizing their ways integration, as siting sizing significantly impact distribution networks. However, little attention been paid to new substations which are be installed. This paper proposes deep learning-aided joint DG-substation in network stochastic expansion planning. First, model depends on an accura...

In this paper, a novel framework is proposed to study impacts of regulatory incentive on distributed generation (DG) investment in sub-transmission substations, as well as upgrading of upstream transmission substations. Both conventional and wind power technologies are considered here. Investment incentives are fuel cost, firm contracts, capacity payment and investment subsidy relating to wind ...

In this paper, a new method is conducted for incorporating the forecasted load uncertainty into the Substation Expansion Planning (SEP) problem. This method is based on the fuzzy clustering, where the location and value of each forecasted load center is modeled by employing the probability density function according to the percentage of uncertainty. After discretization of these functions, the ...

International Electro-technical Commission (IEC) has developed a new global standard, IEC 61850 for communication systems in power substations. This standard provides interoperability among the all communication devices within the substation. This paper presents basic features of communication systems proposed by IEC 61850, such as functional hierarchy, OSI-7 layer based communication, and proc...

The electricity planning department of eThekwini Municipality performs a power system load forecast based on individual substation forecasts. The individual substation forecasts have uncertainty. It is desired to understand the effect of these uncertainties on the accuracy of the total system forecast. A Monte Carlo simulation of the forecasted system loadflow was performed. By means of this ap...

<p><span>Iraq is facing deficiency of electric power for last decades. The main reason due to less respect analytical load flow studies supply substation. To stop and overcome such situation in future, researchers should be analyzing different substation focusing on studies, short circuit protection schemes. Due lack research fault analysis, Iraq a lot issues, as failures high coppe...

Abstract The urban 35kV substation is the link between main network and distribution network, economic power supply site selection optimization are keys to coordinated planning of network. A comprehensive evaluation system established for collaborative from three aspects: social benefit, construction economy, operation combination scale expansion method rough set applied determine combined weig...

With the improvement of electric information, 3D visualization for the substation in the planning, designing, inspection, training and other aspects calls for a gradual increase. 3D rendering of the current technology is not yet mature, and equipment modelling is too complex, we propose a virtual 3D substation, which is an image-based system. The key issues include a spherebased methods of fish...
