In recent years, significant research efforts have been devoted to the optimal planning of power systems. Substation Expansion Planning (SEP) as a sub-system of power system planning consists of finding the most economical solution with the optimal location and size of future substations and/or feeders to meet the future load demand. The large number of design variables and combination of discr...

Due to the important increase of the power of electrical transmission and distribution grids expected for the following years, especially in developing countries such as Kenya, Brazil, Philippines or Mexico among others, that have planes of generating energy from clean sources far away from the centres of consumption [1] it becomes a matter of special importance adapting and developing new subs...

Successful operation of entire power system depends to a considerable extent on efficient and satisfactory performance of substations. Hence substations in general can be considered as heart of overall power system. In any substation, a well designed grounding plays an important role. Since absence of safe and effective grounding system can result in mal-operation or non-operation of control an...

A new method to solve the single and multi-objective distribution expansion planning problems including DG is investigated in this paper. The sizing and placement of DG as well as the required power of the main grid would be optimized using proposed method to meet the demand. Binary Particle Swarm Optimization (BPSO) algorithm is used to solve the optimization problem for three objective functi...

When a power utility considers the introduction of a new component in their substation, it is primarily faced with costs. Each proposed investment must be defended facing the management. In the simplest situation a new component with higher performance will just be substituted for an older one. In this case the existing methodologies are sufficient to assess the economic impact of the investmen...

In order to study the electromagnetic compatibility of a power system, authors adopted an effective analysis software and proposed a new prediction method. First, simulated and analyzed the electromagnetic transient when switching the no-load bus in the 500kV substation by the ATP software and proved the simulation results were consistent with the actual results; Second, introduced the Gray pre...

This paper addresses implementation requirements for a fully automated substation data integration and fault analysis for power system transmission lines. The approach is based on measurements from substation intelligent electronic device recordings. The proposed architecture provides a transparent approach to substation data management, analytics functions, as well as the visualization of the ...
