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 ...

Developments in computer and communication technologies have enabled unmatched integration of a wide range of substation functions within a computer control system. This new class of application has gone through a great deal of effort into achieveing cost-effective, efficient, secure and high performance of the utility power grid substation operations. The integrated Substation Control System (...

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...

In this paper, we present a model developed for Electric Power Management Systems (EPMS) and Supervisory Control and Data Acquisition (SCADA) systems that allows us to calculate device vulnerability and help power substation operators and administrators identify and harden those portions of the control system that are most vulnerable to cyber attack. We use graph theory to model electric power ...

Modern society is unquestionably heavily reliant on supply of electricity. Hence, the power system is one of the important infrastructures for future growth. However, the power system of today was designed for a stable radial flow of electricity from large power plants to the customers and not for the type of changes it is presently being exposed to, like large scale integration of electric veh...

Within the hierarchy of power system, distribution system automation plays a crucial role to provide reliable service to customers. Though initially computer aided automation started as substation monitoring system (SMS) just for monitoring some key parameters such as voltage and currents of different components in a substation, the technological advancement has enabled to have access to more f...
