This paper proposes the problem of supply restoration in faulty power distribution systems as a benchmark for planning under uncertainty. This benchmark, which is derived from a significant realworld case, is both simple to understand and easily scalable. The goal is to reconfigure the distribution network to resupply a maximum of consumers affected by the faults. Due to sensor and actuator unc...

despite the presence of women in higher education and qualification levels of public decency, a small number of women have been appointed to management positions; therefore, they are less powerful than men in organizational decision-making processes.  in this research, organizational culture and consequently gender as the most important factor influencing corporate power distribution is conside...

Power flow analysis is the backbone of power system analysis and design. They are necessary for planning, operation, economic scheduling and exchange of power between utilities. Power flow analysis is required for many other analyses such as transient stability, optimal power flow and contingency studies. The principal information of power flow analysis is to find the magnitude and phase angle ...

A robust methodology for obtaining the steady-state solution of the power grid is essential for reliable operation as well as planning of the future transmission and distribution grid. At present, disparate methods exist for steady-state analysis of the transmission (power flow) and distribution power grid (three-phase power flow). All existing alternating current (AC) power flow and three-phas...

The penetration of distributed generation and wind power in particular is expected to increase significantly over the coming years, and a huge shift in control, operation and planning of distribution networks is going to be necessary if this generation is to be connected in a cost effective manner. Traditionally, distribution networks have been operated as passive networks with uni-directional ...

this study attempts to find if better performance in power play leads a team to victory in a twenty20 match. based on the methodology devised to do so, the study tries to measure the performance of both the teams during power play overs in terms of batting and bowling. the developed measure is called ‘prod’ which is a product of the difference of batting and bowling performance of the teams dur...

the microgrid concept provides attractive solutions for reliability enhancement of power distribution systems. normally, microgrids contain renewable-energy-based distributed generation (dg) units, which their output power varies with different environmental conditions. in addition, load demand usually changes with factors such as hourly and seasonal customer activities. hence, these issues hav...

This paper describes a stochastic “Random Chemistry” (RC) algorithm to identify multiple (n− k) contingencies that initiate large cascading failures in a simulated power system. The method requires only O(log(n)) simulations per contingency identified, which is orders of magnitude faster than random search of this combinatorial space. We applied the method to a model of cascading failure in a p...
