In this paper a transformerless Static Synchronous Series Compensator (SSSC) to increase the power capacity of a 230 kV transmission line is proposed. In order to eliminate the transformer, a 15-level cascade H Bridge (CHB) inverter is employed within the proposed compensator structure to inject reactive power to the transmission line. The theory of instantaneous p-q power using in the compensa...

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...

Accurate Measuring of poverty and its distribution in various areas, in addition to being crucial for cognitive purposes, could have different policy implications and affect policy assessments. The Household expenditures criteria is typically used to measure poverty, and poverty is often assessed using a poverty line and alternative indices. A major difficulty associated with this method is, ho...

This paper presents a new system configuration for a large-scale Photovoltaic (PV) power system with multi-line transmission/distribution networks. A PV power plant is reconfigured in a way that two adjacent power system networks/ feeders can be interconnected. The inverter modules in a PV power plant are configured such that the system is represented as a back to back inverter connected multi-...

Efficient operation of distribution grids in the smartgrid era is hindered by the limited presence of real-time nodal and line meters. In particular, this prevents easy estimation of grid topology and associated line parameters that are necessary for control and optimization efforts in the grid. This paper studies the problems of topology and parameter estimation in the limited observability re...

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...

Phase and cable identification is a challenging issue. Power-line communication technology is applied to identify cable and phase of power distribution systems. Power cable circuits have only a limited ability to carry higher frequencies. Typically transformers prevent propagating the higher frequency carrier signal. The proposed method uses the limited propagation ability to identify the cable...

Electric power is the most essential raw material impacting the bottom line of quality production economically on a commercial scale. It can‟t typically be stored like other commodities and is essentially required with continuous flow all the time. Electric power can be visualized as the epitome of „just in time‟ philosophy used like the components delivered to a production line by a trusted an...
