Study of Economic Performance of India due to Trade with SAARC Countries
The paper empirically examines the trade led growth paradigm for India with respect to SAARC countries for the period 1990-2014. The paper uses the co-integration model to test the causal relationship between trade and output growth. Granger causality test is applied for the period 1994-2015 to examine the nature of relationship between variables under study. The results indicate absence of long term relationship between India’s GDP growth and trade among SAARC nations, thereby giving way to the existence of short term relationship. Granger causality revealed unidirectional nature of causality from exports to GDP and Imports to GDP for Nepal, Pakistan and Sri Lanka, GDP to export for Maldives, GDP to import for Bangladesh, Import to export for Bhutan and Sri Lanka and export to import for Pakistan
Performance of Top Management Institutes of India
In this paper we have examined to examine the efficiency of top 50 Indian B-Schools. Study of management institutes is very useful as they are preparing professionally qualified personnel in the area of management. To achieve these objectives, the management institutes need various parameters like highly qualified, motivated and committed faculty members, talented students with adequate background and a vision for growth. The data envelopment analysis used to identify management institutions which are able to utilize their resources in a most efficient way. This model is used to evaluate the relative efficiency of a group of decision-making units (DMUs) in their use of multiple inputs to produce multiple outputs where the form of production is neither known nor specified as in the case of parametric approach. The paper investigates management institutes from various points of stakeholders. Technical efficiencies are identified with failures to achieve best possible output levels and/or usage of excessive amounts of inputs. The findings in the study of B-Schools may be useful in converting the inputs to outputs
Integration of embedded generation in local grid using STATCOM
The renewable sources of energy are being connected to the local distribution system/local grid leading to embedded generation. As these sources are intermittent in nature, they impose technical challenges in the power system operation which include power quality related problems of local grid. The performance of the system has to be evaluated while connecting these sources to the local distribution system/micro grid. In this paper, the application of STATCOM-based power quality conditioner for improving the performance of wind driven induction generator embedded to the local grid have been discussed. The modelling, control and analysis of the proposed STATCOM-based power quality conditioner have been given. The MATLAB Simulink-based system model has been used for the performance evaluation while connection of wind-driven induction generator to the local grid, its variable speed operation and unbalanced supply system. The STATCOM-based power quality conditioner has been found effective for the power quality improvement of the local grid.power quality conditioners; wind energy conversion systems; induction generators; voltage sag; voltage unbalance; voltage flicker; voltage harmonics; static synchronous compensator; STATCOM; wind power; simulation; modelling; performance evaluation; variable speed; unbalanced supply; power quality improvement; local grid.

Power quality evaluation in deregulated power system using matrix method
Power quality has emerged as a challenging area in the context of deregulation, wherein electricity distribution buyers and sellers carry out mutually agreed-upon exchanges. A market for active power and reactive power is installed in many places as a result of a deregulation process. However, the power-quality-related market is in the developing stage. For a given site, the power quality attributes have individual indices which have to be combined to give a suitability index so that the performance of the supply system may be evaluated at the point of common coupling. In this paper, a new technique based on the matrix method and permanents is proposed to quantify the power quality of a site. The proposed algorithm method is explained and illustrated with a sample problem on site evaluation and ranking.power quality; voltage sag; voltage swell; harmonics; flicker; unbalance; suitability index; permanent; matrix method; deregulated power systems; electricity distribution; deregulation.
