A review on industry challenges in smart grid implementation

Abstract: As the gap between supply and demand of electrical power is getting wider the continuous power supply is not possible for all at the same time. Existing power grid is not well suited for 21st century power flow from generation to end user. To focus on the challenges of 20th century grid like blackout, power discontinuity, Frequency variation, etc. the new concept of smart grid emerged. It is expected to be new industry platform. The aim of this paper is to recognize the challenges that smart grids are facing in implementation by industry. This paper presents critical issues on smart grid technologies mainly in terms of the technological challenges to the industry along with business, economic, regulation and standardization challenges. The main objective of this paper is to provide a coeval look at smart grid challenges and to discuss the research issues in this field which is still-open. It is expected that this paper will provide a better understanding of the technologies, advantages and the research challenges of the smart grid implementation and provoke interest among the researcher to further explore and evolve this promising research area.

Analyzing the Impact of Fog and Atmospheric Turbulence on the Deployment of Free-Space Optical Communication Links in India

Abstract: This paper aims to study the possibility of deployment of free-space optical communication (FSOC) links in India. We have focused on different locations of India for investigating the feasibility of the FSOC link, and it includes the coastal and inland locations, representing the major commercial areas of India. The atmospheric data related to daily visibilities and wind speeds, over 5 years, along with altitude of locations have been studied to calculate the scattering and turbulent losses. The losses due to scattering and turbulence are further added to find the total atmospheric losses for all locations. The atmospheric losses are maximum for the coastal location of Mumbai, and the inland location of Chandigarh has recorded minimum atmospheric losses. We have calculated maximum achievable link ranges for different locations mathematically by using the power link margin equation and atmospheric losses. Further, the results have revealed that the longest FSOC link of an optimal range of 3.24 km can be deployed in Chandigarh, while Mumbai has the shortest FSOC link of range 1.76 km under the average atmospheric conditions. Additionally, we have designed an FSOC system using Optisystem 13.0 software and analyzed the system performance for different locations of India by incorporating the atmospheric losses of different locations. Furthermore, we have verified the results of the mathematical and simulation model. The maximum achievable link ranges calculated by using the mathematical and simulation model have demonstrated close similarity with an average percentage error of 2.42% only.

On the rapidity distribution of nucleons participating in elliptical flow at intermediate energies

Abstract: The distribution of nucleons participating in elliptical flow is studied for the reactions of 79197Au + 79197Au, 60150Nd + 60150Nd, 50124Sn + 50124Sn, 4496Ru + 4496Ru, 3678Kr + 3678Kr, 2048Ca + 2048Ca and 2040Ca + 2040Ca using isospin-dependent quantum molecular dynamics (IQMD) model for various centrality ranges and over the wide range of intermediate energy. Our findings reveal that the sigma (width) of rapidity distribution obtained varies with mass of colliding system at a given energy. The peak of rapidity distribution decreases with decrease in the mass of colliding nuclei. Transition energy as well as width of rapidity distribution depends on the mass of fragment for a given centrality. Influence of isospin dependent symmetry energy and nucleon–nucleon cross-section can be studied using rapidity distribution. Second transition energy depends on the mass of the fragment. Rotational phenomenon of nucleons can be observed for nucleons participating in elliptical flow.
