The term "smart grid" refers to the transformation of the traditional electric power grid into a modern grid. Modernization of the present electric power system is an important step to implement the Smart Grid technology. The structure of the existing power sector in Bangladesh is almost a hundred years old. Due to which the power sector of Bangladesh facing huge power wastage. A Smart Grid also ensures the efficient transmission and distribution of electric power. This paper gives a brief description of Smart Grid, the latest trends, challenges, prospects, cost analysis of smart grid equipment, and its facility. The spotlight of this paper is to implement the Smart Grid's perspective to Bangladesh. That’s included to have new distributed generation technology, smart meter, a pilot project, etc. Also, the main objective of this paper is the comprehensive development of transmission and distribution loss reduction, which will be saving a big amount of capital every year. And that will play a huge role in the economy of Bangladesh to move forward in global progress.

With the development of smart grid technology, more and more intelligent devices and applications are accessed into the electric power system, which put forward higher requirements on network communication and monitoring. Power distribution and electricity utilization network directly facing the ultimate power users, is the embodiment of the smart grid in customer aspect. Flexible, efficient and reliable communication network will greatly improve the user experience. The network is commonly referred to as power communication access network. In order to improve the performance of service bearing network, a novel service driven modeling method for requirement analysis is proposed. Furthermore, the paper offers some recommendations for network design.

Recently, there have been significant technological approaches for the bulk power grid. The customer demand is associated with conventional grid coupled large central generating stations through a high voltage transmission to a distribution system. Urban transmission systems are consistently progressing to meet the increasing needs for power and to replace old-pattern generation with native renewable generation and power provisions from outward green energy resources. Power grid is undergoing remarkable modernization towards advanced consistency, greater efficiency, and less cost by the incorporation of renewable energy and developed control technology. Quick developing nature of grid, consumer needs, and industrial invention situates substation modernization at the leading of grid transformation. Smart grid is essential to accomplish all the fastest technological reformations occurring in generation, transmission and distribution (T&D) of electric power, with growing application of sensors, computers and communications. In this study the recent trend and application of electric power grid is briefly enunciated.

An integrated Smart Grid system has been developed for matching the production and consumption of electric power based on a prediction of changes in the battery capacity. Advanced decisions on the change in power transmission capacity have made it possible to regulate voltage in the distribution system by maintaining the power factor of the photoelectric charging station. Voltages at the input to the hybrid inverter and in the distribution system were measured to assess their ratio. Comprehensive mathematical and logical modeling of the photoelectric charging station was performed based on the mathematical substantiation of architecture and operation maintenance. A dynamic subsystem including such components as mains, a photoelectric module, a hybrid inverter, batteries, a two-way counter Smart Meter and a charger formed the basis of the proposed technological system. Time constants and coefficients of mathematical models of dynamics in terms of estimation of changes in the battery capacity and power factor of the photoelectric charging station were determined. A functional estimate of changes in the battery capacity and power factor of the photoelectric charging station was obtained. Maintenance of voltage in the distribution system was realized based on resulting operation data to estimate a change in the battery capacity. Advanced decision-making has made it possible to raise the power factor of the photoelectric charging station up to 40 % due to matching the electric power production and consumption. Maintenance of operation of the photoelectric charging station using the developed Smart Grid technology has enabled prevention of peak loading of the power system due to a 20 % reduction of power consumption from the network.

Ruri Diana Putranti, Iman Setiono, in paper calculation of energy losses of Tambak Lorok - 03 feeder as one of the pilot project program REVASS (revenue assurance) in energy reconciliation program of PT . PLN (persero) semarang area explain that in an electric power system there is a factor called the loss factor or energy depletion . This shrinkage can be found in various places on the electricity network , from generation, transmission and distribution of both to consumers . The release of energy or commonly referred to as shrinkage , the harm to the company for commercial and service in large and small quantities . Pond feeder Lorok - 03 is one of the feeders are thought to have a large enough energy depletion . This feeder is in the working area of ​​PT . PLN Rayon East Semarang and is a feeder into the pilot established REVASS ( Revenue Assurance ) PT . PLN Semarang area . Based on mathematical calculations that have been carried out in February 2013 the amount of power loss in the feeder is 2,316,319 KWH , while in the month of March 2013 is 4,765,637 KWH and in April 2013 amounted to 18,809,238 KWH . The amount of power loss raises the average monthly percentage losses in the feeder that is between 10-20 % . This of course lead to a loss for the company , especially on the commercial side that is the size of the company to the customer's receivables . Therefore , a program in which reconciliation is REVASS this project , is one attempt to get the suitability amount of energy from the power sent to the power received at the customer . Keywords : Electric Power System , Network Distribution , Energy Losses , Reconciliation of Energy

In this paper, we integrate technological, institutional, and financial approaches towards expansion of the smart grid technology. We turn to China as the major producer and consumer of energy with an increasing focus on renewables. China’s electricity market has experienced a number of reforms while trying to address the economic and environmental challenges. In order to identify the basic requirements for the Chinese power sector, we look into the underlying trends of the energy mix, regulatory policies, and financial flows. Understanding these facets allows one to suggest directions for the further development of the Chinese power sector in the light of the smart grid concept. Indeed, the smart grid concept has no strict definition and, therefore, requires simultaneous consideration of multiple factors. The analysis shows that ensuring smooth transfer of electricity across the regions is a quintessential condition for smart grid development and the promotion of renewable energy in China. As the role of the state-owned enterprises still remains the most important one in the sector, private initiatives should be supported. Therefore, financial incentives are needed to guide the shifts in the energy mix and maintain efficient energy generation and consumption in China.
