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 .

Smart Grid Technology

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 integration of highly permeable renewable energy to the grid at different levels (transmission, distribution and grid-connected), the volatility on both sides (source side and load side) leading to bidirectional power flow in the power grid complicates the control mechanism. In order to ensure the real-time power balance, energy exchange, higher energy utilization efficiency and stability maintenance in the electric power system, this paper proposes an integrated application of blockchain technology on energy routers at transmission and distribution networks with increased renewable energy penetration. This paper focuses on the safe and stable operation of a highly penetrated renewable energy grid-connected power system and its operation. It also demonstrates a blockchain-based negotiation model with weakly centralized scenarios for “source-network-load” collaborative scheduling operations; secondly, the QoS (quality of service) index of energy flow control and energy router node doubly-fed stability control model were designed. Further, it also introduces the MOPSO (multi-objective particle swarm optimization) algorithm for power output optimization of multienergy power generation; Thirdly, based on the blockchain underlying architecture and load prediction value constraints, this paper puts forward the optimization mechanism and control flow of autonomous energy coordination of b2u (bottom-up) between router nodes of transmission and distribution network based on blockchain.

Power transformers are one of the important equipment in the electric power system. Power transformers are devices with the largest investment in a transmission and distribution substations. Currently, the use of power transformers at Marunda substations on average has reached 80% of rated load. Then require maximum of cooling transformers, to restrain the rate of the winding and oil temperature rise. Result of the research were obtained with the addition of water cooling at power transformers can be reduce the heat due to the high ambient temperatures. The results showed a decrease in temperature of 3°C, so can be used to add transformers loading of 2,51 MW. While of water consumption was 2,052 m3 per day.

Thanks to the development of technology, the presence of electric vehicles (EVs) on the roads is no longer a purely theoretical issue. Also in Poland, electric cars are already visible on the streets, and charging stations (EVCS) are increasingly being installed near newly emerging buildings and housing estates. The article attempts to determine to what extent the use of electric cars will affect the demand for power and energy in the Polish electric power system (PEPS). The basis for PEPS modernization plans should be a detailed analysis of the technical adequacy of all its subsystems: generation, transmission and distribution, on the basis of which it will be possible to assess the potential impact of EVCS infrastructure operation on the Polish electric power system. This publication presents an example of such analysis for the distribution sub- sector, most exposed to potential negative interactions with the future, extensive infrastructure of EVCS.
