The goal this article is to provide the knowledge on the role smart meter technology in the smart grid. The commissioning of smart grid pilot projects for research and supporting them by Government of India shows the interest of future development. Smart meter definitely has a great role in smart grid and is considered as most important for future energy management... - Dr. Sarat Kumar Sahoo,  Vikram K

Solar photovoltaic (PV) and wind two important renewable energy sources reached grid parity in 2010. This means that these renewables no longer need subsidies or government support for their growth. India is a tropical country that is blessed with ample solar power reception (6 lakh GW). This article has rectified the flaw and propose a metering and tariff policy that would foster widespread growth of solar roof-top in a diverse democratic country such as India. - Vithal Kamat, Nivea Chauhan Harsh Bhatt Payal Bhadresa Akash Senta

This paper describes the use of advanced line current differential protection, to address conditions like CT saturation at only one-end during through fault conditions. It also describes an industry-unique three-terminal application of line current differential protection within Hindalco Industries Limited... - Raman Bajpai, Kaushik Tarafdar, Sthitaprajnyan Sharma

Series compensation increases the transmission capacity and improves the stability of a power system. Since transmission line itself consumes reactive power as it transmits the active power... - Rajesh Chourishi

Conventionally, grid connected photovoltaic energy conversion systems are composed of a DC-DC converter and an inverter. The DC-DC converter is controlled to track the maximum power point of the photovoltaic array and the inverter is controlled to produce current in such a way that the system current has low Total Harmonic Distortion (THD) and it is in phase with the utility voltage. The efficiency of the conventional system is low because the DC-DC converter and the inverter are connected in series. The purpose of this article is to design a photovoltaic generation system for connection in a three-phase system using only a DC/AC inverter... - Dr. L Ashok Kumar

KEC International has secured new turnkey order of Rs 1,496 crore in its Transmission & Distribution business in Bangladesh for design, supply and installation of 400 kV Meghnaghat – Madunaghat Double Circuit Transmission Line.

Smart energy grid indicates an energy network that allows a two-way communication between suppliers and consumers, while monitoring the network condition in real time i.e., electricity production, consumption and distribution... - Jayesh G Priolkar

This paper deals with the present state of energy technology and the prospects for its growth. The general aspects of this subject need to be known. To achieve this goal, it is important that the engineer studies the pertinent literature that gives him a new horizon and understanding of diversified connections between power engineering and different branches of economy, the biosphere, and a great variety of activities aimed at promoting technological progress... - C S Indulkar

'Assured and quality electric supply' is one of the core infrastructure elements of the smart city. The backbone to drive this objective is to implement an efficient and intelligent power distribution system. The trigger for an efficient power distribution network begins with the demand assessment. The methodology for arriving at the optimum demand assessment and planning of power distribution network for a smart city is deliberated in this article... - D Geethalakshmi, Fazlullah Syed

Electricity demands increase day by day causing imbalance in the present power grid system, which results in various problems like load shedding and unbalanced voltage, ultimately affecting consumers. To avoid all such situations, the only option is to meet increasing demand for electricity by generating more power. However, since we lack conventional natural resources, the use of renewables may perhaps be the only way out... - Amrita Tandon

With the increasing size and complexity of the transmission networks, the performance of the power systems decreases due to problems related with the load flow, power oscillations and voltage quality. Flexible AC Transmission (FACTS) offers effective schemes to meet these demands...  - Dr G D Kamalapur

Wireless sensors can play a key role in sensing the growth in energy demand and prompting actions to control this demand during peak hours. Intelligent electronic appliances fitted with sensors can communicate with the electric grid in real time to switch off or defer operation to cheaper off-peak hours, thus helping in energy balancing during peak loads... - Jayant Sinha

A T & C loss is nothing but the sum total of technical and commercial losses and shortage due to non-realisation of billed amount... - Robbin Pramanick

There is a need for information on the attempts of EHV transmission and experiences during installation. Sharing new design concepts, tower construction ideas, operation and maintenance aspects of these EHV lines will help in avoiding duplication of efforts... - Ravi Kant Kumar, Girish A Kulkarni

Micro-grids include low voltage distribution systems with distributed energy resources and controllable loads that can operate in medium voltage grid connected mode or in islanded mode. It provides environmental and economic benefits for end-user, customers, utilities and society. However, their implementation creates great technical challenges, such as the protection. Micro-grid system has bidirectional power flows, which make traditional fault insufficient. An algorithm combining of cumulative sum and power flow method is found to be simple and faster for detecting micro-grid faults in both modes of operation... - Vikrant J. Majarikar, K.S. Swarup

The power flows from power utilities to consumers whereas if wireless sensor networks are added, then the real time price information will also flow from base station to consumers. If the consumer is aware of price of power in peak times, then consumer will act accordingly and regulate his consumption as per price information sent to him. - Geeta Yadav

The type of underground cable to be used at a particular location is determined by the voltage at which it is re-quired to operate. Underground cables are classified and used at a particular location as per their voltage rating. - Munazama Ali

The grid collapse can cause half of the population to face darkness focusing a need of reliable well monitored supply system. Hybrid AC/DC microgrid can be the answer to resolve this problem of energy scarcity and uncertainity of supply – particularly for remote, sparsely geographically rural population... - Dr. Mrs. G. A.
