Message
Silicon Institute of Technology through its Department of Electrical and Electronics Engineering is organizing a National Workshop on Emerging Technologies in Electrical Power Engineering (NWET-2015) with focus on Grid Integrated Renewable Energy Systems: Design Consideration & Challenges.
As India prospers, its prosperity has to be backed by making more electrical energy available to common citizen. So every time we should look for different types of renewable energy sources as solar, wind and hydro. I am sure that discussion during the workshop will show new ways to generate power from different renewable sources, which improves our power scarcity. This will give us some breathing space before new and renewable energy sources become commercially viable. I wish the NWET2015 a great success.

Message
In this era of knowledge, when technical institutions are clamoring to churn out ready-to-be-absorbed engineers by the industry, Silicon is making strides towards evolving directions for the growth and dissemination of technical knowledge for the purpose of research and innovation.
Nevertheless, industry altogether cannot be ignored if we are to build a just and equitable society around us and contribute to the growth our nation.
It is with these clear thoughts the department of Electrical & Electronics Engineering has been organizing National Workshop on Emerging Technologies (NWET-2015) for the past eight years. This year the focus is on "Grid Integrated Renewable Energy Systems: Design Consideration & Challenges" which is the need of the hour.
I congratulate the organizing team for their consistency in doing this workshop. I welcome all participants to this workshop. Wish you best of luck in your endeavor.
Thank You

This workshop is an annual event in Silicon Institute of Technology, dedicated to improve Industry-Academia interaction. Organizations like PRDCL Bangalore, CPRI Bangalore, OPTCL Odisha, Nalco Odisha, IIT Bhubaneswar, and NIT Rourkela have extended cooperation for last seven years. This year the solar energy Society of India and the PES chapter of India Council IEEE have come forward with technical sponsorship.
The subject of the workshop is Renewable Energy and its integrated operation with the grid. We do not discuss the viability issues of solar and wind energy any more. The two technologies are not only going to stay, but are going to play a major role in the energy security of the globe. An accelerated capacity addition and grid acceptance is the need of the hour and our industry and academia must join hands so that society gets the best out of the renewable sources.
I shall consider the workshop successful if every participant contributes to this objective and drives the mission forward.
Prof. A. K. Tripathy Former DG, CPRI
Convener, NWET-2015
Message
Recently the central government has set a target of providing 24x7 power to all households by 2019. While the National Action Plan on Climate Change (NAPCO) aims at increasing the share of energy from renewable sources from 5% to 15% of the total consumption by 2020, the recently introduced Electricity Amendment Bill 2014, too, proposes to make it
mandatory for any company establishing lignite and coal-based thermal power plants, to generate renewable energy. Hitherto, the energy from renewable sources was considered suitable for remote usage, i.e., these sources were used in standalone mode catering to the public deprived of electricity. With increased generation and access to all households, these Renewable Sources are now required to be synchronised to the Grid System. However, the nature of RE generation poses challenges and calls for advanced technological methods in this perspective.
I am happy that the Silicon Institute of Technology is organising a National Workshop on the subject and hope the Seminar will come up with positive and meaningful outcomes.
I wish the Seminar all success.

Energy conservation. NWET-2012 discussed on modern power distribution. NWET 2013 focused on Energy policies and Regulations. NWET-2014 was
focused on modern grid management. NWET- 2015 will be held at Silicon
Institute of Technology, Bhubaneswar from 19th to 21st February, 2015 and will be focusing on issues related to Grid Integrated Renewable Energy
System: Design Consideration & Challenges.
Of late there has been phenomenal growth in Solar and Wind Power
Generation not only in India but globally. There has been an increased
interest in research, product development and establishment of manufacturing and testing facilities. The cost of renewable energy
particularly the solar energy has recorded a sharp fall and is now comparable with cost of conventional generation. The world attention has
gone in favor of distributed energy generation because of lower capital
investment and better flexibility. The attractive feature of renewable energy is that it is green and non–polluting. However two areas of concern
are intermittence of generation & difficulty faced in seamless integration with the grid. Technology development over recent years has been able
to largely address these issues.
The objective of the workshop is to bring to focus areas of technology development that aim to take renewable energy into the main stream.
Policy preferences in favor of renewable energy that would accelerate this
process shall also be discussed. The workshop would be largely addressed by researchers and professionals in the field and shall be tailor made for
utilities, industries, students and users of electricity.

Abstract:
Wind Energy is a major component of Renewable Energy (RE) being vigorously
exploited globally for power generation to reduce dependence on polluting fossil
fuels and emissions. India is 5th in installed wind capacity. Unit sizes have increased
from about 50 kW during 1980s to beyond 5 MW today for both on shore and off shore
installations. Accordingly tower height and blade dia. have increased manifold
posing great technical challenges. Both vertical and horizontal axis wind turbines are
used through bulk are of latter type.
Normally speed of turbine is stepped up through gear box to suit the generator which
feeds converted power to the grid via a transformer. For long, bulk of the generators
was near constant speed squirrel cage induction generators (SCIG). But recent trend
is to go for variable speed systems such as doubly fed induction generators (DFIG)
and permanent magnet synchronous generators (PMSG) towards maximum power
point tracking (MPPT). The talk describes state of art of WES and future trends.

Abstract:
Real Time Monitoring and control of Power Systems is very important for reliable and secure operation of Power Systems. The ever increasing power demand and expansion in power systems as well as ever increasing penetration of the renewable energy integration has made the power system operation quite complex now than the earlier days and real time monitoring and control have now become very crucial for reliable, economic and secure power system operation and control.
The advancements in hardware and software technologies are bringing significant changes in the operation practices of power systems and real time monitoring of power system has also been tremendously benefitted with these
advancements like implementation of Phasor Measurement Units (PMUs). PMU technology has provided the capability to get the time stamped measurements with time synchronized through GPS. Therefore, PMU technology has also provided the capabilities of δ measurement between system buses in an appropriate way. This gives much better capability for real time operation and control for power systemsand improves results for the energy management systems applications.

Abstract:
In last couple of years in India, we are witnessing the change. The talk about solar energy was very very rare before a decade. Later, the solar thermal heating gentally stepped in. Then comes solar photo-voltaic. The capacity installation 'measure' took quiet time to change from Watt to Kilowatt to MegaWatt. Now, Megawatt has become a basis measure in this industry, when we talk about the targets earmarked for installation in SOLAR INDUSTRY in INDIA.
Goverment of India is leading the front followed by many state Government. Encouragement in this sector is amazing. The Manufacturer, developers and Finance agency are getting a confidence about the solar energy sector in India. The youth of today in our country is lucky, if they are getting attracted towards this sector. The OPPORTUNITIEs in the sector are entering new doors on each day. The youths have started and will do wonders in the sector for the betterment of life of every citizen of this country and will innovate, install and execute innovative technology and applications. To put this otherwise going waste and abundant energy source to work and make our day as well as night “illuminated" in all part of life

Abstract:
Global Energy security is a major concern. Energy consumption is increasing at the
rate of 6 to 7% annually and the conventional sources of energy are getting
exhausted too fast. This has made it necessary to look for alternative sources of
energy. Many of the known sources of green energy have made their entry in the
market, many others are in pilot stages waiting to be commercialized and some of
them are futuristic but hold a lot of promise. Almost every Nation is in the lookout for
alternative sources which it can harvest. India is no exception.
Other than wind, solar, bio fuels and mini and micro hydro resources, the other
promising resources are , wave and Tidal energy, Geothermal energy, Coal bed
methane, Gas hydrates, Wireless power, Fuel cells, compressed air etc. Some of these
will be at locations where transportation of power to load centre shall be a major
issue. Some others could be very near to the load but in smaller sizes. Integration of
these to the existing grid shall be tricky.
The lecture covers the present research interests and challenges in finding alternate
sources of energy.

Abstract:
In recent years, Renewable energy has become an important part of electrical
generation in many countries and its importance is continuing to increase. The amount of
Renewable generation is growing rapidly and wind& Solar farms are growing in size and
complexity. The location of a RE plants is selected primarily based on their potential for
maximum energy extraction (and of course, favorable economic and environmental
conditions). However these sites often coincide with relatively remote parts of the power
system and their generation availability with respect to the demand is an issue.
In recent days, curtailment in wind and solar generation were observed in several
systems. It is reported that the curtailment is higher during the transitional phase of
planned, infrastructural, operational or institutional changes in the grid. The main reasons
attributed for the curtailment are transmission congestion, minimum operating level of
thermal power plants, requirement of downward reserve, minimum operating level of
hydro plants due to environmental, recreational or irrigation constraints, to maintain
frequency requirements and stability issues. In distribution system curtailment is initiated
to avoid power transfer from distribution system to transmission system.
It is noted that the curtailments in wind generation is observed in Ireland, Italy, Spain,
Denmark, United States and Japan. The curtailment in Hydro Quebec in Canada and
Sweden is due to network constraints/technical faults. In most of the systems, the
curtailment occurs during periods of low load and high wind. The curtailment issues are
further complicated with the non-dispatchable combined heat and power (CHP) plants.
In Portugal, the legislation restricts curtailment of renewable generation except in the
case of technical problem. Hence Portuguese TSO resorts to the practice of transmitting
the excess generation to Spain at zero value.
Considering their importance and harness the naturally available energy sources, there is
need to have Renewable Energy Management System to be in place to manage these
resources and at the same time making sure the stability and reliability of power system is
secure. Technological breakthrough has made the operation of RE generations as a
virtual power plant mimicking the characteristics of the modern conventional generation
by management & control of these resources. The success of large RE penetration lies in
creating additional tools and controls in managing these resources to have secure power

Abstract:
Penetration of distributed generations (DGs) has gained momentum owing to market deregulation and environmental concerns. Despite numerous benefits of micro-grid with DG integration including the ability to operate in islanded mode, the protection
challenges becomes a serious concern, where performance of the convectional relays degrade and further cease to operate. The fault current varies with the operating mode of micro-grid (grid connected and islanded). In such scenario the fault protection relay with fixed setting may fails. The protection relay faces serious challenges as the micro-grid operates with different types of DGs including synchronous, induction and inverter based DGs. The fault current magnitude varies significantly depending upon the type of DG contributing to the fault. It is observed that inverter based DGs contributes twice the rated current of the inverter to the fault whereas synchronous and Doubly Fed Induction Generator (DFIG) DGs can contribute to fault 4 to 10 times greater than the inverter based DGs. The operating conditions and network topology of the micro-grid may change regularly so as to provide a quality and reliable power to the consumers. Under such varied operating conditions, there will be wide variations in fault current seen by the relay for a fault occurring at a specific location in the micro-grid. Thus, the relays placed at both ends of the lines must be selective and reliable as there is bidirectional power
flow due to presence of DGs in the micro-grid. This talk focuses on data-mining model based intelligent micro-grid protection scheme for micro-grids.

Abstract:
Organic -waste from agriculture and domestic management are major challenge areas throughout the world. Without an effective and efficient waste management program, the waste generated from various human activities, can result in health hazards and have a negative impact on the environment. Understanding the waste generated, the availability of resources, and the environmental conditions of a particular society are important to developing an appropriate waste-management system. However, a lack of awareness, technical knowledge, legislation, policies and strategies are major issues for waste management in India. The government has to strengthen their efforts to control the rapid growth rate of waste generation and to allocate adequate resources for waste management. Green Productivity (GP)
measures including reduction, recycling, reuse, and recovery should be enhanced immediately. Biogas production through anaerobic digestion of biomass, including the organic fraction of waste materials and residues, is a particularly promising choice and experiences increasing interest worldwide. It does not only supply a clean and versatile energy carrier, but is well suited to contribute towards appropriate waste management schemes in urban areas and in agriculture. While there is an obvious need to minimize the generation of wastes and to reuse and recycle them, the technologies for recovery of energy from wastes can play a vital role in mitigating the problems. Besides recovery of substantial energy, these technologies can lead to a substantial reduction in the overall waste quantities requiring final disposal, which can be better managed for safe disposal in a controlled manner while meeting the pollution control standards.

Abstract:
Microgrids, which are localized grids that can disconnect from the traditional grid to operate autonomously and help mitigate grid disturbances to strengthen grid resilience, can play an important role in transforming the nation’s electric grid. Microgrids can strengthen grid resilience and help mitigate grid disturbances because they are able to continue operating while the main grid is down, and they can
function as a grid resource for faster system response and recovery. Microgrids also support a flexible and efficient electric grid, by enabling the integration of growing deployments of renewable sources of energy such as solar and wind and distributed energy resources such as combined heat and power, energy storage, and demand response. In addition, the use of local sources of energy to serve local loads helps reduce energy losses in transmission and distribution, further increasing efficiency of the electric delivery system. Renewable Energy Integration focuses on incorporating renewable energy, distributed generation, energy storage, thermally activated technologies, and demand response into the electric distribution and transmission system. A systems approach is being used to conduct integration development and demonstrations to address technical, economic, regulatory, and institutional barriers for using renewable and distributed systems. In addition to fully addressing operational issues, the integration also establishes viable business models for incorporating these technologies into capacity planning, grid operations, and demand-side management.
