Surge Protection Devices Paper (SPD) SM54Subhash Mahla
This document summarizes research on surge protection devices called superconducting fault current limiters (SFCLs). SFCLs can limit fault currents faster than conventional circuit breakers. There are three main types of SFCLs - resistive, inductive, and bridge-type. The document focuses on resistive SFCLs, which function by turning superconducting elements resistive during faults to absorb fault current energy. Resistive SFCLs can be installed in transformer circuits, feeder circuits, or bus sections to protect downstream equipment from excessive fault currents. Simulation results showed resistive SFCLs can effectively limit faults within one cycle to improve power system stability.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
Low power architecture of logic gates using adiabatic techniquesnooriasukmaningtyas
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

I. INTRODUCTION
The ”smart grid” is a term used to describe the rapid
infrastructure replacement of the electrical wiring system in
the United States. When the advanced system is completely
implemented, it will allow for communication features across
the grids that are not currently available–hence the term
”smart”[2]. A smart grid is simply an advanced electrical
distribution system that has the capability to balance electrical
loads from diverse, and often intermittent, alternative energy
generation sources. One key component of the smart grid is
the capacity to store electrical energy.
Today’s power systems are designed to support large gener-
ation plants that serve faraway consumers via a transmission
and distribution system that is essentially one-way. But the
grid of the future will necessarily be a two-way system where
power generated by a multitude of small, distributed sources in
addition to large plants flows across a grid based on a network
rather than a hierarchical structure [3].et [1].
Fig. 1: The Shift between today’s Power system (left) and
Realized Smart Grid [3]
The basic idea of Smart grids is about information and
control as much as power management. Much of the infor-
mation is sent over the power lines using broadband over
power Lines (BPL), which superimpose information on top of
the Electrical power. This information can reroute electricity
around problem spots until the problem is fixed, and adjust
power levels to match demands. Both power suppliers and
power consumers can be accommodated by smart grids. Wind
and solar power can add to the grid, and consumers can
be charged higher rates during peak consumption hours and
lower rates when consumption is low. Smart grids can even
adjust for reduced output from solar cells on cloudy days and
from wind turbines on still days, in addition to the increased
demands from air conditioners on hot days. Smart grids can
also quickly respond to natural failures Disaster Avoidance
or terrorist attacks by rerouteing around problems or closing
down the network entirely.
II. SMART GRID DRIVERS
The forces now driving the development of the smart grid
are as varied as they are influential. Environmental concerns
are increasing around the globe, and that is driving the
expansion of renewable energy on a larger scale than ever
before. The widespread addition of wind, solar and other
renewable presents operational challenges due to those sources
intermittent nature. A grid that can handle a generation mix
with a high percentage of renewable, therefore, will become a
necessity for those technologies to realize their full potential
[6]
III. STATUS OF SMART GRID
The smart grid is more than any one technology, and the
benefits of making it a reality extend far beyond the power
system itself. The transition from the grid we know today
to the grid of tomorrow will be as profound as all of the
advances in power systems over the last hundred years, but
it will take place in a fraction of that time. It will require a
new level of cooperation between industry players, advocacy
groups, the public and especially the regulatory bodies that
have such immediate influence over the direction the process
will take. In the end, though, a fully realized smart grid will
benefit all stakeholders [3].
IV. SMART GRID TECHNOLOGY
Renewable energy systems (RESs) cannot directly replace
the existing electric energy grid technologies. The latter are far
2. 2
too well established to abandon, while the new technologies
are not sufficiently developed to meet the total energy demand.
Therefore, it is sensible to gradually infuse renewable energy
sources into existing grids and transform the system over time
[5].
Fig. 2: Intelligent Energy Conversion nodes [1]
Fig. 3: Complex Smart Grid technology Market [6]
Power system based on smart-grid technologies, with power
electronic building blocks (PEBBs) and With the development
of smart grid technology, the intelligent meters will be likely to
control home appliances, when users can adopt more sensible
strategies to reduce the cost of electricity during the high
electricity price. So peak load shifting can be achieved, and
the system will tend to be more economic, intelligent and
environmental friendly [1].
V. MODERN HARDWARE AND CONTROL FOR SMART
GRID
A smart information network the energy internet for the
electric grid is seen as necessary to manage and automate this
new world.
Sometimes have been forecasted within regular intervals
(weekly, monthly or yearly). Anyway, these non real-time
forecasts have their drawbacks and may not supplying correct
information when any of these events occurred[1]:
1) Sudden failure of any of the power sources.
2) Unexpected increase or decrease of power demand
within a short time frame.

advanced distribution systems [1]
VI. SMART GRID TECHNOLOGY AND APPLICATION
Smart grid concepts encompass a wide range of technolo-
gies and applications. We describe a few below that are
currently in practice with the caveat that, at this early stage in
the development of smart grids, the role of control, especially
advanced control, is limited [6]:
1) Advanced metering infrastructure (AMI) is a vision for
two-way meter/utility communication. Two fundamental
elements of AMI have been implemented. First, auto-
matic meter reading (AMR) systems provide an initial
step toward lowering the costs of data gathering through
use of real-time metering information. Second, meter
data management (MDM) provides a single point of
integration for the full range of meter data. It enables
leveraging of that data to automate business processes
in real time and sharing of the data with key business
and operational applications to improve efficiency and
support decision making across the enterprise.
2) Distribution management system (DMS) software math-
ematically models the electric distribution network and
predicts the impact of outages, transmission, generation,
voltage/frequency variation, and more. It helps reduce
capital investment by showing how to better utilize
existing assets, by enabling peak shaving via demand
response (DR), and by improving network reliability.
3) Geographic information system (GIS) technology is
specifically designed for the utility industry to model,
design, and manage their critical infrastructure. By inte-
grating utility data and geographical maps, GIS provides
a graphical view of the infrastructure that supports cost
reduction through simplified planning.
VII. SMART GRID PROBLEM
Implementing a smart grid power system has considerable
implications for personal privacy because the grid has the
3. 3
ability to control power access. Security experts believe that
this technology may allow someone other than the customer
to control the power supply. Some problems explained as [1]:
A. Privacy Problems
Security experts believe that smart grid technology may
enable some people to get control of the power supply.
Communication between utilities and the meters at residential
homes and businesses increases the chance of someone gaining
control over the power supply of a single building or an entire
neighbourhood.
B. Grid Volatility
Smart Grid network has much intelligence at its edges;
that is, at the entry point and at the end user’s meter. But
the grid has insufficient intelligence in the middle, governing
the switching functions. This lack of integrated development
makes the grid a volatile network. Engineering resources
have been poured into power generation and consumer energy
consumption, which are the edges of the network. However, if
too many nodes are added to the network before developing
the software intelligence to control it, the conditions will lead
to a volatile smart grid.
VIII. FUTURE SCOPE
The electric grid is unique in that electrical supply and
demand must remain tightly balanced at all times, since for
most of the history of the electric grid there has been no
commercial solution for large-scale storage of electricity to
compensate for any excess or shortfall in power.
The objective of transforming the current power grid into a
smart grid is to provide reliable, high-quality electric power to
digital societies in an environmentally friendly and sustainable
way. This objective will be achieved through the applica-
tion of a combination of existing and emerging technologies
for energy efficiency, renewable energy integration, demand
response, wide-area monitoring and control, self healing,
HVDC, flexible AC transmission systems (FACTS).
IX. CONCLUSION
Smart Grids are most comprehensive technology during
recent years and it has been grown rapidly because of its
benefits. It has many features and the transition to a fully
implemented smart grid brings a host of benefits in an often
symbiotic relationship:
GRID OPERATORS will enjoy a quantum improvement in
monitoring and control capabilities that will in turn enable
them to deliver a higher level of system reliability even in the
face of ever-growing demand.
UTILITIES will experience lower distribution losses, deferred
capital expenditures and reduced maintenance costs.
CONSUMERS will gain greater control over their energy
costs, including generating their own power, while realizing
the benefits of a more reliable grid.
THE ENVIRONMENT will benefit from reductions in peak
demand, the proliferation of renewable power sources, and
a corresponding reduction in emissions of CO2 as well as
pollutants such as mercury. Smart grid enabled distribution
could reduce electrical energy consumption by 5-10%, carbon
dioxide emissions by 13-25%, and the cost of power-related
disturbances to business by 87%. (Source: The Electric Power
Research Institute). Smart grid enabled energy management
systems have proven in pilots to be able to reduce electricity
usage by 1015%, and up to 43% of critical peak loads. (Source:
The Brattle Group, SMUD and PNNL.) The Smart Grid vision
generally describes a power system that is more intelligent,
more decentralized and resilient, more controllable, and better
protected than todays grid.
