Case Studies in Solving Modern
Electrical Engineering Challenges
Like engineers in every major discipline, electrical engineers
are facing mathematical challenges like never before.
Today there is a greater emphasis than ever on
issues such as:
• Sustainability – obtaining clean, reliable sources of
energy that satisfy geopolitical demands
• Efficiency – as human demands for electricity
increase and evolve at different paces
• Smart technology – as consumers demand greater
efficiency, control and customization
For electrical engineers, smarter systems that are
more efficient and meet higher expectations for
cleaner energy – and the complex mathematics that
they require – are at the core of meeting these sophisticated, modern challenges. The need to provide
sustainable, efficient and smart energy solutions
has never been more critical – and difficult. Electrical engineers are facing unprecedented pressure to
tackle some of the most cutting-edge problems in the
world. The world is experiencing a rapid transformation where people are demanding greater access to
renewable sources of energy, and where technology
provides solutions before the consumer realizes they
have a problem.
When we look at the engineering calculations that can
solve these issues, we often find that they are complex
and difficult to manage. It is no longer sufficient to
have engineering calculations, an organization’s intellectual property, locked away in spreadsheets and
traditional engineering notebooks.

Andasol 1–3: A Case Study in Storing
Energy from the Sun
Economic and political factors are putting pressure
on electrical engineers to make renewable energy
sources viable alternatives to fossil fuels. Clean
energy, like that generated by the wind or the sun, can
reduce air pollution, preserve natural habitats, reduce
the need for nuclear power, and help nations become
more energy independent.
There are now three operational Andasol plants, each
with a gross electricity output of 50 megawatts , and
producing about 180 gigawatt-hours per year . Each
collector has a surface of 51 hectares (5.5 million sq.
ft. or approximately 125 acres) and occupies about 200
hectares (roughly 500 acres) of land.
Andasol’s thermal storage system absorbs part of
the heat produced in the solar field during the day and
stores it in a mixture of sodium nitrate (60 percent)
and potassium nitrate (40 percent). A full thermal reservoir holds 1,010 MW·h of heat; this is enough to run
a turbine for about 7.5 hours at full-load when direct
sunlight is not available.
While there are additional expenses involved in setting
up the salt storage system, these costs are balanced
out by the additional hours of energy production.
Electricity from the Andasol plants costs about the
Electricity can be easily generated from the sun while
it’s beating down on photovoltaic and solar-thermal
panels, but engineers have struggled to find ways
to store that energy when night falls or storm
clouds roll in.
The process of using Molten Salts, however, is now
making it possible keep solar energy farms producing energy 24/7. Salt’s high melting point, plus the fact
that it doesn’t turn to vapor until it gets much hotter,
means that it can be used to store the sun’s energy
as heat.
Andasol 1, which went online near Granada, Spain in
2008, was the first commercial power plant to use
parabolic trough solar-thermal technology. The Andasol Plant was developed by Solar Millenium, AG, a
German solar company. According to Sven Moormann,
a spokesman for Solar Millennium, “The hours of production are nearly double [those of a solar-thermal]
power plant without storage.”
Economic and political factors are putting pressure on electrical
engineers to make renewable energy sources viable alternatives
to fossil fuels.

Impact Assessment of Plug-in Hybrid Vehicles:
A Case Study in Power Supply and Demand
While some engineers work to generate electricity
from new sources, others are studying the impact of
increased electricity demand. Researchers from the
Pacific Northwest National Laboratory, for example,
have been exploring the potential impact an emerging
fleet of Plug-in Hybrid Electric Vehicles (PHEV) will
have on power systems across the country.
Load flow estimates, overflow probabilities, average
capacity measurements and other calculations all
helped these engineers address two key questions in
a detailed power grid analysis:
• What are the impacts of a plausible penetration
of PHEVs on the electricity production cost at a
regional level?
• What are the impacts on CO2 intensity at a regional
level for a set of selected charging strategies?
peratures, and concentrating sunlight onto a single
tower to increase the temperature of the salts. Technology for storing solar energy using molten salts and
converting that stored energy to usable electricity
revolves around critical calculations for heat transfer, thermal analysis, and the conversion of melted
salt to supersteam. The molten salt mixtures can
vary, and typically are comprised of sodium nitrate
and potassium nitrate, although calcium nitrate can
also be included. Constituting the optimal salt mixture requires extensive calculations using the physical
properties of each salt and the ratios of the salts in the
mixture. Calculation software is often used for this
level of engineering optimization as it facilitates the
calculation and analysis process tremendously.
According to industry estimates, 80 percent of automotive
innovation in the premium segment comes from the electronics.

4. White Paper
The researchers assumed a year 2030 scenario with
37 million PHEVs on the road, where each vehicle
would demand enough energy to travel about 33
miles (53 km) per day. When assessing the energy
required to support such a scenario and the feasibility
of a power system to accommodate the additional load,
engineers must construct mathematical models for
evaluating the impact on transmission system components. In addition to fundamental calculations for
system load (base load and peak load capabilities) and
overall transmission system capability calculations,
system stability must also be considered. Occasionally, components such as capacitors or phase-shifting
transformers are incorporated to improve stability
on long transmission lines. Modeling the stability of
a power transmission system requires many complex calculations. A first order stability assessment
can be obtained by calculating voltage drop on a line,
evaluating heating of conductors, and mathematically
determining the impact of adding components such as
capacitors and transformers to the design.
In the case of the PHEV study, the total electric energy
requirement for the entire electric vehicle fleet was
relatively modest; however, the cost impact varied
widely by region. High cost sensitivity was predicted
in areas where supply is already tight, such as California and the Northeast. In Midwestern regions, which
traditionally export power, much smaller cost impacts
were indicated. In all regions, cost impacts were twice
as much for day charging versus night charging.
CO2 intensity as a result of PHEV adoption is also
expected to vary by region. In predominantly coal
states, the new PHEV load is likely to reduce the CO2
emission intensity for all charging strategies investigated. In areas that rely more on hydro and renewable energy sources, the CO2 emission intensity may
actually increase if the marginal generation to accommodate the PHEV fleet comes primarily from coal or
natural gas.
Based on engineering calculations for electrical
power system load and associated transmission and
distribution models, the study concluded that the
additional energy demand for charging a fleet of 37
million PHEV vehicles in the year 2030 will not have a
significant impact on the power grid. Additionally, it
concluded that charging electric vehicles is cleaner
at night in the Northeast, the West, and Florida, while
day charging is cleaner in the Midwest.
Automotive Infotainment: A Case Study in
Embedded Systems
Whether a car runs on electricity, gasoline or a combination of both, it’s sure to rely heavily on embedded
or smartphone-enabled electronic systems. According to industry estimates, 80 percent of automotive
innovation in the premium segment comes from the
electronics.
Many of the advances seen throughout the automotive industry—in the areas of safety, emission control,
comfort and quality—would not have been possible
without the use of advanced computer-based control
systems.
Electrical engineers constantly feel pressure to do
more with smaller and faster electronic systems.
Integrating these systems into design processes that
are still managed by people with mechanical engineering backgrounds only adds to the challenge, as do
varying customer demands and regulatory requirements. Modernizing and standardizing electronic
system architectures is a prerequisite for successful
design, industry experts agree. Hans Georg Frischkorn, who leads automotive operations at electronics
service provider ESG, believes that standardization
will help usher in a new era of networked functions. “It
will be very exciting to see the smart car, the smart
grid and the smart home all networked together,” he
says, while warning that the connected car will mean
increasing complexity in electronic systems.
Clarion, the US-based division of Japanese electronics group Hitachi, is testing the networked-services
arena with a cloud-based infotainment service,
“Smart Access”, to add to its offering of traditional incar products. “Smart Access” features smartphone
connectivity and the ability to access a wide range
of apps, including those for car maintenance, safety
management and emergency calling. Telematics
executives say that cars will be connected to the Internet through both embedded and smartphone-based
