DISASTER MITIGATION USING SMART GRID APPLICATION
Abstract
Fire has been a common phenomenon in Australia for thousands of years. It has been a
major factor in the shaping of much of the continent’s landscape. Many fires are believed to have
been started by lightning. For many years, many residents of this continent have suffered fire
losses severally. Some of these losses include burning of vast grasslands that have been used for
hunting purposes while others use. Fire is also useful as the residents use it for clearing their
tracks which were initially dense vegetation.
There are only a few comprehensive records that show the events of bush fire outbreak in
the region. Due to this reason, there is so little that is known pertaining to the cause and the
effects that followed these fires. Lack of this critical information has led to different allegations
about the causes of these fires from different groups of people.
Among the many bushfires that have ever happened in this continent include that of
January 21st
1997. The fire is believed to have Brocken in the Dandedong Ranges and caused
three major fatalities. One was that the fire brought down 42 houses while burning 400 hectares
of land. Other areas that were affected by this particular fire included Eldon, Arthurs Seat,
Gippsland, State Park and Creswick.
In January 9, 1998, there was another fatal bushfire which was reported on New Years
Eve. The fire continued to burn for more than ten days and is believed to have burnt a total of
32,000 hectares of land. Among the part that was consumed by this fire were 22, 000 hectares of
land which was in Alpine National Park. Another 10, 000 hectares that was burnt down was part
of Carey River State Forest. It is suspected that the fire was caused by campfire.
In December, 2002, there occurred another bush fire that was later named the Big Desert
Fire. The fire occurred in two phases-one phase was in the Big Desert Wilderness Park that

3
occurred on December 17. The fire was fanned by the availability of dry fuel and the poor
weather condition in the region. The two fires later joined and consumed 181, 400 hectares of
private property. The fire was however put off by rain that fell on the area on 31 December.
In the year 2003, eight fires were started in eastern Victoria. All these fires were unable to be
contained as they were very furious and spread at a very high rate. The fires joined together to
form a huge fire burning for more than 59 days without being in a position to be contained. The
fires are reported to have burnt over 1.3 million acres including 41 homes and more than 9, 000
livestock belonging to the residents living in the neighborhood. Many thousands of fencing was
also destroyed as a result. The areas that were highly affected included Bright, Mt Buffalo,
Benambra, Dinner Plain and Omeo.
Between 2005 and 2006, there were more than 500 bushfire break outs across Victoria.
This is the period between the New Year’s Eve and the beginning of February 2006. In these
fires, there were four major fatalities. More than fifty seven homesteads were destroyed and
other 359 farm buildings also lost. A total of 64, 000 stocks were also lost. According to reports,
the fire destroyed more than 160, 000 hectares of land. It is approximated that more 60% of this
land was public land while the rest was privately owned.
Between 2006 and 2007, fire agents from Australia responded to more than 1,000 across Victoria
and the surrounding areas. The total piece of land that was destroyed by these fires both privately
and publicly owned was 1, 200, 000 hectares. The two fires that are believed to have been the
toughest were the Great Divide North fire and the Great Divide South fire. Though the fires were
very furious, they were contained by the end of February the same year. The two fires are
recorded to have burnt a total of 1,048,238 hectares of land which was entirely public land.
Above all, the worst bushfire that has ever happened in Australia happened on February 7, 2009.

4
More than 173 people lost their lives. The fires also directly affected more than 78 communities
and many towns left unrecognizable. More than 2,000 properties were also consumed by the fires
including 61 businesses. Other public amenities that were destroyed by the fires include schools,
police stations, kindergartens, community halls, churches, fire and emergency services facilities
and sporting clubs.
Our study will major on this particular bushfire that happened in Kinglake area. This fire
is believed to be the biggest that has ever happened.
Effects of Bushfires in Kinglake
King Lake West is a small geographical region which is located at the upper parts of
Great Dividing Range. It is estimated to be about 65 km north of Melbourne. It acts as the
gateway to the well known King Lake National Park. There are many residents living around this
area on both sides of the Pine Ridge Road. This means that in case of a bush fire outbreak, the
communities usually suffer the consequences. This was the case that has been happening for a
reasonable period of time. Around the area there is also a huge Macedonian church and a
sporting oval for the community that has been standing for years.
According to reports that were provided by residents living around this area, the
composition of all the households which are situated around this area are somewhat varied. Some
of them are retirees who either have been working in or around King Lake. According to a report
given by one of the residents, most of the people living in the neighborhood are not well off and
live in abject poverty and especially those living around Pine Ridge Road. Most of them
confessed to be living in this particular neighborhood just because of how they enjoy the natural
environment that is here and the reason that they are very close to a national park. Other
residents however gave different views for living in this particular area.

Terrain
The terrain here is gentle but drops steeply on the Southern part that leads to the
escarpment. This gives it a very good visual impression. A good number of residents took the
advantage of this terrain to build and settle along this escarpment.
Vegetation
King Lake can be said to be highly covered by temperate Eucalypt trees in almost all
sections except the northern parts of King Lake National Park. The park has however undergone
a great period of drought that has made the forests very dry for the last few years. Houses of
residents living around were mostly surrounded by shrubs and tall ornament trees, shrubs or
garden tress. This made it very delicate for fire extinguishers to put off fire in case of a fire
outbreak.
Dwellings
Many houses around this area are constructed from bricks and iron roofs. Some are
however roofed by tiles though not very popular. Not all houses are also made from these
materials as some are built from fibro-cement sheeting with some bricks to decorate the
structures. Others are also timber structures while other are made of mud bricks which are
mounted on wooden beams and posts.
Statistical Data
In this strategy 173 were confirmed to have died, 500 were injured while more than 72
were hospitalized. 2,029 houses are also believed to have been destroyed where 78 towns were
affected by the strategy, 450,000 hectares of land was burnt down and 7,500 people were left
homeless. Among the public entities that were destroyed include 5 schools, a kindergarten and
three sporting clubs. A total of 9, 450 insurance claims were filed which gave a total of $1.2B.

Main Substations and Effects of Power Blackouts
There are several substationsthat have been mounted around Kinglake area. These
stations are meant to provide an alternative in case there is a power blackout or a shortage in
power shortage. Some of these substations are used to step down electricity while others are
meant to step it up. Among the many places where these substations include Hurstbridge where
even the railway network has been electrified around Eltham area. The idea of electrifying was
catalysed with the fact that there was inadequancy of power supply in the area. Another
substation is situated in Melbourne which is believed to have a national significance as it was the
first large electricity supply network which was then preceded by other few substations in the
country. There is also a substation that is erected at Diamon Creek. Though the substation took

7
long to be constructed, it was finally working as it received most of its power supply from
Greensborough. Another substation is situated in Wattle Glen which was meant to back the
substation at Eltham. Finally there exists a substation at Kinglake zone. This substation supplies
energy to hotels, shops and CFA station that is in the neighborhood. Together with the many
substations that have been constructed to help contain the challenge of power blackout, Energy
Safe Victoria has also been in the front line in the implementation of many electricity measures.
Some of them include helping in sourcing electrical workers and electricians for most of the
bushfire affected areas.
Consequences
Blackouts may be very influential especially to commercial and administrative centres.
Most critical amenities such as hospitals, water and sewerage systems and fire responder systems
should be connected to power back up as they may cause unconted loss in case of a slight
blackout. However, these stations only have fuel that can only last for a few hours from the time
of power black out.
Immediately there is a blackout in a particular area, it is not possible to purchase any
goods without using cash as all electronic payments are made impossible. A blackout that lasts
for 3 to 6 hours means that most fuel stations and refinery industries are forced to stop their
businesses. This leaves the public without any fuel to use for their cars or even power back up
generators. Melting furnaces will already be counting huge losses in case there is a 4 to 5 years
of power blackout as the production can not be reversed.
Goverments in areas affected by continuously power blackout should come up with
emergency fuel storages. This will help in keeping alive those facilities that are very critical to
the society. This fuel should be enough to go for several weeks or even a month.

8
A month without electricity means that transport, water supply, emergency services,
chemical production and critical manufacturing faces widespread outages within the area that has
been affected. Loss of water supply due to a power blackout may lead to many cascading
impacts that may seem fatal to peoples’ lives. Schools, hospitals, nursing homes, offices and
restaurants all depend on water for their operations. Water is also used for sanitation, drinking,
cooling and heating systems among other things used in these facilities. Most manufacturing
industries use water as one of the ingredient in their production process or to transport the wate
to sewerage treatment points. Fire fighters also use water in carrying out out fire emergency
response. It is thus important for them to access sufficient water for them to be in a position to
fight the spread of fire. Without power supply, it would be impossible for heating systems to
operate. During cold seasons like winter, homes may freeze to temperatures that are below
freezing level which might be so hard for human survival. Thus people living in areas which are
affected by such phenomenon use electricity to heat and warm their homes using open fires. In
case there is a fire outbreak due to these open fires, it might be impossible for fire emergency
response to put the fire off in case there is no water after a blackout.
Drones as an infrastructure for fighting Bushfires
Wildfires have been in the increase in the last few years. Fighting these fires have
remained to be an old school game which in many times depend on maps drawn on papers.
Using modern technologies in areas that are mostly affected by these fires has been a real
challenge. The use of new unmanned drones could be the new solution to this challenge. This
might help in managing bushfires and thus change the nature this fight has been for many years.
The use of this technology helps the firefighters and the communities living around these areas

as they can provide more information for fewer costs. This technology is also safe as it does not
put any human being in any harm as not pilots are required.
Fire fighting has been known to be a tricky game for a long period of time. It is always
hard to locate the intensity and the direction a particular fire is taking. The direction of a fire
might change within a few seconds and this becomes a real challenge to fire fighters. The use of
drones can help in gathering more information about the fire at hand than other forms of fire
fighting techniques. They efficiently send information they gather to quickly to fire fighters at
the ground. The fire fighters thus can be able to react in accordance to the information given and
know where to start.
In most areas, fire fighters are usually sent to fight fire with tablets and smart phones.
Through these gadgets they can acquire and send information to one another while managing a
fire outbreak. In areas where internet connection is weak, the use of these gadgets can be
interrupted leading to poor communication. Bushfires are known to occur in rural areas where
the terrain is poor and the sending of signals differs from one particular area to the other. Drones
are designed in a way that they can provide internal signals even in dead zones making them
ideal for use in almost all terrains.
.Where internet connections are good, a lot of information pertaining fire outbreaks may
be given to fire fighters. Most manned airplanes were initially not installed with communication
gadgets and took pictures about the affected areas. This particular information seemed to be so
outdated because most of these manned helicopters took pictures and other infrared images in
trying to map fire perimeters. This is obviously risky and costly. This makes the fire fighters to
fly over the bushfire either once or twice each day.

10
Drones, on the other hand are cheaper in comparison to manned planes and helicopters.
More than one drone can even be launched at once. One drone is estimated to cost as little as
$2,000 to fight fire for eight hours. A manned helicopter goes for only an hour for the same cost.
Drones can stay working for a day or even days which is not possible for manned planes.
Drones are designed to use infrared technology that allows them to see through the
smoke. They also have the capability of flying in some extreme conditions which are dangerous
for tankers and manned helicopters. They also have special sensors that enable them sense a
slight temperature difference in objects.
They have features that give real-time data where the images captured are downloaded by
fire fighters at the ground. The information is then interpreted and necessary measures taken.
The technology can thus be taken to be the next fire fighting tool. It is much cheaper and
more reliable. The technology also can apply both in rural and urban fires as it can work even in very
extreme conditions.
