okay thank you for uh this nice videos not even aware of that pretty well
00:00:51
done i'm very pleased to see that the first session of the day
00:00:56
it's about energy no energy is one of the fundamental team for modern society and it's
00:01:01
one of the main challenges for the next uh fifty years for the whole mankind
00:01:06
so what i'm going to talk about is about the user java disadvantage is stored into the margaret's
00:01:11
why this is one of the hot topics all that nobody's research and industrial
00:01:16
technological transfer what especially because the context is the following this up
00:01:21
i charge which is showing the appetite of the uh the models aside in
00:01:27
terms of energy the size of this part chart is proportional to the
00:01:31
primary energy consumption it's that you don't use asian of uh uh at the global level but you
00:01:37
can see i was actually chew elements the first one is the growth of this by choice
00:01:41
the second fundamental element is that the green part of this by chart which
00:01:45
are also to the to the uh energy conversion from renewable sees
00:01:48
growing in this going for the first time in the last decades which
00:01:52
are the consequences of this growth all the consequence is that
00:01:56
you're inserting into energy systems in power systems a
00:02:00
lot of uncertainties so typically the challenge
00:02:04
in our complex or grade used to keep the system in stable operating condition
00:02:09
especially on the left of this crap you see injections of uncertainties
00:02:13
and the more integrated the nobles them or uncertainties you insert in your system
00:02:18
that needs some balancing action which are essentially the control actions that you
00:02:22
are inserting your system now the but i think actions typically um
00:02:27
providing the power systems at being given by hydropower plants gas part
00:02:31
probably power plants or other kinds of standard power plants
00:02:35
the potential used to use these are the storage and that's what we're interested to talk with so
00:02:40
the fact is that the more integrity your balls the more you need balancing systems
00:02:45
and the question is what kind of devices we can imagine for the
00:02:49
future smart ways to keep the system balance of the building
00:02:53
now especially if there are chew the interesting aspect for interesting i've aspect as it to you
00:02:59
uh usage of this with storage the first one is that you wanted to dispatch locally
00:03:03
with the possible local problem at distribution level not to the box system that
00:03:09
second element is to reduce the usage of stand there that a balancing systems typically provided by
00:03:15
a gas fired power plants for instance and the third objective is that you wanted
00:03:19
to satisfy also local object it's how you typically sold this kind of problems
00:03:25
but you have is that you have a sector of uh uh by consumers
00:03:30
for instance buildings which are also producing power for instance viable slides or via wind turbines for
00:03:37
you want to that these aggregate that a thorough jenny those sites of of prose humorous
00:03:43
nice to be fully controllable or fully these possible if i if you let me use this language there
00:03:50
in this case we wanted to use the service storage is the these big battery that you see connected to these local system
00:03:56
so essentially habit shoes fan still problem you wanted to solve the problem at day ahead
00:04:01
level so wanted to compensate for the uncertainties that you know twenty four hours before
00:04:07
and then when it comes in operation you want us all the uncertain let's say all the uh the
00:04:12
problems of the rising up at the level of up seconds minutes or hours into the operation
00:04:18
now is it these technically and economically feasible and try to convince you that yes is possible
00:04:23
uh this is one of experimental infrastructure we have on campus is in the form of a big battery
00:04:28
is up one mega what battery which is is already into the electricity in the in the region what the the trees the buildings
00:04:35
and this is what ah an example hopkins so in that top graph you see uh
00:04:41
so on which is a market brady what if backspaces the
00:04:44
uncertainties associated to the pros some chance of a subset
00:04:49
of building up the path you see that in the middle of the day there is a lot of answer
00:04:53
i mean the button figure you see that we're able to dispatch maybe to control
00:04:58
they start trajectory energy obvious at the buildings is actually zero uncertainties and
00:05:04
the services provided by the these kind of battery the question is
00:05:08
i'm trying i can because i hope that the committee that is technically feasible is it economically feasible
00:05:13
so this graph showing you uneconomical assessment are transferring
00:05:18
the dispatch from sets was a power plants
00:05:21
down to distributed energy storage systems you can see that the green curve which is the cost of these
00:05:28
uh in this with energy source just permit the the standard provisional ancillary services like balancing with that
00:05:34
standard gas fired power plants is crossing the blue and red curves which is this real storage after
00:05:41
ten years twelve years which means that after these amount of peer period of time
00:05:46
using energy sources me the formal that's okay because thirties economically more viable
00:05:52
additionally if you look at what this next slide please oops
00:06:02
okay well the next slide was uh a graph that was coming from a
00:06:06
study published in nature yeah thank you very much um last year
00:06:10
which is showing the trend of the cost of perk about our energy source system we are at
00:06:15
the level of well four hundred five hundred dollars per kilowatt hour and is going down
00:06:20
journalism showing you before is done with the current cost was energy storage systems
00:06:25
in fact there is and these crappy showing that the potential is even more important in the next five to ten years
