00:00:01,520 --> 00:00:09,110
Hi and welcome back to Olmer tutorial in this session, we want to add a story system as we talked about
2
00:00:09,110 --> 00:00:16,430
it in previous session, we need to add a story system in order to store electricity produced from wind
3
00:00:16,430 --> 00:00:24,710
turbine in the model PV panel in the model to save it for the times that we don't have access to resources,
4
00:00:24,800 --> 00:00:29,300
to renewable resources like the speed or solar radiation.
5
00:00:29,720 --> 00:00:32,300
So to do this, we need to.
6
00:00:33,230 --> 00:00:35,660
There is another thing that I want to mention here.
7
00:00:35,660 --> 00:00:40,130
As you can see, the suggestions are you have two suggestions.
8
00:00:40,130 --> 00:00:42,170
Consider adding a battery or flywheel.
9
00:00:42,200 --> 00:00:48,350
This means that you need to add a storage to your system to be feasible, to model, to be feasible.
10
00:00:48,770 --> 00:00:54,800
And it also mentioned that model does not match results, means that your model is not feasible yet.
11
00:00:55,280 --> 00:00:57,080
It cannot meet the.
12
00:00:58,780 --> 00:01:07,480
The loads that you do find for your model previously cannot meet it, so you need to add a story system
13
00:01:07,480 --> 00:01:08,830
in order to solve this problem.
14
00:01:09,340 --> 00:01:16,500
So by clicking on the component section and storage, this will be pierde.
15
00:01:16,510 --> 00:01:22,590
And again, just like previous stages, we need to define our model.
16
00:01:22,600 --> 00:01:30,850
For example, here we are going to add a generic one kilowatt hour lead acid or let's go with the generic
17
00:01:30,850 --> 00:01:33,800
one kilowatt hour lithium ion battery.
18
00:01:34,540 --> 00:01:42,490
So this is a very generic type of batteries that usually used for modeling energy, renewable energy
19
00:01:42,490 --> 00:01:43,010
systems.
20
00:01:43,330 --> 00:01:52,470
So by and stretch this autumn, this will be a so the DB, there's nothing new here.
21
00:01:52,480 --> 00:02:00,820
So as just like what we did for auto components, we have capital cost, replacement cost and operation
22
00:02:00,820 --> 00:02:01,660
maintenance costs.
23
00:02:01,700 --> 00:02:03,400
What I know it's too much.
24
00:02:03,400 --> 00:02:10,750
So we need to, for example, change this to something like two hundred for capital costs, two hundred
25
00:02:10,750 --> 00:02:18,490
for replacement cost and let's keep it 10 hundred ten dollars for per year for operation and maintenance
26
00:02:18,490 --> 00:02:18,800
cost.
27
00:02:19,720 --> 00:02:21,730
So these numbers are not real.
28
00:02:21,740 --> 00:02:24,140
So did not reference to these numbers.
29
00:02:24,160 --> 00:02:31,030
This is just for continuing to continue making or creating our model.
30
00:02:31,450 --> 00:02:39,370
So our initial model and this is just for the purpose of the not to reference these numbers and.
31
00:02:41,030 --> 00:02:49,100
There is a lifetime of your battery that is very important and it is a very important role in your model.
32
00:02:50,000 --> 00:02:51,970
You can change.
33
00:02:52,610 --> 00:02:59,450
You can use this model, as we mentioned before, in order to do the analyses of the lifetime of your
34
00:02:59,480 --> 00:02:59,980
battery.
35
00:03:00,740 --> 00:03:06,290
And also this shows the width of your battery.
36
00:03:06,320 --> 00:03:13,130
That means we have three thousand cycles of this battery can work during its lifetime.
37
00:03:13,520 --> 00:03:18,240
So and you also can have such a space again and optimized.
38
00:03:18,260 --> 00:03:21,620
But let's keep the optimizer interesting, more optimizer.
39
00:03:22,250 --> 00:03:28,430
And these are showing the initial state of charge and the minimum speed of charge.
40
00:03:29,090 --> 00:03:31,130
So what is the state of charge?
41
00:03:31,130 --> 00:03:35,390
Actually, the state of Georgia is showing how your battery is.
42
00:03:36,370 --> 00:03:42,070
For example, one hundred percent full, it means that the state of charge of your battery is one hundred
43
00:03:42,070 --> 00:03:51,920
percent if it's half half of it use and then you're using a use, the second battery means that's the
44
00:03:52,660 --> 00:03:54,950
state of charge if it is 50 percent.
45
00:03:55,250 --> 00:04:01,300
So as we consider these batteries are not used before and this is the first time that we want to size
46
00:04:01,300 --> 00:04:01,560
them.
47
00:04:01,960 --> 00:04:08,980
So we consider the initial state, if it's one hundred percent or we can change it by sensitivity analyses.
48
00:04:08,980 --> 00:04:19,120
Bottom up minimum, the state of charging means that the state of charge of the battery cannot go down
49
00:04:19,330 --> 00:04:21,220
more than 20 percent.
50
00:04:21,230 --> 00:04:26,410
It means that if your batteries, for example, 10 kilowatt hour.
51
00:04:28,760 --> 00:04:38,150
You can you cannot go, for example, you can use eight kilowatt hour profits and you cannot go down
52
00:04:39,380 --> 00:04:45,420
to two kilowatt hours, so this means that this actually defines the depths of charge of your battery.
53
00:04:45,440 --> 00:04:50,600
So if you don't know about these numbers, just keep the default here.
54
00:04:51,740 --> 00:04:52,420
This is good.
55
00:04:52,550 --> 00:04:57,800
One hundred percent for initial and 20 percent for minimum state of charge and.
56
00:04:59,720 --> 00:05:04,010
Yeah, that's that's that's a view and you can change the name as well here.
57
00:05:04,340 --> 00:05:10,580
So as you cantinas Kermadec section, now we have batteries in a DC two.
58
00:05:10,590 --> 00:05:12,710
So in case of.
59
00:05:15,040 --> 00:05:21,760
In case of excess electricity of the PV during the day, so it goes through the DC line to be saved
60
00:05:21,760 --> 00:05:28,330
in a battery in the DC line, and then when we need the battery, when we don't have, for example,
61
00:05:28,330 --> 00:05:34,660
radiation, we need to use batteries, the energy saving battery, it just come to the DC converter
62
00:05:34,660 --> 00:05:37,120
inverter and then AC and then we use it.
63
00:05:37,600 --> 00:05:42,190
And if we have access to electricity from the wind turbine, it goes to the AC.
64
00:05:42,700 --> 00:05:50,650
And as I mentioned it to me and as we discussed it in a converter section, this time is a rectifier.
65
00:05:50,650 --> 00:05:58,990
So it's first use the rectifier to just change the AC to the DC and then save it to the batteries.
66
00:05:59,560 --> 00:06:06,130
And when we need it again, use the inverter to change it from D.C. to AC and then use it in the load.
67
00:06:06,670 --> 00:06:09,940
So that's a very straightforward process.
68
00:06:10,300 --> 00:06:14,070
So now our system is our model is completed.
69
00:06:14,080 --> 00:06:16,810
Actually, we have two generators.
70
00:06:16,810 --> 00:06:22,960
We have one story system, we have inverter and rectifier and we have our loads here.
71
00:06:24,640 --> 00:06:30,340
And as you can see here in the suggestion power, we don't have any more that suggestion that adding
72
00:06:30,340 --> 00:06:33,760
the storage to our model.
73
00:06:34,150 --> 00:06:36,110
So that's it.
74
00:06:36,130 --> 00:06:42,880
Now we can go and run our model, but we need to finish this session.
75
00:06:42,880 --> 00:06:49,540
And in the next session, we're on our model and we discuss the results and how we need to evaluate
76
00:06:50,200 --> 00:06:51,040
our results.
77
00:06:51,490 --> 00:06:54,970
Until then, take care and enjoy using Comber.
