Design Optimisation of Wind- PV-Microhydro-Multi-Energy Storage System for a Net-zero: Campus Case of University of Aberdeen Old Aberdeen Campus

Aerk Dimri, et. al

School of Engineering University of Aberdeen

Abstract:  Combined Heat and Power (CHP) units supply around two-thirds of the electricity that is consumed in the University of Aberdeen, s Old Aberdeen campus. As the CHP unit nears the end of its designed life., this paper explores the most cost-effective Hybrid Renewable Energy System (HRES) configuration that can replace the CHP and achieve the university , s emission reduction target. This paper first analyses the current CHP and grid energy system and presents the electricity demand and the equivalent carbon emissions of the Old Aberdeen campus. Then the potential for renewable electricity generation is explored which includes an assessment of the wind energy resources, solar irradiance, potential locations for solar panel installation on the University property, and the potential of micro-hydro installations on the river Don. The electricity demand and the renewable energy data are then used to find the most cost-effective HRES configurations for multiple energy scenarios using MOHRES software. The most cost-effective HRES solution in the context of the Old Aberdeen campus achieves net-zero electricity at an investment cost of 7.1 M£ which is paid back in 25 years with an overall energy cost of 0.18 £/kWh. This cost is 14.3% lower than the current cost of electricity supplied by the grid. The annual cost of carbon offsets that need to be paid between 2040 to 2045 to balance emissions from grid electricity using the recommended solution is projected to be around £35.,000.

Abstract: Internet of Things (IoT) is the interconnection of physical objects and devices to the internet and in turn to each other to aid decision making. This paper deals with automation of gardening systems using IoT. With water resources becoming ever so scarce by the day, it has become imperative that we use water extremely judiciously in all walks of our daily life. We track the environmental conditions such as humidity of the soil, and temperature and take an appropriate route towards the problem. Based on the data collected, we run algorithms which help keep the garden in good condition and at the same time using resources optimally.

“Landscape with a clump of trees” 1844 Théodore Rousseau

 

 

“Keep a green tree in your heart

and perhaps a singing bird will come”. 

— Chinese proverb

 

The condition of campus gardens, trees and landscaping is a central element of ambiance, brand identity, environmental instruction and even revenue to education communities when tied to charitable donations.   The Tree Care Industry Association (TCIA) is trade association of 2300 private tree care firms that is also an ANSI-accredited standards developer.  It has several titles relevant to education communities and posts drafts of best practice titles at the link below:

Current Projects & Public Review Periods

Last year we tracked a revision of TCIA A300 that asserted leading practice for lightning protection has been released for public consultation.   The consultation period closed and, like many standards setting organizations, leading practice discovery has been impeded by the circumstances of the pandemic.

We encourage our colleagues in business units responsible for lawns, trees, gardens and pathways to participate in the TCIA standards development process (Learn more HERE).  Stakeholders in any interest category may communicate directly with Amy Tetreault at the Tree Care Industry Association, (603) 314-5380, atetreault@tcia.org, 136 Harvey Rd # 101, Londonderry, NH 03053.

We maintain the TCIA standards catalog on our periodic Bucolia and Pathway colloquia.   See our CALENDAR for the next online meting; open to everyone.

Evensong “And So It Goes”

The Ballad of Barbara Allen

In every heart there is a room
A sanctuary safe and strong
To heal the wounds from lovers past
Until a new one comes along

[Verse 2]

I spoke to you in cautious tones
You answered me with no pretense
And still I feel I said too much
My silence is my self defense

[Chorus]

And every time I’ve held a rose
It seems I only felt the thorns
And so it goes, and so it goes
And so will you soon I suppose

[Verse 3]

But if my silence made you leave
Then that would be my worst mistake
So I will share this room with you
And you can have this heart to break

[Chorus]

And this is why my eyes are closed
It’s just as well for all I’ve seen
And so it goes, and so it goes
And you’re the only one who knows

[Verse 4]

So I would choose to be with you
That’s if the choice were mine to make
But you can make decisions too
And you can have this heart to break

[Outro]

And so it goes, and so it goes
And you’re the only one who knows
