The document summarizes the ORIGIN project, which aims to optimize energy storage and demand-side management in microgrid systems across three European communities. It discusses the project goals of aligning energy demand with local renewable supply through forecasting, monitoring, and orchestrating energy use. Hardware has been installed and a demand response system is going live in November 2014 with the goal of reducing imported energy and carbon emissions by over 20% through more efficient use of on-site renewable generation and storage.

Biomass boilers 350kW 630kW
Current energy use 39kWh/m2
(Note 1)
34kWh/m2 1.5kWh avg. daily

Note 1 – 88.6% compared to UK average
Note 2 – 40.5% compared to Portuguese average

5. What has the EU funded?
 Orchestration of energy use within a community –
to save imported energy / carbon
 How? - Alignment of energy demand with (local)
renewable supply
 Prediction of demand and supply and orchestration
of energy use
 Deployment of smart energy monitoring, control
and communication hardware
 A sustainable economic model

7. Scotland’s Wind Generation – Capacity Factor =
33%
Efficient and effective storage is required if benefits
of renewable generation are to be realised
Without storage - thermal generation will remain
the dominant generation technology
Diversity of renewable generation will help

9. How can ORIGIN help?

10. • Forecast and
observation data
for c37 sites
• Predicts next 24
hours weather at
hourly precision
every hour
• Uses a neural
network approach
Corne et al, Heriot Watt University, MACS

11. Wind-speeds at Findhorn for a 7-day period in April
Performance of the ‘24-hour ahead’ ORIGIN forecast (blue), compared with the
‘24-hour-ahead’ MetOffice forecast (red), with actual windspeed in green.

12. Met Office forecast mean absolute errors (in metres per second)
vs ORIGIN error, forecasting wind speed at Findhorn
Horizontal axis is ‘hours ahead’.

13.  For effective automated demand side
management we also need to:
 Forecast the electrical needs of the community
 Measure and forecast the thermal needs of the
community
 Expensive to automate and retrofit
 Alternatively you engage the residents with an
ergonomic user interface
 35 automated buildings at Findhorn
 40 user engaged buildings

14. Progress: Electrical demand prediction

• Disaggregate consumers
into load profiles
• Use this to predict demand
• Provide contextualised
response schedule: not all
residents are equally likely
to respond

16. Decide what to reschedule

17. Identifying Opportunities

19.  Hardware installed and recording data from
December 2013
 Demand response system goes live in Findhorn
on 5th November 2014
 Tamera and Damanhur later that month

20. What do we plan to achieve?
 More efficient use of installed renewable
generation and storage
 Less imported energy to the communities
 Community confidence in use of energy
 Reported carbon dioxide emission savings
 20%+ savings should be achievable but
potential for more
 Demand side management is essentially
energy storage - usually in hot water or the
fabric of the building
