Content Workshop aproach!!Development
aproach..!!

• 1. (23 August) Introduction to studies made by
  the use of EnergyPLAN. Discussion of participants
  ideas of PhD projects and potential use of the
  model.
• 2. (30 August) Details inside the model. How
  does it work? How are the modelling of specific
  components, units etc? Discussion of
  PhD-projects Strengths and weakness of the
  model?
• The period between 23 August and 5 September
  Participants install the model and make familiar
  with the model and make som preliminary analyses.
• 3. (6 September) Discussion of participants
  analyses. Results, problems, room for
  improvements of the model!!! Etc..

15
Regulation strategies

• 1. Meeting heat demands
• 2. Meeting both heat and electricity demands
• 3. Like 2 BUT reduce CHP also when is needed for
  stabilisation reasons
• 4. Like 1 BUT meeting triple tariff.

16
Limitations

• Stabilisation share
• Minimum CHP 3 level
• Heat pump share of district heating production

17
Eventual market optimisation

• Marginal production costs compared to market
  prices define the production

Electrolyser

• Produce fuel in the case of critical excess
  production
• Heat replace 1. boilers, 2. CHP and 3. heat pumps
  in the relevant DH-group.
• Fuel is used to replace fuel consumption in CHP
  and boilers in the relevant DH-group.

20
Electricity storage

• Fill storage when positive critical excess
  production
• Empty storage to replace condensing power plant
  production
• Iteration of storage content untill the content
  in the beginning of the year is the same as in
  the end.

21
Heat storage

• In two situations the storage can be loaded
• A Increasing the use of HP in situations with
  electricity export.
• B Moving the electricity production from
  condensing plants, epp to CHP plants
• In two situations the storage can be unloaded
• C Reducing the CHP production in situations with
  electricity export
• D Reducing the boiler production.
• B is secondary to A and D is secondary to C. The
  four loading and unloading cases are used in the
  following order C-A-B-D.
