Aalborg University, September October 2005PhD-course: Energy System Analysis I: Introduction to the EnergyPLAN model Henrik Lund Aalborg University Denmark
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..

The EnergyPLAN Model Energy System Analysis Model - Excel~Visual Basic~Delphi Pascal - Main focus: Compare different regulation systems ability to integrate and trade RES (Wind) - Simplified modelling of energy system.
EnergyPLAN Model 6.0 Input Output Distribution Data: Demands Fixed electricity Flexible electricity District Heating Electricity District H. Wind MarketPrices • Results: • (Annual, monthly and hour by hour values) • Heat productions • Electricity production • Electricity import export • Forced electricity surplus production • Fuel consumption • Payments from import/export • CO2 emissions • Share of RES Solar IndustrialCHP PhotoVoltaic RES Wind and PV Capacities (MW) Distribution Factor Solar Thermal and CSHP (TWh/year) • Regulation strategy: • 1. Meeting heat demand • 2. Meeting both heat and electricity demand • Electricity Market Strategy: • Import/export optimisation • Critical surplus production: • reducing wind, • replacing CHP with boiler or heat pump • Electric heating and/or Bypass Capacities & Efficiencies CHP, Power plant, Heat Pump, Boiler Heat Storage Regulation Market prises Multiplication factor Addition factor Depend factor Marginal production Cost (Import, export) Stabilisation demands Fuel Types of fuel CO2 emission factors Fuel prices

Modelling of NordPool - Standard system price hour by hour distribution (based on recent years) - Construction of “Wet” “Dry” and “Normal” years (Hydro in Norway) - Modelling of influence for DK trade and splitting in price areas due to bottle-neck in transmission - Modelling of influence from Trade on the German Boarder.
Conclusions: • If wind production exceeds 5 TWh (equal to 20%) investments in CHP regulation and Heat Pumps are feasible. • Such investments at the same time makes wind power more feasible. For production costs of 220 DKK/MWh and CO2-prices of 100 DKK/t the feasibility of wind power raises from 6 TWh in the reference system to 11 TWh in the “Heat Pump” system.
Sensitivity Analysis • Increase in Heat Pump Costs • Variations in CO2 payment • Change in Wind Power costs • Change in fuel costs • Change in CO2 influence on Nordpool • Change in Nordpool average price • Change in import/export to Germany • Change in Nordpool price variations
