Simulate district heating supply
A simple system with a district heating supplier without tariff shows how the components are interconnected and the energy balances work.
Simple energy system with tariffs
The energy system with fuel and electricity tariffs shows how energy costs are calculated from energy demands.
Comparison of different fuels
Different energy supply variants are investigated by the simulation modules eVariant and eValuate.
Simulate time-dependent energy systems
Time-dependent heat and electricity demands and country-specific electricity and gas tariffs cause time-dependent results.
Simulate systems with storage
The project from tutorial 04 is continued to test the cost effectiveness of a thermal storage system.
CHP contracting with stakeholders
With the help of stakeholders, different contracting options―a heat-only contracting, an electricity-heat contracting, and a CHP leasing option―are explored.
Simple cooling supply with CRS
The simple cooling supply is based on a simple recooler with a power-dependent current consumption.
Combined heat, power and cooling
In this tutorial, the project from tutorial 12 is further developed into variants with boilers, CHP, and cogeneration.
Use of waste heat from CRS
Electricity, cooling, and heating demands are covered in a coupled manner using a heat pump and a cold storage tank.
Operating Principle of the Cooling Towers
The behavior of the dry, wet, and hybrid cooling tower components is demonstrated in three cases.
The electricity demands of a commercial enterprise are covered by an electricity supplier and a photovoltaic system.
Storage for peak load management
A photovoltaic system supports the coverage of an electricity demand and feeds surplus electricity into the grid and an electricity storage system.
Off grid system with diesel PV hybrid solution
A local power supply system with diesel generator, photovoltaic system, and power storage is operated independently of the power grid.
Autarkic energy system with power-to-gas
70 single-family homes achieve independence from the power grid through a power-to-gas and a wind turbine, a fuel storage system, a gas turbine, and a fuel cell.
Clausius Rankine cycle
The four state changes during power generation with the Clausius-Rankine cycle are illustrated: adiabatic expansion and compression, isobaric condensation and heat addition.
Two stage steam power generation
Two two-stage steam power processes are compared. In one variant, the feedwater of the steam generator is preheated by heat recovery from the exhaust gas.
Combined heat and power cycle
An electricity demand is met by a combined gas and steam turbine power process.
Compressed air supply with heat recovery
Extending tutorial 40, the viability of a compressor with heat recovery to meet a heat demand is investigated.
To restrict the operation of a CHP due to various conditions, the operational side conditions are used.
Series connection to increase the temperature level
Low- and high-temperature heat generators are integrated into an energy system in series connection.
Compliance with temperature specifications for parallel connection
An energy system with two or more heat generators connected in parallel with different flow temperatures must not fall below a certain mixing temperature.
Variation inclination angle photovoltaic
The dependence of the payback period, net present value, and electric power supplied by the PV system on the tilt angle of the PV system is investigated.
