District heating and district management
District heating Hassfurt
Load- and forecast-based generator control with SiMonAs a follow-up to Dollnstein, Hassfurt combines a CHP unit and solar thermal energy to supply a new development – centrally controlled, demand-driven and considering expected solar yield.
The starting point
Supply a new development reliably with renewable heat
A district heating system was required for a new development in Hassfurt, combining heat from a CHP unit and a solar thermal system. Both generators have different availability and operating conditions.
The central task therefore went beyond switching individual units. Heat demand, forecast load and expected solar yield had to be combined in a coordinated generation strategy.
The system scope
Generation, heat network and connected consumers in one system
CHP unit
Solar thermal
SiMon
District heating network
New development
SiMon connects heat generators with distribution and network consumption data. Equipment management, consumption recording and technical fault management are available in one shared operating platform.
The implementation
Transfer experience from Dollnstein to a new generation mix
Represent the plant network
CHP, solar thermal, the heat network and consumers were modeled as one connected thermal system in SiMon.
Forecast loads and yields
The operating logic considers both expected heat demand and available solar yield.
Control generators appropriately
SiMon coordinates generator operation based on load and forecasts instead of responding only to current limits.
Manage operations centrally
Equipment, consumption values and fault states are recorded continuously and visualized for the operator.
The SiMon solution
Use solar yield before conventional generation takes over
Forecasting
Control predictively instead of only reacting
Forecast heat demand and expected solar yield feed into generator control and improve the timing of plant operation.
Load management
Align generation with network demand
Available heat output is coordinated with the actual and expected demand of the new development.
Operations
Make states and faults transparent
Central monitoring shows relevant plant values and fault states without requiring separate subsystems to be monitored individually.
Results and customer value
Coordinated generator operation for the complete heat network
Integrate solar thermal more effectively
Expected solar yield is considered when selecting generators and can be incorporated specifically into the heat supply.
Provide heat according to demand
Load and forecast data support generator operation aligned with the supply needs of the new development.
See operations centrally
Consumption recording, equipment management and fault messages create a shared information basis for the operator.
Hassfurt demonstrates how xNet transfers proven SiMon functions to new plant concepts and adapts them to project-specific generators, networks and operator requirements.
