Under the "dual carbon" goals, the large-scale grid integration of renewable energy introduces volatility and intermittency, challenging the stable operation of power systems. With significant differences in time scales and complex energy coupling across multi-energy systems, traditional offline simulations struggle to replicate real system characteristics and hardware-in-the-loop testing.

By leveraging wind, PV, storage, and other equipment models from the iEnergyModel simulation library and incorporating thermal modules, we build an integrated source-grid-load-storage real-time simulation and HIL testing platform for renewable-coupled thermal energy systems, supporting park-level and mega-base scenario simulations.

Typical system architecture and key equipment are shown in the figure below.

• Dedicated Models for Wind-PV-Storage Renewable Energy Systems: Support maximum power point tracking (MPPT) and controllable power modes, meeting simulation requirements for grid-connected and off-grid systems.

• Renewable-Cooling-Heating Coupled Simulation: Integrates wind-PV-storage models with cooling/heating equipment for multi-energy flow coupling, enabling multi-rate co-simulation of integrated energy systems.

• HIL Testing: Connects physical controllers via I/O interfaces or Ethernet protocols to build test environments for renewable energy devices and controllers.

• Full Lifecycle Support: Covers the entire chain from equipment design to operation and maintenance, ensuring autonomous controllability

  
  

It’s applicable to renewable energy source-grid-load-storage demonstration projects. Leveraging the iEnergyModel simulation model library, customers can perform comprehensive operating condition validation in the laboratory, enhancing system operational efficiency and reliability, and accelerating the transformation of renewable energy systems.
