Intelligent Customization Process for MTP Adapter Modules for Photovoltaic Power Plants

MTP-based intelligent customization enables plug-and-produce integration of photovoltaic modules, allowing rapid engineering, flexible deployment, and seamless automation across PV power plants.

Overview of MTP in Modular Automation

The Module Type Package (MTP) is a standardized digital description of a process module, enabling modular plants to be engineered, integrated, and operated efficiently according to the VDI/VDE/NAMUR 2658 standard . In the context of photovoltaic power plants, MTP adapter modules can represent inverters, trackers, or monitoring units, each described as a Process Equipment Assembly (PEA) with defined services, interfaces, and HMI templates . This allows modules to be plugged into the plant's Process Orchestration Layer (POL) without extensive reprogramming or manual integration .

Intelligent Customization Process

1. Module Definition and Engineering Using tools like MTP DESIGNER or zenon MTP Suite, PV modules are engineered by importing system schematics (P&IDs) and generating automation services automatically . Each module includes:
   • Functional services (e.g., power output control, fault detection)
   • Communication interfaces (OPC UA tags)
   • Local visualization and HMI templates for monitoring and control
2. Standardized Integration The MTP file exported from the engineering tool contains all necessary information for integration into the POL. This ensures controller-independent deployment, allowing modules from different manufacturers to interoperate seamlessly . The plug-and-produce approach reduces time-to-market and enables rapid reconfiguration for plant expansions or technology upgrades.
3. Process Orchestration and Automation Once integrated, the POL orchestrates multiple PV modules, enabling:
   • Automated startup and shutdown sequences
   • Real-time monitoring and diagnostics
   • Dynamic adaptation to changing solar irradiance or grid requirements
   • Efficient energy management and predictive maintenance
4. Reuse and Scalability MTP modules can be reused across different PV plants or redeployed after maintenance, supporting agile production and resource efficiency . This modular approach allows operators to scale capacity or integrate new technologies without redesigning the entire plant.

Benefits for Photovoltaic Power Plants

• Faster Deployment: Pre-engineered MTP modules shorten commissioning time.
• Flexibility: Modules can be reconfigured or upgraded independently.
• Interoperability: Standardized interfaces enable multi-vendor integration.
• Operational Efficiency: Automated orchestration reduces manual intervention and optimizes energy output.
• Cost Reduction: Modularization lowers engineering and maintenance costs while supporting incremental plant expansion.

Conclusion

Applying intelligent MTP customization to photovoltaic power plants transforms traditional PV system deployment into a flexible, scalable, and automated process. By leveraging standardized module descriptions, plug-and-produce integration, and process orchestration, operators can achieve faster commissioning, easier upgrades, and optimized plant performance while maintaining interoperability across diverse equipment and vendors .
