PV Grid Integration

This software delivers robust functionality to meet diverse requirements in power system integration. It not only handles standard photovoltaic (PV) grid-tie operations but provides additional capabilities for monitoring and optimization. The system employs real-time MPPT (Maximum Power Point Tracking) algorithms with perturbation and observation methods, typically implemented through embedded C code with sampling rates exceeding 10kHz. For grid synchronization, it utilizes phase-locked loop (PLL) controllers with Clarke/Park transformations in the dq-reference frame, ensuring seamless integration with utility grids. The architecture supports both voltage-oriented control (VOC) and direct power control (DPC) strategies, configurable through parameterized function blocks. Communication modules implement IEC 61850 protocols for substation automation and Modbus TCP for data acquisition. The system's intelligent features include adaptive PID tuning using Ziegler-Nichols methods and pattern recognition for fault detection through wavelet transform analysis. These capabilities streamline workflow automation while maintaining compliance with IEEE 1547 standards for distributed resource interconnection.
