A Preliminary Exploration of Standardized Modular Modeling Methodology for Renewable Generation Suitable for Power System Security and Stability Analysis

(SSS) analysis. This motivates the urgent demand for accurate and efficient models of renewable generation. In recent years, the modeling of renewable generation typically conforms to the "model-follows-the-device" approach. However, the types and structures of renewable generation are diverse, and their control characteristics differ significantly. Highfidelity modeling of each type of renewable generation unit is prohibitively difficult due to the challenges of data acquisition coupled with the highly repetitive and labor-intensivenature of the process. Both typical digital models and widely used manufacturer-provided black-box models are difficult to employ for the simulation and analysis of system operation and control under diverse operating conditions. The "model-follows-the-device" modeling approach can no longer satisfy the development requirements of the new power system. This paper proposes a technical roadmap and methodology based on a "model-leads-the-device" paradigm for constructing a standardized model library for massive heterogeneous renewables. This foundation supports the future standardization of power electronic device design and grid compliance testing, paving the way for aligning device development with system-level requirements. The approach involves the technology of: (1) feature extraction and classification of control characteristics for various generation units; (2) structural design of functional modules; (3) control mode and parameter identificatio; (4) model testing and evaluation; and (5) standardized design of control modules and parameters tailored to different grid integration scenarios, such as renewable energy delivery from desert and gobi regions, large-scale renewable integration via HVDC transmission, and large-scale offshore wind power transmission. This paper takes photovoltaic (PV) power generation units as an example, and elaborates on the modeling methodologies and effectiveness of the standardized modeling for renewable generation. The results demonstrate that the technical roadmap for standardized modeling is able to balance the accuracy, efficiency, flexibility, and usability for simulation and analysis.
