Analysis of Grid Code Requirements for Wind Power Dynamic Model

Abstract

Renewable energy and energy storage system are a hot topic today since the global warming is related to the burning of fossil fuels. Renewable generations using wind, solar and wave sources are integrated into power system for securing economic feasibility. However, grid-connected wind power having its natural variability greatly may affect stability of power system, and TSO (Transmission System Operator) and ISO (Independent System Operator) have developed grid code for wind power. Especially, technical requirements for testing and simulation are specified in grid code because GCC (Grid Code Compatibility) is ascertained through onsite testing and computer simulation. Therefore, the simulation model requirements should be understood clearly from the early stage of project, and the exact models and reports can be delivered to TSO and certification body on time. Namely, wind turbine manufacturer should deliver its dynamic models, model validation report and test report, on the other hand, wind power plant owner should deliver its dynamic models and commissioning report. The accurate understanding of different simulation model requirements presented from various national grid code avoids simulation modeling error.
