This repository serves as the comprehensive data resource and methodology documentation for Marine Hydrokinetic (MHK) device integration into power systems. It provides complete simulation models, FMU (Functional Mock-up Unit) implementations, synthetic test grids, and integration methodologies developed through extensive research on grid-connected marine energy systems.
This resource enables power system researchers and engineers to study the integration of Wave Energy Converters (WEC) and Current Energy Converters (CEC) into electrical grids. The repository includes:
- Complete device models (WEC and CEC) in Simulink format
- FMU exports for co-simulation with various power system analysis tools
- Synthetic grid model compatible with PowerFactory and PSSE
- Integration methodology and example implementations
- Ready-to-use test case with pre-integrated components
Complete device models for Marine Hydrokinetic systems:

MarinePowerDynamics.jl is a Julia-based simulation tool for studying the dynamic (time-domain) behavior of marine energy resources and their interaction with electric power systems. It extends PowerDynamics.jl with specialized marine PTO (Power Take-Off) modeling capabilities, enabling co-simulation between grid dynamics and WEC mechanical systems using external time-series data from WEC-SIM. The package supports realistic grid event simulations and provides a LinearPTO node model for dynamic coupling of wave energy converters to power grids.
