Overview

oHySEM provides a robust framework for optimizing hybrid energy systems, incorporating renewable electricity and hydrogen networks. The library is designed for users needing advanced tools for integrated resource planning, asset integration, system scheduling, and market participation in electricity and hydrogen markets.

Key Applications:

• Optimal Planning & Scheduling: Ensure efficient energy resource management in hybrid systems.
• Integrated Resource Planning (IRP): Plan long-term energy strategies integrating multiple energy sources.
• Market Participation: Engage in real-time electricity markets and future hydrogen markets.
• Asset Integration: Seamlessly incorporate new assets (e.g., renewable generators, storage units) into the system.
• Self-scheduling: Operation planning of the hybrid system.

Features

• Hybrid System Modeling: Simulate and optimize the interaction between renewable electricity and hydrogen systems.
• Market Integration: Enable systems to participate in energy markets and optimize based on market conditions.
• Asset Integration: Support dynamic integration of new energy assets into the system.
• Grid and Stand-alone Systems: Model systems that are either grid-connected or self-sufficient.
• Scalable: Suitable for small- to large-scale hybrid power plants and virtual power plants (VPPs).
