eRoots has developed state-of-the-art tools to support integration of renewable energy and hydrogen into the power system. Our team has been involved in a wide variety of grid integration consultancy projects, such as large scale solar PV power plants, offshore and onshore wind power plants. The solutions span the following categories:

Development of automatic tools for the integration of renewable power plants and hydrogen
Electrical installation design and sizing
AC and DC collection system studies by leveraging our AI algorithms
Precise short-circuit calculations accounting for converters' current limitations
Grid code analysis and compliance studies
Small-signal stability analysis to identify interactions and instabilities
Plant and converter controller analysis and development

HVDC and FACTS systems

HVDC and FACTS technologies are indispensable to enable efficient long-distance power transmission, enhancing grid stability, and facilitating the integration of renewables.

In today's rapidly evolving energy landscape, the demand for reliable, efficient, and sustainable power transmission is paramount. High-Voltage Direct Current (HVDC) and Flexible AC Transmission Systems (FACTS) technologies are playing increasingly critical roles in addressing these challenges. We help partners in topics such as:

Design and sizing of HVDC links and FACTS for different applications
Design of power converters for HVDC and FACTS applications
Modular Multilevel Converter (MMC) design and control for HVDC and FACTS applications
HVDC links, multi-terminal and meshed networks control design
Current flow controllers for HVDC grids optimization
Interaction and stability analysis involving HVDC and FACTS converters
EMT and phasor-based simulations of modern power systems containing components based on HVDC and FACTS devices

Expansion planning

We employ our steady-state software and dynamic expertise to plan ahead the expansion and development of power networks in islanded regions and weak systems.
