Project: Development of tools for effective control of large PV power plants

Acronym Pvtool (Reference Number: 76)
Duration 01/09/2018 - 01/07/2021
Project Topic Large PV power plants need to ensure a smooth injection of the generated renewable power into the grid where they are connected, while providing the required ancillary services. Depending on the grid nature, such requirements can differ considerably, ranging from frequency or voltage support for PV power plants connected to power systems based on conventional synchronous generators, to grid-forming capability in systems or microgrids where PV is the main generation source. The PVtool project aims at developing relevant control architectures and control algorithms to ensure optimal performance in different kinds of systems. Such control schemes will take into account the distributed nature of the different elements (inverters, transformers, energy storage systems, reactive power compensation equipment, cables) and the necessity for control coordination. The option of using or not communication systems in different control layers will be analyzed, suggesting appropriate architectures depending on the given requirements. The risk for interactions between power converters and different system elements will be investigated in order to develop methodologies and tools that ensure the overall system stability. Potential unstable resonances will be carefully analyzed and the key quantities and elements that can trigger them will be identified. The developed methodologies will be applied to selected case studies inspired from actual installations. The project aims at developing and implementing tools to allow PV power plant engineers to design the controllers of large PV power plants in a systematic way.
