Title: Using Co-Simulation to Study the Integration of Offshore Wind Plants

Abstract: The continuous push for decarbonization and electrification has led to increasingly higher penetrations of inverter interfaced renewable generation. Offshore wind generation has become one of the technologies of interest and now represents a sizable share of many renewable energy portfolios of coastal states and nations. Reliable integration of offshore wind energy requires diligent and detailed studies with high fidelity models, some of which are not generally available to system planners.  This talk will provide an overview of offshore wind technology and integration efforts in the united states and other places around the world, discuss the absence of adequate, open control architecture HVDC models suitable for offshore wind integration studies and demonstrate how co-simulation can be used to overcome some of the modeling limitations. Example studies of integrating a major offshore wind plant to a northeast state will be provided.

BiographyBruno Leonardi is a Senior Technical Leader in Grid Operation and Planning Group of the Power Delivery & Utilization Sector at the Electric Power Research Institute (EPRI) and joined EPRI in 2018. In EPRI, he has worked on various topics related to power system dynamics and controls, including, but not limited to: development of dynamics models for wind/solar plants, subsynchronous oscillation screening studies, HVDC planning and applications to offshore wind integration, voltage control in weak grids, EMP and GMD system impacts. Prior to joining EPRI, he was with GE Energy Consulting, in Schenectady, New York, where he acted in various roles. As a Software Developer, he led the development of various GE PSLF features, most notably, the development of a parallel solution architecture for the PSLF dynamic engine and the core engine for PSLF’s Geomagnetic Disturbance package. As a consultant, he supported a wide range of studies spanning GE’s product portfolio, including stability studies for wind plants, solar plants, BESS, STATCOMs, HVDC transmission, gas and steam plants, series capacitors and synchronous condensers. He has also been involved in multiple subsynchronous resonance screening studies and plant interconnection studies. In modeling, he has led the development of GE’s weak grid wind models, conversion of firmware controls to positive sequence models, including OEM specific weak grid controls, GE’s wind inertia controls and GE LV5 solar inverter controls. He has also supported model validation of positive sequence models against staged field tests during commissioning for dozens of wind/solar plants around the world. His areas of interest include power systems stability and control, equipment dynamics, modeling and application, computational methods, subsynchronous oscillations and impacts of GMD and EMP events on system and equipment. He is a Member of the IEEE PES and CIGRE. Education and training: Electrical Engineering, Ph.D., 2011, Iowa State University, USA; Electrical Engineering, B.S., 2005, University of Sao Paulo, Brazil.
