Why is control design important for inverter-based resources in weak grid conditions?
Control Design: Operation of inverter-based resources in weak grid conditions can be an important consideration in the control design for manufacturers. In the design process, manufacturers evaluate the capability to comply with performance requirements with different system strengths for predefined product configurations.
How will inverter-based resources affect the electric power grid?
Increasing Penetration of Inverter-Based Resources and “Weak Grid” Conditions: Inverter-based resources (e.g., wind and solar) continue to be a significant component of new generating resource additions. As the resource mix and technologies interconnecting to the BPS continue to evolve, the electric power grid will undergo changes.
How can inverter-based resources be mitigated in a weak grid?
The most important aspect of identifying and mitigating issues with inverter-based resources in a weak grid is coordination and communication between the TP, GO, and equipment manufacturer. Increased coordination between these entities helps ensure any weak grid issues that may arise can be addressed and mitigated effectively.
