Volt/var Control Equipment and Methodologies for Robust and Resilient Power System Operations

Traditional approaches and equipment for Volt/var control in transmission systems may face essential limitations in the future considering how power systems are evolving and the expected landscape. Issues and challenges that will arise due to the more stringent operating conditions and performance requirements will drive the need for various different aspects, for example: Would more dynamic compensation will be needed in the system given the impact of renewables, IBRs, new types of loads?, What type of dynamic compensation is needed, power electronic-based, synchronous condensers, BESS?, What is the state of the art and the role of new compensation technologies such as hybrid STATCOMs?, Are new models and tools needed for optimal design and analysis of var compensation solutions?, Are there more efficient and effective ways to coordinate controls across the T&D interface? This panel explores these issues and discusses emerging approaches and technologies for improved voltage control and reactive power management in transmission networks.
