B4.
Mission
To facilitate and promote the progress of engineering and international exchange of information and knowledge in the field of Direct Current (DC) equipment/systems and electronics applications. To add value to this information and knowledge through synthesis of advanced practices and development of recommendations.
Technological Scope
Direct current equipment and systems including converter technologies and semiconductor devices. Power electronics for AC systems and power quality improvement, advanced power electronics and application.
Scope
Within its technical scope of activity, Study Committee B4 deals with DC systems and Power Electronics (PE) equipment in both transmission and distribution systems. The Study Committee also addresses DC converters for integration of distributed renewables (PV) and energy storage as well as power quality control. SC B4 covers the entire spectrum of DC systems and PE devices including technology, specification, design, application, operation, maintenance, refurbishment of DC systems and FACTS devices.
Within this framework, additional specific areas of attention include:
Theory, technologies, design, performance, operation and maintenance, and application of DC converters and systems; Theory, technologies, design, performance, operation and maintenance and application of FACTS devices; DC interconnectors and establishment of DC grids/multi-terminal HVDC systems to increase power transfer capabilities and reduce existing grid congestion (AC grid layer), to enable electricity trading, share spinning reserve and reduce energy costs; Converter technologies with Grid Forming control capabilities for improving and enhancing reliability and stability of PE controlled power system with increasing integration of renewable generation and battery storage resources; Standardization and digitalization of Offshore DC platforms; Implementation of interoperability of HVDC systems built by different HVDC manufacturers for flexible and reliable operation and control of power system interconnected through HVDC system; Implementation of DC and PE technologies in distribution system for better power quality control; MVDC applications such as large solar park connection; Refurbishment and upgrade of HVDC systems and FACTS devices; Inverter-based energy storage.
