An energy storable HVDC unidirectional power transmission system is proposed. The system includes adiode full bridge rectifier and a MMC with EDLCs. DC power and voltage are controllable by controlling on-state SM numbers. Stored energy is limited in a certain range by energy management control.
This paper has proposed an HVDC system with energy storage capability and one-way power (output) transmission. The system mainly incudes a diode full bridge rectifier and a single Modular Multilevel Converter (MMC). Supercapacitors (EDLCs) are used as energy storage elements of the system.
For the proposed energy-storable system, the requirements to the energy storage devices (dc capacitors) are: large capacitance for the energy storage capability, high power and energy density to reduce the size and weight of a single submodule; long cycle life for the frequent charging and discharging of short-term energy storage.
