Circuit breakers, devices carrying out the protection func-tion against overcurrents, are divided into three families including miniature circuit breakers, molded case circuit breakers and air circuit breakers. Miniature circuit breakers available for use in direct current are series S280UC, S800S UC and S800 PV.
In DC grids, the circuit breaker must not provide any current crossing and must absorb surges, since the arc is not naturally extinguished by the system. Additionally, the DC breaker must mitigate the magnetic energy stored in the system inductance and withstand residual overvoltages after current interruption.
The HVDC circuit breaker consists of different topologies namely mechanical HVDC circuit breaker and SSCB. In recent system infrastructure, the VSC based HVDC is utilized and considered the best option for realizing the future multi-terminal HVDC system to integrate the bulk amount of energy over long distances to the AC grid.
Note that other categorizations of energy storage types have also been used such as electrical energy storage vs thermal energy storage, and chemical vs mechanical energy storage types, including pumped hydro, flywheel and compressed air energy storage.
