Matching the energy storage DC voltage with that of the PV eliminates the need to convert battery voltage, resulting in greater space efficiency and avoided • DC circuit breakers to help
The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course,
Dealing with the fast-rising current of high voltage direct current (HVdc) systems during fault conditions, is one of the most challenging aspects of HVdc system protection. Fast

ABB’s solid-state circuit breaker can detect and respond to a short circuit fault 100 times faster than a mechanical circuit breaker. Energy storage systems and their corresponding electrical grid services are strongly affected by the downtime in case of an internal fault.
The solid-state circuit breaker will be around 100 times faster than traditional electro-mechanical breakers. Its speed maximizes the performance of power distribution systems, while maintaining service continuity. The new ABB breaker will also improve safety and protection for people and equipment.
The ABB solid-state breaker concept works by replacing the traditional moving parts of an electro-mechanical circuit breaker with power electronics and advanced software algorithms that control the power and can interrupt extreme currents faster than ever before.
A key point to note in the case of these traditional circuit breakers is that they switch the circuit causing arcs, and the breakers deploy various mechanisms to extinguish the arcs during the switching of mechanical contacts, such as using arc chambers, arc deflectors etc.
The paper performed an analytical study based on the circuit breaker operation in the high voltage direct current application to highlight the technological improvement and circuit topologies. A comparative analysis towards different types of circuit breakers to achieve efficient fault current isolation is presented.
Solid-state technology guarantees an extremely fast interruption and clears a fault in a few microseconds. In comparison, a mechanical circuit breaker with the same frame size takes a few milliseconds. ABB’s solid-state circuit breaker can detect and respond to a short circuit fault 100 times faster than a mechanical circuit breaker.
