Energy storage based topologies: In these topologies the required energy is taken from a DC-link (Fig. 5 (c)) or from an energy storage that is connected to the DC-link (Fig. 5 (d)). The former type, which is also called a self-charging (or capacitor supported) DVR, offers a variable dc-link voltage while the latter type provides a controllable DC-link, …

Furthermore, considering the potential risk of the system suffering from a severe voltage sag, an additional energy storage device (ESD) is also required to perform energy conversion with the system. The power and response speed of the ESD should be large and fast enough to meet the actual power demand [22] .

Voltage ''spikes'', ''impulses'' or ''surges'': These are terms used to describe abrupt, very brief increases in voltage value. Voltage transients: They are temporary, undesirable voltages that appear on the power supply line. Transients are high over-voltage disturbances (up to 20KV) that last for a very short time.
