Ideally, the voltage rise problem would start to appear with transition of the net injection from 3rd to 4th quadrant, which means the generation from solar PV is exceeding the load level at the PCC. Reduction of voltage rise would therefore involve deploying a mechanism to block or reduce the surplus power from entering into the grid. Integration of storage devices with residential PV systems could play a role in this situation by using the surplus energy of PV generation to charge the battery and discharge it at some later stage when PV resources are unavailable or delivering low power. The amount of reduction of voltage rise at a given time instant will depend on the amount of power diverted to charge the battery and this depends on various factors including battery capacity, charging rate, charging method etc. Modeling of storage devices and its application in voltage rise mitigation will be discussed in the following section.
