Basically, if the voltage is too high and outside of the dead band, the inverter absorbs reactive power. This has the impact of reducing the voltage. Renewable-based DER also brings challenges to the electric transmission and. . The capability of DER to help control these voltage changes on the power system becomes important. Beyond converting DC to AC power, they are increasingly tasked with supporting the electrical grid. The IEEE standard is not prescriptive as to how smart inverters shall support grid voltage management, instead it requires a set of capabilities that smar inverters could utilize to support voltage management.
