One way to achieve this is to have the inverter supply or absorb reactive power in response to fluctuations in grid voltage. HECO RULE 14H/CPUC RULE 21 is requiring all certified grid-support inverters, or smart inverters, shall support a Volt/VAr auto-regulation function. In this mode, the reactive power will be regulated by a curve of reactive power versus grid voltage automatically. The registers or setpoints for regulating System reactive power and PF will be both ignored by the inverter. definition/volt-var.txt Last modified: 2020/09/16 21:41(external edit)
