of smart inverters to contribute to voltage regulation. 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
Initially, smart inverters take charge of circuit voltage regulation. If these inverters reach their limits while attempting voltage regulation, legacy devices step in. During Stage-1, the primary goal is to bring the voltage within ANSI limits.
Abstract—The IEEE 1547 Standard for the interconnection of distributed energy resources (DERs) to distribution grids provisions that smart inverters could be implementing Volt/VAR control rules among other options. Such rules enable DERs to respond autonomously in response to time-varying grid loading conditions.
In this case, only conventional devices participate in the Volt/Var control. The control is purely based on local measurements (Short, 2004). The LTC and VR control settings are highlighted in Table 1. Table 1. Set points for legacy devices. Even though PV inverters are shown in Figure 4 they do not participate in the Volt/Var control.
