Abstract
By virtue of the ability to vary local load via inverter (e.g., solar PV inverter) volt-ampere reactive power (VAR) injection, local demand and energy consumption can be controlled at a system level. Utilities that provide solar PV systems to consumers can leverage this ability to reduce the purchase of high cost energy. Moreover, revenue for such utilities can be maximized. For example, such localized voltage and VAR control allow for precise control to achieve, e.g., plus or minus about two percent of kW and kWHr of power consumed at a node.
