Reduction in System Losses and Power Demand by Combination of Optimal Power Flow and Conservation Voltage Reduction Using Smart PV Inverters

This paper presents a new control methodology of smart PV inverters that combines Optimum Power Flow (OPF) and Conservation Voltage Reduction (CVR) in a single step for reduction of system active power demand as well as active power losses in distribution systems. The methodology has been implemented in two different types of distribution systems simulated in PSS®E. The study also underscores the added benefits pertaining to active power demand reduction, that can be extracted out of PV systems in addition to their primary function of real power generation.
