Conservation Voltage Reduction and Volt-VAR Optimization: Measurement and Verification Benchmarking

Integrated Volt-VAR Regulation/Optimization

Before diving into integrated volt-VAR optimization, it is important to understand the concept of VAR. VAR stands for Volt-Amps Reactive and is the measuring unit for reactive power, which is created by energizing transformers and powering motors, pumps, air conditioners, and other similar devices [2]. These electric appliances have large coils and magnets inside them and require both real and ...

Photovoltaic Impact Assessment of Smart Inverter Volt-VAR Control on Distribution System Conservation Voltage Reduction and Power Quality

Experimental Distribution Circuit Voltage Regulation using DER Power Factor, Volt-Var, and Extremum Seeking Control Methods

With the rapidly increasing number of distributed energy resources (DER) on electric grids worldwide, there is a growing need to have these devices provide grid services and contribute to voltage and frequency regulation. PV inverters and other reactive-power capable DER have the capability to minimize distribution losses and provide voltage regulation with grid-support functions such as volt-v...

State Estimation and Volt-Var Control in Smart Distribution Grid

Distribution smart grid is very important part of the smart grid. Utilities use Distribution Management System (DMS) as supervisory control layer at the power system control centers. State Estimation (SE) and Volt-Var Control (VVC) are the prime applications of the DMS. In the modern DMS, SE is required for extensive monitoring and control of the entire distribution network. In the presence of ...

Volt/var Control in Distribution Systems as a Multiobjective Optimization Problem

⎯ The integrated control of voltage and reactive power (volt/var) on radial distribution feeder is formulated as a multiobjective optimization problem to be solved trough the Strength Pareto Evolutionary Algorithm (SPEA2), a relatively recent technique of recognized computational efficiency. Two objectives has been established: voltage level variation and power and energy losses including costs...
