Chance-Constrained Optimization for Incremental Volt/Var Control in Distribution Networks with High Renewable Integration

The core message of this article is to design an incremental Volt/Var control scheme for distribution networks with high integration of inverter-interfaced distributed generation, such as photovoltaic systems. The control scheme is implemented by solving a chance-constrained optimization problem to minimize reactive power usage while maintaining voltages within safe limits sufficiently often.
