Abstract

Reactive power optimization is important to power system stability and power quality. How to use the reactive power control method to improve the voltage level and decrease system loss is of value both in theory and application. The adjustment of generator voltages, transformer taps, shunt capacitors and inductors will control the reactive power distribution and affect voltage profiles and power losses. The objective is to find proper adjustments of these control variables that would maintain acceptable voltage profiles and minimize power losses. Reactive power optimization has commonly been formulated as a complicated constrained optimization problem with non-differentiable nonlinear objective function Reactive Power consumption increases losses in the system, which reduces the total system real power. Optimizing reactive power in the system can minimize total system real power loss. This can be done by optimally setting the terminal voltage of generating plant, transformer tap settings, output of compensating devices such as capacitor bank and synchronous condensers. Conventional Optimal Reactive Power Dispatch (ORPD) formulations utilize minimization of total system real power loss or voltage deviation as an objective to compute optimal settings of reactive power output or terminal voltage of generating plants, transformer tap settings and output of compensating devices. The present work has considered the setting of Flexible AC Transmission System (FACTS) devices as additional control parameters in the ORPD formulation and studies its impact on system loss minimization. Static models of FACTS devices consisting Static VAR Compensator (SVC) have been included in the present ORPD formulation.
