Improved Real-Power Loss Minimisation
Abstract
The problem of the reactive control of a power system is formulated as a static optimisation technique to ensure the minimisation of the real-power system losses by controlling the switchable reactive power sources, generator terminal voltages, transformer tap ratios and phase shiftet's. The objective function as well as the constraints are established using the linearized sensitivity relationships of power system state and control variables and standard linear programming routines are used to determine the optimum operating condition; the fast-decoupled load flow technique is employed because it is fast, simple and has less computer storage. Results of the application of this development to the IEEE 14 bus system is presented.
