Reduction of Annual Operational Costs in Power Systems through the Optimal Siting and Sizing of STATCOMs

The problem of the optimal siting and placement static compensates (STATCOMs) in power systems is addressed this paper from an exact mathematical optimization point view. A mixed-integer nonlinear programming model to present was developed with aim minimizing annual operating costs system, which sum energy losses installation STATCOMs. has constraints regarding active reactive balance equations those associated devices’ capabilities, among others. To characterize electrical behavior different load profiles such as residential, industrial, commercial are considered for a period 24 h operation. solution proposed reached general algebraic modeling system package. numerical results indicate positive effect dynamic injections on cost reduction. Pareto front built multi-objective studied when compared investment operative costs. complete validations made IEEE 24-, 33-, 69-bus systems, respectively.
