Efficient Operative Cost Reduction in Distribution Grids Considering the Optimal Placement and Sizing of D-STATCOMs Using a Discrete-Continuous VSA

The problem of reactive power compensation in electric distribution networks is addressed this research paper from the point view combinatorial optimization using a new discrete-continuous version vortex search algorithm (DCVSA). To explore and exploit solution space, codification vector proposed, where discrete part determines nodes static compensator (D-STATCOM) will be installed, continuous optimal sizes D-STATCOMs. main advantage such that mixed-integer nonlinear programming model (MINLP) represents placement sizing D-STATCOMs only requires classical flow method to evaluate objective function, which implies it can implemented any language. function total costs grid losses annualized investment In addition, include impact daily load variations, active demand curves are included model. Numerical results two radial test feeders with 33 69 buses demonstrate proposed DCVSA solve MINLP best when compared solvers available GAMS software. All simulations MATLAB software its environment.
