Efficient Integration of Fixed-Step Capacitor Banks and D-STATCOMs in Radial and Meshed Distribution Networks Considering Daily Operation Curves

The problem regarding the optimal integration of efficient reactive power compensation in radial and meshed distribution networks using fixed-step capacitor banks static compensators (D-STATCOMs) is addressed this research paper by proposing a master–slave optimization methodology. Radial topologies are considered for grid structure while including variable active demand curves. An economic analysis performed, considering net present value plan, as well costs energy losses banks’ acquisition, installation, operation. In case D-STATCOMs, an annualized presented. master stage, discrete version generalized normal (GNDO) algorithm selects nodes sizes banks. slave successive approximations flow approach implemented. Numerical results IEEE 33-bus (with both topologies) 85-bus configuration) demonstrated proposed optimization’s effectiveness minimizing project’s expected planning period five years. Moreover, simulation 69-bus under peak operation conditions showed that GNDO excellent technique to solve studied when compared combinatorial exact methods. addition, numerical validations D-STATCOMs confirmed robustness addressing problems associated with medium-voltage systems.
