Optimal Integration of Photovoltaic Sources in Distribution Networks for Daily Energy Losses Minimization Using the Vortex Search Algorithm

This paper deals with the optimal siting and sizing problem of photovoltaic (PV) generators in electrical distribution networks considering daily load generation profiles. It proposes discrete-continuous version vortex search algorithm (DCVSA) to locate size PV sources where discrete part codification defines nodes. Renewable are installed these nodes, continuous section determines their sizes. In addition, through successive approximation power flow method, objective function optimization model is obtained. related minimization energy losses. method allows determining losses each period for renewable input provided by DCVSA (i.e., location sources). Numerical validations IEEE 33- 69-bus systems demonstrate that: (i) proposed finds global solution both test feeders when explored, peak scenario. (ii) case operative scenario, total reduction 23.3643% 24.3863%, respectively; (iii) presents a better numerical performance regarding value compared BONMIN solver GAMS software, which demonstrates effectiveness robustness master-slave algorithm.
