Locate the location and determine the optimal size of dispersed production resources and simultaneous parallel capacitors using the sine-cosine (SCA) algorithm in radial distribution systems

The usage of scattered sources of production and capacitor banks is increasing due to the development of distribution networks as well as increasing demand for electricity. Discontinued power plants and capacitors, if connected to a power grid in the right place, will have various effects, including loss reduction, improved voltage profiles, and increased network reliability. This dissertation is devoted to reducing losses of the distribution system to the simultaneous optimal location of distributed generation sources and capacitors in radial distribution systems. For this purpose, the sinus cosine algorithm (SCA), which is inspired by simple maths, is used. Simulation on the 69 IEEE bus interfaces. The simulation results show the efficiency of the proposed algorithm in the problem of optimal location of simultaneous distributed generation sources and capacitors in radial distribution systems to reduce losses and improve the voltage profile compared to other optimization algorithms used in this field.
