Performance of the distribution network by connecting solar and wind DGs

The operation of the distribution network (DN) is difficult due to the voltage stability when connecting multiple distributed generations. This paper explains the performance of a distribution network by connecting solar and wind Distributed Generation (DG). The distribution network is stable when the voltages are within the boundary limits. The voltage boundary limits are 0.95< 1 < 1.05 per unit. The voltages and power loss of the IEEE-85 and 25 bus radial distribution networks are evaluated by connecting Solar Distributed Generation (SDG) with variable power supply due to changes in the irradiation of solar panels. The voltages and power loss of the IEEE-85 bus distribution network are evaluated by connecting Wind-Distributed Generation (WDG) with variable power supply due to wind speed changes, and voltages and power loss are evaluated with load changes in the presence of WDG. By connecting both solar and wind-distributed generations, the voltages and power loss of the IEEE-85 bus DN are evaluated. The Multi-Objective Slime Mould Algorithm (MOSMA) is used to connect solar and wind DGs at optimal locations and sizes in the DN. The MOSMA has been applied to the IEEE-85 bus and 25 bus DN in MATLAB.
