Abstract

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.

连接太阳能和风能 DG 的配电网络性能

当连接多个分布式发电设备时，配电网（DN）的运行会因电压稳定性问题而变得困难。本文解释了连接太阳能和风能分布式发电（DG）的配电网络的性能。当电压在边界限制内时，配电网络是稳定的。电压边界限制为每单位 0.95< 1 < 1.05。通过连接太阳能分布式发电 (SDG)，评估了 IEEE-85 和 25 总线径向配电网络的电压和功率损耗。通过连接风力分布式发电（WDG），评估了 IEEE-85 母线配电网络的电压和功率损耗，风力分布式发电会因风速变化而改变供电，在 WDG 存在的情况下，评估了负荷变化时的电压和功率损耗。通过同时连接太阳能发电和风力分布式发电，对 IEEE-85 总线 DN 的电压和功率损耗进行了评估。多目标黏模算法（MOSMA）用于在 DN 的最佳位置和大小连接太阳能和风能分布式发电设备。MOSMA 已在 MATLAB 中应用于 IEEE-85 总线和 25 总线 DN。
