Abstract

This article presents the load flow study of Unand feeder with addition of photovoltaic (PV) system. Power flow analysis is needed in the feasibility study of the PV system installation. In this study 300 kW solar power capacity was selected in the simulation of power flow analysis to evaluate the best system states. The results of the study using four cases show that the best voltage profile is obtained in conditions where the PV system is placed on the bus which have lowest voltage and on the load bus which farthest from the source. All load bus voltages have increase above 0.9 p.u in this case and and the lowest voltage within SPLN standard. The lowest level of losses of 55.429 kW is obtained in case three where PV is placed only on buses with the lowest voltage value. Power losses are obtained far below 10% as the losses permitted according to the PLN standard. Therefore, The integration of PV system into an Unand distribution network can improve the voltage profile and reduce total system losses.

Andalas大学配电系统光伏系统集成的潮流分析

本文研究了光伏系统加入后的无电馈线负荷流。在光伏系统安装可行性研究中，需要进行潮流分析。本研究选取300 kW的太阳能发电容量进行潮流分析仿真，评估系统的最佳状态。通过四个实例的研究结果表明，光伏系统在电压最低的母线和离电源最远的负载母线上的电压分布最佳。在这种情况下，所有负载母线电压都增加到0.9 p.u以上，并且是SPLN标准内的最低电压。在情况三中，PV仅放置在具有最低电压值的母线上，获得了55.429 kW的最低损失水平。功率损耗远低于10%，根据PLN标准允许的损耗。因此，将光伏系统集成到Unand配电网中可以改善电压分布，降低系统总损耗。
