Abstract

Solar photovoltaic (PV) power, a highly promising renewable energy source, encounters challenges when integrated into smart grids. These challenges encompass voltage fluctuations, issues with voltage balance, and concerns related to power quality. This study aims to comprehensively analyze the implications of solar PV penetration in Malaysian power distribution networks predominantly found in urban and rural areas. To achieve this, we employed the OpenDSS 2022 and MATLAB 2022b software tools to conduct static power flow analyses, enabling us to assess the effects of solar PV integration over a wide area under two worst-case scenarios: peak-load and no-load periods. Our investigation considered voltage violations, power losses, and fault analysis relative to the power demand of each scenario, facilitating a comprehensive evaluation of the impacts. The findings of our study revealed crucial insights. We determined that the maximum allowable power for both urban and rural networks during no-load and peak-load situations is approximately 0.5 MW and 0.125 MW, respectively. Moreover, as the percentage of PV penetration increases, notable reductions in power losses are observed, indicating the potential benefits of higher smart grid PV integration.

智能电网太阳能城郊并网的对比分析

太阳能光伏发电作为一种极具发展前景的可再生能源，在接入智能电网时面临着诸多挑战。这些挑战包括电压波动、电压平衡问题以及与电能质量有关的问题。本研究旨在全面分析太阳能光伏渗透在马来西亚主要分布在城市和农村地区的配电网络中的影响。为了实现这一目标，我们使用OpenDSS 2022和MATLAB 2022b软件工具进行静态潮流分析，使我们能够在两种最坏情况下评估太阳能光伏集成在大范围内的影响:高峰负荷和空载期间。我们的调查考虑了电压违规、电力损失和与每种情况的电力需求相关的故障分析，从而促进了对影响的全面评估。我们的研究结果揭示了重要的见解。我们确定城市和农村电网在空载和峰载情况下的最大允许功率分别约为0.5 MW和0.125 MW。此外，随着光伏渗透率的增加，可以观察到电力损耗的显著减少，这表明更高的智能电网光伏整合的潜在好处。
