Malaysia targets to become the second‐largest producer of solar photovoltaic (PV) in the world by increasing the current output from 12% to 20% in 2020. The government also expects to achieve 45% reduction of greenhouse gas emission by 2030 through renewable energy mainly by solar PV. Large‐scale solar (LSS) aims to produce 2.5 GW, which contributes to 10% of the nation's electricity demands. The LSS system is held back by the grid‐scale integration, transmission, and distribution infrastructure. Thus, power system analysis is crucial to achieve optimization in LSS to power grid integration. This paper investigates various power system analysis models and recommends an optimized configuration based on Malaysia's LSS scenario. In stage 1, an optimal PV sizing is carried out based on real data of LSS installation in different locations. In stage 2, power analysis is carried out using to analyze the potential difference variation when connected to a nine‐bus power system. The potential variation at each bus of the system is assessed and hence provides a feasibility statement on the most effective configurations for LSS–grid integration. This paper serves as the reference model for LSS–grid integration in Malaysia and is expected to be replicated in the other countries with similar conditions.

马来西亚大型太阳能项目评估：太阳能光伏并网电力系统分析。


马来西亚的目标是在2020年将目前的产量从12%增加到20%，成为世界第二大太阳能光伏（PV）生产国。政府还预计到2030年通过可再生能源实现温室气体排放量减少45%主要是太阳能光伏发电。大型太阳能 (LSS) 的目标是生产 2.5 吉瓦，满足全国电力需求的 10%。 LSS 系统受到电网规模集成、输电和配电基础设施的阻碍。因此，电力系统分析对于实现LSS优化至电网并网至关重要。本文研究了各种电力系统分析模型，并根据马来西亚的 LSS 场景推荐了优化配置。在第一阶段，根据不同地点 LSS 安装的真实数据进行最佳光伏尺寸调整。在第 2 阶段，进行功率分析，以分析连接到九总线电力系统时的电位差变化。评估系统每条总线的潜在变化，从而提供有关 LSS-电网集成最有效配置的可行性声明。本文作为马来西亚 LSS 与电网并网的参考模型，预计将在其他具有类似条件的国家进行复制。
