Abstract

The increase of distributed generation (DG) is now clearly significant in many countries as in Mexico. Photovoltaic systems (PV) arc the most popular, due the flexibility and simple installation. As it is known, PS' uses electronic power converters to adapt and get the necessary features as power sour-ce. Typically, PV converters produce certain implicit harmonic distortion current level due to the power electronics components. Therefore, additional considerations must be taken into account on typical distribution networks analysis. This paper shows the main effects of PV systems in a typical mexican radial network. Cases were adapted to approach the most symbolic and relevant technical and operational aspects. Maximum PV generation and minimum load conditions are considered as main operational states. Operational technical limits are taken also into account. Electrical parameters such as ener losses, power factor (PF), voltage regulation (VR) and voltage total harmonic distortion (THD) are analyzed in this context. Impact level is estimated in function of operational technical limits and electrical parameters.

光伏渗透对墨西哥中压配电网的影响研究

分布式发电(DG)的增长现在在许多国家都很明显，比如墨西哥。光伏系统(PV)是最受欢迎的，由于灵活性和安装简单。众所周知，PS使用电子电源转换器来适应并获得必要的功能作为电源。通常，由于电力电子元件的影响，光伏变流器会产生一定的隐式谐波失真电流水平。因此，在典型的配电网分析中，必须考虑到额外的考虑。本文分析了典型的墨西哥径向电网中光伏系统的主要影响。对案例进行了调整，以接近最具象征意义和相关的技术和操作方面。考虑最大光伏发电和最小负荷工况为主要运行状态。还考虑到操作技术限制。在此背景下，分析了电能损耗、功率因数(PF)、电压调节(VR)和电压总谐波失真(THD)等电气参数。影响等级是根据操作技术限制和电气参数来估计的。
