摘要

近年来,电力需求的增长导致可再生能源(RES)并网的增加。事实证明,这对电力系统和环境影响都是有利的。事实证明,可再生能源的引入有效地减少了因电力短缺而造成的停电。随后,这项技术在保护大气方面取得了成效。然而,可再生能源的整合给电网带来了挑战。本文分析了故障条件下风力发电机组并网的效果。从所获得的结果来看,连接RES增加了故障电流,这反过来又有可能增加电网内部的破坏。

Analysis of power systems faults with the integration of renewable energy sources
Recently the growing demand for electricity has led to the increase of integrating renewable energy sources (RES) into the grid. This has proven to be an advantage for both power systems and environmental impacts. The introduction of RES has proven to be effective in minimizing power outages due to electricity shortage. Subsequently, this technology has been effective in preserving the atmosphere. However, RES integration has challenges which they bring into the power grid. In this paper, we analyzed the effect of connecting the wind turbine into the grid under fault conditions. From the results obtained, connecting RES increases the fault current which in-turn has the potential to increase the damages within the power grid.
