Grid-connected New Energy Generation and its Influence on Power Supply Quality based on Smart Grid

With the large-scale access of NE(new energy) sources, the PS(power system) has presented a new pattern of multi-source coordinated and complementary PG(power generation), but the existing capacity benefit and absorptive capacity evaluation methods have not considered the impact of the coordinated operation of wind, solar, water and fire power sources on the time series load curve, and there is also a lack of a NE grid-connected capacity benefit and absorptive capacity evaluation method that can take into account the generation output characteristics of various types of power sources and multi-energy complementary characteristics. This paper analyzes the problems existing in traditional research, and analyzes the impact of NEG(new energy generation) on power supply quality based on smart grid. In addition, the capacity benefit and absorptive capacity evaluation methods of large-scale NE grid-connected are deeply studied in this paper, and some innovative research results have been obtained. Therefore, the method proposed in this paper can be used to promote smart grid to have a positive impact on power supply quality.
