Platform Building for Wide-Area Spatiotemporal Sequences Analysis of Large-Scale Power Grid Based on Spark

To address the energy internet trends and increasingly complex operating environment, we need to enhance the mining depth and utilization capability of energy internet multi-source data relying on big data technology. First, in the view of the wide-area spatiotemporal sequences data of large power grid, this paper expounds the Spark's advantages in distributed computing and the goal of big data platform, designs the big data platform architecture of power grid based on Spark, and describes each level of the platform in detail. Secondly, this paper describes the Spark's advantage in processing the spatiotemporal sequences data. Finally, on the basis of Spark and Hadoop experiment environment, this paper carries out typical clustering algorithm to compare the performance between Spark and Hadoop. The results verifies that Spark has a great advantage in data processing comparing with Hadoop MapReduce, which lays the foundation for the next step research.
