Evaluation of Distribution Network Operation State Based on Spark Parallel Computing

The distribution network is an important part of the power system. Timely and accurately assessing the operation state of the distribution network is the basis for ensuring the safe and stable operation of the distribution network. The characteristics of the distribution network, including wide geographical distribution, a great variety of equipment, complex network connections, the application of information and smart technologies in the distribution network, have promoted the exponential increase of various operation monitoring data from the distribution network. It brings difficulty to the dynamic evaluation of the operation state of the distribution network. This paper proposes to evaluate the operation state of the distribution network by using the analytic hierarchy process and the Delphi method together, meanwhile calculating the indicator of static data and dynamic operating data of the distribution network based on the Spark distributed parallel computing framework. As well as the distribution network operation state evaluation software system is developed to show the operation state of the distribution network in multiple granularities. The results have verified the flexibility, continuity and practicability of the system.
