An Evaluation System to Reactive Power Operation in LV Distribution Network Based on Big Data
摘要
Abstract
Existing management for reactive power operation in LV distribution network in China is lack of uniform and targeted standards mainly due to complexity of reactive power compensating strategy and dispersion of reactive compensation equipment. Therefore a new evaluation system was proposed in this paper. Based on big data technology, there were three layers in this new evaluation system for reactive power operation, i.e. data, index and application layers. The proposed system could fully explore potential value of big data in evaluation work of LV distribution network. In order to avoid fuzziness and overlap of evaluation objectives, concept of single grid cell was introduced into the system. With this division principle of target object, evaluation system finally realized horizontal comparison of all LV distribution network grid cells. The proposed evaluation system was applied to assess reactive power operation in a regional distribution network, and result verified correctness and reasonableness of this system. The proposed evaluation system can be available for refined management of reactive power operation in LV distribution network and increases value of data assets in smart gird, assuring all actual evaluation requirements in LV distribution network satisfied more scientifically and subtly.关键词
