Studying Connection Mode Of High Voltage Distribution Networks Based On Improved AHP

High voltage distribution network is an important component of power system, which is a cohesive tie between transmission network and medium voltage distribution network. Connection mode plays an important role in high-voltage distribution network planning. It is not only economic and reliable to the power grids, but also significant to the whole electric power industry. This paper first study many kinds of connection modes of high voltage distribution network and summary every kinds of connection modes'applicable region. Secondly, this paper establishes appraisal system of connection modes and introduces the computational method of evaluating index from four aspects. Thirdly, this paper presents an integrative evaluation method based on IAHP and expert-group dicision, which can be used to evaluate the connection mode of high voltage distribution network. At last, a whole process of this method is illustrated with an example and the example proves the feasibility and effectiveness of the proposed method.
