Studies on Morphological Characteristics and Typical Power Supply Modes of Distribution Networks for New-Type Towns

With the constructions of new-type towns, power demand in the towns grows constantly. In this paper, we have analyzed new features of towns and power utilizations in the new circumstances, and promoted morphological characteristics of distribution networks for new-type towns. We have stated several indicators for the measurement of distribution networks for new-type towns as well as the influencing factors of optimizing operation for the networks. We have analyzed the quantized influences of network structures, equipment levels, automation levels, distributed powers and reactive compensations on the operation of distribution networks, and propose technical measures for the existing problems. With considerations of the influencing factors of power demands in new-type towns, we have computed the weight of each factor through Interpretative Structural Models (ISM) and Analytic Hierarchy Process (AHP), and concluded three power supply modes of the Industry-Oriented, the Commerce-Oriented and the Synthetic. Taking the Industry oriented power supply mode as an example, we have analyzed the requirements of networks, as well as the construction target, contents and configurations for the mode.
