Research On Distribution Expanding Planning And Reconstruction Based On Recourse Utilization

Nowadays, the insufficiency of power supply is becoming the key factor to restrict national economy development. There is a growing extensive attention on how to instruct power investment with ideas of sustainable development, and how to arrange the plan, reconstruction, evaluation of power network. Based on the thoughts of power grid and energy efficiency improving, this paper completes the followed work:1. To solve the problem of power capacity shortage for regional load rise with the development of social economy, how to propose a reasonable scheme of distribution expansion planning and reconstruction is very crucial to the entire social benefits. As regional load rise, a novel method with the concept of insufficient capacity analysis, capacity-increase benefits and capacity-increase benefits ratio is presented to find the best investment scheme of disconnect switches and tie switches. The method which is feasible in economy and technology also enhances the power network reliability. According to a practical example, the method presented in this paper is proved helpful and feasible in distribution expansion planning and reconstruction.2.This paper presented the guidance to power network plan and reconstruction with DSM technology, which altered the traditional idea to satisfy the increasing energy need with increasing energy supply purely, and construct a concept of demand side save as a replaceable recourse of supply side. With DSM, a better social benefits and a more economy mode could be reached for the purpose of energy service.3.To improve the insufficiency of power supply capability evaluation and decision-making ability for distribution reconstruction, a practical distribution comprehensive evaluation system is developed. Based on Three-Tier architecture, the designing idea and concept of the system is also presented. Combined with the theory of B/S, the system is researched deeply and is applied in a real engineering project using ASP program language and large-scale commercial database Oracle. By means of inner data analysis in power utility, the system can carry out guidance significance. The practical case shows that this software is an effective and feasible tool for solving distribution extending planning and reconstruction problems.
