Problems solved by technology

[0005] In order to achieve a coordinated balance between cost and reliability benefit, it is necessary to construct a cost and reliability benefit model. At present, there are many existing technologies for the cost-benefit of a single reliability improvement measure, but they do not consider the cost and reliability benefit in multiple improvements. A Method for Optimal Allocation Among Reliability Measures

Abstract

The invention provides a configuration scheme optimization method and system for a power distribution network. The method comprises the following steps: establishing a power distribution network costbenefit model; establishing a power distribution network reliability benefit model; obtaining a configuration scheme set of the power distribution network based on the configuration schemes of the grid structure, power distribution automation and hot-line work; performing reliability analysis on the configuration scheme set of the power distribution network by using a sequential Monte Carlo and fault consequence analysis method based on the reliability benefit model of the power distribution network to obtain a reliability index; calculating the whole life cycle cost of a configuration schemeset of the power distribution network based on the power distribution network cost benefit model; and according to the reliability index and the full life cycle cost of the configuration scheme set, determining a power distribution network configuration scheme which satisfies the reliability index and has the minimum full life cycle cost. According to the invention, the scheme with the lowest fulllife cycle cost meeting the reliability index can be obtained, the asset utilization rate is improved, the enterprise production cost is reduced, and the power distribution network operation has highfeasibility.

Description

technical field [0001] The invention belongs to the technical field of power system distribution network automation, and in particular relates to a configuration scheme optimization method and system for distribution network Background technique [0002] Reliability and economy have always been the two most important indicators of the power system, and they are a comprehensive reflection of the planning, construction, operation and management capabilities of the power grid. [0003] Since the current domestic distribution network is mostly based on segmented management, and a comprehensive reliability mechanism has not yet been formed, in order to ensure reliability, the distribution network has invested a lot of money in automation, rapid maintenance, and network structure optimization. How to ensure these It is an urgent problem to study and solve at present that the investment should give full play to its due benefits so as to achieve the optimal balance between reliabili...
