Abstract

The invention discloses an active power distribution network information physical system reliability calculation method, which comprises the following steps: sampling by adopting sequential and non-sequential Monte Carlo simulation methods based on information link validity; performing equivalence by using a power distribution network upward equivalence algorithm; and calculating the reliability of the information physical system of the active power distribution network through an analytical algorithm. By analyzing the interactive influence of information and a physical system, an information system reliability model which is based on the hybrid communication network and considers routing transfer and complex fault factors is established, the contribution of distributed energy in fault recovery is considered, the influence of information element failure on the reliability of the active power distribution network is analyzed, the reliability evaluation method of the information physical system of the active power distribution network is provided, and effective technical support is provided for planning and operation of the active power distribution network.

Description

technical field [0001] The invention relates to a distribution network reliability evaluation method, in particular to an evaluation method for the reliability of an active distribution network information physical system. Background technique [0002] The large-scale grid-connection of distributed renewable energy has changed the operating characteristics of the distribution network, and at the same time deteriorated the power quality and economical operation of the grid. In this context, the concept of "Active Distribution Network (ADN)" was proposed in the 2008 International Conference on Large Power Grids. The active distribution network monitors the operating status in real time and adopts various control methods to avoid the deterioration of the status. Further improve grid performance while improving energy efficiency. The implementation of active management is inseparable from Information and Communication Technologies (ICT). The timely and accurate transmission and...
