Abstract

The invention discloses a mixed sampling and minimum shedding load calculation-based reliability calculation method and platform. The calculation method mainly comprises three processes of extracting data, performing analysis and calculation on the data and outputting a power generation and transmission system reliability evaluation. The calculation platform comprises a data extraction module, a data analysis and calculation module and a power generation and transmission system reliability evaluation output module. According to the method and the platform, firstly the related data is extracted; secondly a component state of a power generation and transmission system is sampled, a minimum shedding load is solved, and each reliability index of the power system is analyzed and calculated; and finally the reliability of the power generation and transmission system is evaluated by analyzing and calculating each index, and a reliability evaluation result of the power generation and transmission system is output. The invention proposes a mixed sampling and minimum shedding load calculation-based reliability evaluation technology for the power generation and transmission system on the basis of being in close connection with engineering practice; and compared with the prior art, the mixed sampling and minimum shedding load calculation-based reliability evaluation technology can be used for remarkably improving the reliability evaluation efficiency of the power generation and transmission system on the basis of being in close connection with the engineering practice.

Description

technical field [0001] The invention relates to a power system reliability evaluation method, in particular to a power generation and transmission system reliability calculation method and platform based on mixed sampling and minimum load shedding calculation. Background technique [0002] The reliability assessment methods of power generation and transmission systems are mainly divided into analytical methods and simulation methods. Monte Carlo simulation simulates the state of each component in the system by generating random numbers, selects the system state by sampling, and obtains reliability indicators by statistical methods. Monte Carlo simulation is based on the characteristics of the probability model, which can reflect various random characteristics of the system, and obtain the expectation and variance of the reliability index and its probability distribution under various system states. The actual sampling times of the Monte Carlo simulation method are generally...
