Distribution System Reliability Calculation Method Considering Randomness of Demand Side Resource Response

Abstract

The invention relates to a method for calculating the time-varying reliability of a power distribution system considering the randomness of demand-side resource response, comprising the following steps: Step 1. Establishing physical models of different demand-side resources according to the physical characteristics of the demand-side resources; Step 2 1. Considering the random failure of demand-side resource equipment, establish a response volume model for different demand-side resources; step 3, calculate the response volume after aggregation of demand-side resources; step 4, establish a response volume model after aggregation of demand-side resources considering random processes , to obtain the probability of the demand-side resource response in different states; step 5, calculate the time-varying reliability value of the distribution system considering the randomness of the demand-side resource response. The invention can accurately and quantitatively evaluate the influence of the demand-side resource response randomness on the reliability of the power distribution system.

Description

technical field [0001] The invention belongs to the technical field of power distribution system reliability analysis, and relates to a power distribution system reliability calculation method, in particular to a power distribution system reliability calculation method considering the randomness of demand-side resource response. Background technique [0002] With the development of information and communication technology, demand-side resources such as energy storage equipment, distributed power generation equipment, etc., can provide response to the power system, improve the ability to optimize the allocation of system resources, and thus improve the ability of the system to operate safely and reliably. Therefore, it is very important to quantitatively evaluate the ability of demand-side resources to provide response, and then evaluate the distribution system reliability calculation considering demand-side resources. [0003] However, different types of demand-side resource...
