Problems solved by technology

However, the participation of demand-side resources in power grid operation will bring a series of problems to the safe and reliable operation of the system
For example, once the information and communication system under hierarchical and decentralized control fails, it will make it difficult for the demand-side resources in the control area to participate in demand response, thus affecting the reliability of system operation

Abstract

The invention relates to a power distribution system reliability calculation method considering demand side resource hierarchical decentralized control. The method comprises the following steps: step1, establishing a fan output multi-state model and a fan fault two-state model which respectively consider wind speed randomness and fan fault uncertainty; step 2, establishing a distributed wind power multi-state reliability model containing a plurality of fans; 3, establishing an information communication system reliability model of hierarchical decentralized control considering random faults and information delay; step 4, establishing a demand side resource reliability model considering hierarchical decentralized control; and step 5, calculating a reliability value of the power distributionsystem considering demand side load hierarchical decentralized control, and obtaining a reliability analysis result of the power distribution system. According to the invention, the reliability of the power distribution system considering demand side resource hierarchical decentralized control can be accurately calculated.

Description

technical field [0001] The invention belongs to the technical field of power system reliability assessment, and relates to a reliability calculation method of a power distribution system, in particular to a reliability calculation method of a power distribution system considering hierarchical and decentralized control of resources on the demand side. Background technique [0002] Distributed power generation and demand-side loads in smart grids, such as the development of smart devices such as electric vehicles and air conditioners, and the penetration of information and communication technologies, provide demand-side resources, including distributed generator demand-side loads, to participate in power system operations. conditions. However, the participation of demand-side resources in power grid operation will bring a series of problems to the safe and reliable operation of the system. For example, once the information and communication system with hierarchical and decent...
