Embodiment Construction

[0031] The present invention will be further described below in conjunction with drawings and embodiments.

[0032] Such as figure 1 As shown, the present invention proposes a microgrid reliability assessment method based on network invulnerability in microgrid reliability assessment. This method considers the microgrid safety criterion and operation constraints, and evaluates the global reliability index of the microgrid based on the network survivability obtained from the microgrid network structure. This index considers the ability of the entire network of the actual microgrid to maintain connectivity. In the field of power systems, survivability can be understood as the ability to maintain the connectivity of the network to the maximum extent when a certain fault or equipment maintenance occurs in the distribution network, so as to reduce the load loss during the fault process.

[0033] The fully connected network is the most compact network and the most invulnerable netw...

Abstract

The invention discloses a microgrid reliability evaluation method based on network survivability. According to the method, considering a microgrid safety criterion condition and an operation constraint, a reliability global index of the microgrid is evaluated according to the network survivability obtained via a microgrid network structure; and the capacity of maintaining connectivity of the wholenetwork of the actual microgrid is taken into consideration. In the field of electric power systems, the survivability can be understood to be when a distribution network breaks down or is overhauledby equipment, the communication performance of the network can be kept to the largest extent, so that the capacity of load loss in the fault process is reduced. The fully-communicated network is a network with the most compact structure and also is a network with the strongest survivability. According to the method, the survivability of the network is evaluated, and through the structural difference between the actual network and full-communication network of the corresponding number of nodes, evaluation is carried out by utilizing a network survivability index based on the equivalent shortest path number.

Description

technical field [0001] The invention relates to reliability evaluation of a micro-grid, which belongs to the field of smart micro-grids, and in particular to a method for evaluating the reliability of a micro-grid based on network invulnerability. technical background [0002] At present, the micro-grid system composed of distributed power sources and energy storage devices has developed rapidly and has become a new hotspot in the field of power system research. Due to the limitation of the current level of micro power supply manufacturing technology, the economic advantages of micro grids cannot be reflected. The advantages of improving the reliability of power supply are the main driving force to promote the research of micro grids. The existing reliability assessment of microgrids is mainly aimed at improving the reliability of microgrids after the introduction of microgrids, but there is a lack of relevant research on the reliability assessment of microgrids themselves. ...
