Problems solved by technology

[0008] 2) Sensitive load
[0009] 3) Strict load
[0023] In summary, traditional indicators do not take into account the timing and volatility of load and distributed generation, and do not involve the complexity of recovery control operations and sustainable support capabilities after recovery.

Embodiment Construction

[0071] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0072] The present invention provides a fault self-healing evaluation method of an urban comprehensive energy system, and provides the following new fault self-healing evaluation indicators:

[0073] (1) Self-healing recovery rate

[0074] The power supply recovery process after a distribution network fault starts from the occurrence of the fault and continues until the fault is completely cleared and the normal power supply of the entire network is restored. Therefore, during this period of time, the restoration of the load should be considered under the premise of taking into account the load importance level The total load recovery power is not the instantaneous power recovery value under the fault section; therefore, a self-healing recovery ratio index (self-healing recovery ratio, SHRR) is proposed around the recovery power and load ...

Abstract

The invention relates to a fault self-healing evaluation method for an urban integrated energy system. Novel fault self-healing evaluation indexes including the self-healing recovery rate, the self-healing recovery speed, the self-healing control operation complexity and the self-healing sustainable time coverage rate are provided, and a specific self-healing capability evaluation process is provided for the novel fault self-healing evaluation indexes. Risk assessment and self-healing reaction can be made in advance, and power supply of important loads is better guaranteed.

Description

technical field [0001] The invention belongs to the field of fault self-healing, and in particular relates to a fault self-healing evaluation method of an urban comprehensive energy system. Background technique [0002] The connectivity problem of the power system network is closely related to power production, power transmission, and power consumption, and reflects the strength of the network structure. The greater the connectivity of the power network, the stronger the ability to resist damage, and the higher the self-healing ability of the power grid. Therefore, the connectivity of the power grid is an important indicator to evaluate the self-healing degree of the power grid. [0003] The higher the connectivity of the network, the more the network can flexibly change the operation mode to achieve self-healing when a fault occurs. If the network after the fault is connected, it means that the network has a self-healing path. Therefore, this method can be used as the sta...
