Power transmission network frame recovery method based on multi-agent and thermal power generating unit cluster simulation

Abstract

The invention discloses a power transmission network frame recovery method based on multi-agent and thermal power generating unit cluster simulation, and the method comprises the steps: judging a fault type according to the obtained state information of a power transmission network frame in an abnormal state of the power transmission network frame, and positioning a fault point; and constructing a power transmission network frame recovery scheme according to the fault type and the fault point, scheduling each agent and the thermal power generating unit in the power transmission network frame simulation model to perform simulation recovery according to the power transmission network frame recovery scheme, and determining an optimal power transmission network frame recovery scheme according to state information of simulation recovery. In the abnormal state of the power transmission network frame, the fault type is analyzed, a specific fault point is positioned, a recovery scheme can be better determined, and meanwhile the effectiveness and feasibility of the scheme are determined according to analogue simulation of the recovery scheme.

Description

technical field [0001] The invention relates to the technical field of power system security defense and recovery control, in particular to a transmission grid recovery method based on multi-agent and thermal power unit cluster simulation. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Many large-scale power outages occurred in the world in recent years fully demonstrate that: under the background of the strengthening of the power system structure and the gradual improvement of the monitoring and control level, large-scale blackouts are still a serious threat to the modern power system. As one of the important measures of power system security defense, it is of great significance to study the rapid recovery of local isolated systems after blackouts to reduce the economic losses and social unrest caused by accidents. [0004] The goal of ...

Problems solved by technology

[0005] Since the existing methods only focus on the optimization strategy of the restoration of the transmission grid, and are not combined with the actual restoration process, especially the response process of the recovery of thermal power units and the switching operation process of the substation, which account for a relatively high proportion of the power system, are not involved. The obtained parameters such as recovery time and recovery power generation cannot reflect the actual effect after the strategy is implemented, and it is difficult to effectively guide the specific process of grid recovery based on the optimization strategy

[0006] Through the above analysis, the inventor believes that the existing problems and defects of the existing technology are: the existing recovery method cannot simulate the recovery scheme, and at the same time, there is no platform capable of monitoring, fault judgment and analysis of the transmission grid in the prior art
