Problems solved by technology

[0004] The existing actual maintenance and outage planning strategy relies on the experience and subjective judgment of decision makers, and is only suitable for the maintenance decision arrangement for a single outage event, but it is difficult to achieve the optimal decision for the maintenance decision arrangement for multiple outage events, and the optimization model lacks the power grid The comprehensive consideration of the maintenance side, the user side, and the maintenance side has resulted in the failure of the maintenance plan to guarantee the minimum user outage power and the highest user satisfaction, and the formulation process of the power outage plan is cumbersome and cannot achieve the global optimum. It is urgent to propose an artificial intelligence-based and multi-objective constrained outage plan automatic orchestration method to solve the decision-making problem of power grid maintenance plan for multiple outage events

Abstract

The invention relates to a comprehensive power-cut plan arrangement method, which comprises the following steps of: obtaining at least one alternative outage line power-cut plan; serving a node voltage phase angle added at the head node of the alternative outage line as a state variable, and constructing a mixed integer quadratic programming model with all linear constraint conditions; constructing a target function according to the power-cut plan target; and optimizing the model, and carrying out iterative security check. Optimization and adjustment of the power-cut plan can be effectively realized, and a result satisfying N-1 security constraints and other anticipated fault constraints is provided. Powerful support can be provided for power grid operation mode arrangement under the conditions of limited power failure windows and relatively large power failure demand.

Description

technical field [0001] The invention relates to the technical field of power system outage decision-making, in particular to a comprehensive outage planning method. Background technique [0002] With the development of science and technology and the progress of society, people's requirements for power and power quality are also increasing day by day. Therefore, there is a grid power outage plan for the purpose of grid daily maintenance and grid maintenance. In order to prevent large-scale power outages caused by accidents in the power grid, and reduce the inconvenience caused by power grid failures to people's daily life. [0003] The outage arrangement of power transmission and transformation equipment is a complex optimization problem, which needs to balance the goals of power supply adequacy, safety, and economic cost, and also needs to comprehensively consider different requirements such as synergy, mutual exclusion, and time window of outage arrangement. [0004] The ...
