Since the significant amount of grid establishment and grid renovation, which brought more instances of power outages, it is necessary to consider efficient management of an outage plan, ensuring all kinds of outages could be done safely and efficiently. There are still problems for the dispatching department to deal with the outage repetition, long duration on outages and outage restoration rate. Thus, dispatching decision-making rules based on annual outage plan intelligent arrangement and equilibrium optimization are proposed, which considers the demand for utilizing closed-loop control on the outage plan, and can analyze the flexible modeling optimization core, intelligently optimize outage plan, ensure the outage plan execution, and increase the outage plan success rate based on outage rule constraints. The case study is done based on a provincial grid data in China, which verifies the efficiency of the model.

Recently, with the rising proportion of new energy installed capacity in China, the problem of new energy consumption in the northwest region is particularly prominent, and the phenomenon of abandoning wind power and solar power is serious. In order to alleviate this situation, this paper proposes an annual maintenance plan optimization method for new energy consumption. Under the premise of considering the new energy output, the goal is to minimize the limited power of new energy generation and the minimum cost of maintenance. Transmission maintenance planning model is mixed integer linear programming model and can be solved by a solver such as CPLEX. The feasibility of the method is verified by a provincial power grid example, which effectively reduces the limited power of new energy generation.
