Abstract

The invention discloses a method and a system for unit recovery sequence optimization taking into account multi-infeed DC participation. According to the DC starting characteristics, the stability index representing the impact degree of the DC starting on a receiving end power network is determined. According to the above stability index, the optimization model of generator restoration sequence considering multi-HVDC participation is established. Genetic algorithm with elite strategy and non-dominated ranking is used to solve the model. According to the result, the order of unit recovery is obtained. The method can effectively avoid the problem of system security degradation caused by only pursuing recovery efficiency in the startup process of multi-HVDC units.

Description

technical field [0001] The invention relates to the field of electric technology, in particular to a method and system for optimizing the restoration sequence of a unit taking into account the participation of multi-infeed direct current. Background technique [0002] In the process of network structure reconstruction after a major power outage, black-start units, live islands and nearby live systems connected by lines can effectively support the network structure reconstruction in the power outage area, and lay the foundation for subsequent load recovery. Optimizing power recovery has great practical significance. [0003] In recent years, with the development of power technology, high voltage direct current transmission (HVDC) technology has been widely used in long-distance and large-capacity power transmission due to its good economy and controllability. So far, the continuous construction of DC lines has led to the formation of a large-scale multi-infeed DC receiving e...
