Embodiment Construction

[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0037] like figure 1 , the power system safety characteristics include power system stability characteristics and event synthesis characteristics, the event synthesis characteristics include event occurrence probability characteristics, event process characteristics and event consequence characteristics, and the event process characteristics include power system transient transition process characteristics, chain reaction Process characteristics and handling characteristics.

[0038] Power system security assessment is divided into grid operation security assessment and grid planning security assessment according to its purpose. The power grid operation security assessment is based on the current operating status of the power grid, and evaluates the risk of power outage events in the next 10 to 20 minutes; the power grid planning security assessment is aimed...

Abstract

The invention provides a safety assessment method for intermittent power high-permeability power network planning. The method includes the steps of selecting a scheme I; analyzing stability of a typical operation mode; selecting a power system operation state and analyzing the same; and assessing safety of power network planning. Facility stabilizing cost and power failure risk loss are included in comprehensive annual cost of the power network planning scheme, and safety and economy of the scheme are comprehensively compared and selected.

Description

technical field [0001] The invention belongs to the field of power systems, and in particular relates to a safety evaluation method for intermittent power supply high-penetration grid planning. Background technique [0002] The ratio of the installed capacity of the intermittent power supply to the peak load of the grid is called the capacity penetration rate of the intermittent power supply, and the capacity penetration rate of the intermittent power supply is also called the penetration rate. Intermittent power supply access will have various impacts on the power grid. As the penetration rate of intermittent power sources in the power grid increases, the impact on the power grid will also increase accordingly. Judging from the occurrence process of major blackouts at home and abroad, some major blackouts are closely related to the state of power generation capacity reduction before the power grid failure. At present, there is no set of methods for risk assessment for the ...
