Problems solved by technology

The above accident reserve allocation method is simple and intuitive, and easy to implement. However, there is no one-to-one correspondence between the system emergency reserve capacity, system installed capacity, and system peak load. This method cannot well reflect the responsibility of each regional subsystem. The responsibility for accident reserve capacity does not take into account the characteristics of each regional power grid, the probability of accidents expected by each regional power grid, and the size of accident losses, etc.

Embodiment Construction

[0040] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0041] Such as figure 1 Shown, the present invention is divided into the following steps:

[0042] 1-1) Obtain the basic data of the interconnected power system, including the size of the total reserve capacity of the entire interconnected power system, internal generator data in each region (including the capacity of each unit, the forced outage rate of each unit, etc.), load data (including forecasted load , actual load, etc.), inter-regional connection section data (including the load of each component of the connection section, the forced outage rate of the connection line), etc.;

[0043] 1-2) According to the N-1 system safety operation criterion, consider the N-1 faults that lead to the system power shortage, and determine the expected accident set N c , and at the same time determine the probability of each accident;

[0044] 1-3) On t...

Abstract

The invention discloses a system accident reserve capacity coordination distribution method based on risk quantization, which belongs to the field of power system safe planning and operation. According to the invention, the accident probability in a region, the system reserve adjustment cost and the system outage loss are considered; consideration is given to the reserve configuration scheme risk quantization evaluation indexes of the system reliability and economy; quantization is carried out on accident reserve configuration and risk caused by insufficient configuration; and the system accident reserve capacity is shared according to the percentage of the accident reserve configuration risk index of each region in the risk index of the whole system. According to the invention, the probability of different accidents is discriminated; different requirements of different loads on the reliability are considered; and compared with the traditional accident reserve capacity distribution method, the system accident reserve capacity coordination distribution method based on risk quantization is more rational and scientific.

Description

technical field [0001] The invention belongs to the field of power system safety planning and operation, and more precisely, the invention relates to a method for coordinating and allocating system accident reserve capacity based on risk quantification. Background technique [0002] Power grid operation backup is an indispensable technical means to maintain the safe and stable operation of the power grid and ensure the safety and high-quality economic operation of the power grid. A certain amount of power reserves should be reserved during the operation of the power grid to cope with sudden changes in load, power grid failures, random outages of power generation equipment, etc., so as to minimize the adverse impact of the contradiction between power supply and demand on society and enterprises. Generally, the higher the ratio of reserve capacity to the total system load, the higher the power supply reliability of the system, but too much reserve capacity will cause low utili...
