Embodiment

[0105] Taking the joint power generation dispatching of cascade reservoirs from the lower reaches of the Jinsha River to the Three Gorges as an example, the joint dispatching model of cascade reservoirs and the optimal dispatching model of a single reservoir are established, and the compensation power of each reservoir is analyzed using the contribution coefficient calculation method based on the contribution value of compensation power. The power is redistributed, and the characteristic parameters of the four power stations in the cascade reservoir group are shown in Table 1.

Abstract

The invention discloses a cascade reservoir power generation scheduling compensation electric quantity distribution method. The invention belongs to the technical field of reservoir scheduling, the method comprises the following steps: respectively inputting runoff data of a design representative year into a reservoir single-reservoir optimization scheduling model and a cascade reservoir joint scheduling model, calculating the generating capacity of each reservoir during single-reservoir scheduling and joint scheduling of all reservoirs and the total generating capacity when a certain reservoir is runoff and the rest reservoirs are subjected to joint scheduling, and calculating compensation electric quantity and a relative contribution coefficient; calculating a relative contribution coefficient of each reservoir according to the compensation electric quantity contribution value of each reservoir; and according to the compensation electric quantity, the relative contribution coefficient and the power generation quantity of each reservoir during single-reservoir scheduling, updating the power generation quantity of each reservoir during joint scheduling of all reservoirs. Accordingto the method, the problem of distribution of cascade compensation electric quantity can be effectively guided, and the feasibility of joint scheduling is improved.

Description

technical field [0001] The invention belongs to the technical field of reservoir dispatching, and more specifically relates to a method for distributing power generation dispatching and compensating electricity of cascaded reservoirs. Background technique [0002] At present, with the successive completion of cascade reservoirs in various river basins, under the condition of the same number of reservoirs, the combined dispatch of cascade reservoirs has a larger total power generation than the output of single reservoir dispatch. Therefore, the combined operation of cascade reservoirs Scheduling has become the main research direction of reservoir dispatching. At the same time, the joint dispatching of cascade reservoirs is also vigorously promoted in China. [0003] Although the joint dispatching of cascade reservoirs can generate a certain amount of compensation power compared with single-reservoir dispatching (the difference between the total power generation of joint dispa...
