Embodiment Construction
[0114] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0115] The present invention introduces a two-stage decision-making idea, and tries to use the runoff forecast information with a limited forecast period and forecast accuracy to establish a two-stage stochastic optimal dispatch model that can guide the rolling update of medium and long-term power generation plans.
[0116] Such as figure 1 As shown, a two-stage stochastic optimal scheduling method for hydropower station reservoirs based on the approximation of the residual period benefit function mainly includes the following steps:
[0117] (1) Introduce the idea of two-stage decision-making, divide the dispatching period of the hydropower station reservoir into the current stage and the remaining period, and construct a two-stage decision-making model framework.
[0118] The scheduling period of the hydropower ...
