Embodiment Construction

[0080] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0081] The step flow chart of the present invention is as figure 1 Shown, the structural diagram of the present invention is as figure 2 As shown, the specific implementation steps are as follows:

[0082] (1) Step 1: Internal optimization of regional associations.

[0083] Multiple independent areas are combined to form a regional federation to share the remaining power. The optimization of the internal power sharing of the regional federation is based on the call of controllable elements and the output of uncontrollable elements, and the optimization is based on hours. Time scale, a total of 24 optimization periods. In optimization, make full use of the power exchange between different regions and the flexible adjustment capability of...

Abstract

The invention discloses a regional complex two-stage economic dispatching method considering water-light-storage complementation. The method comprises the following steps: combining a plurality of regions which comprises a solar power station, a pumped storage power station, an interruptible load and a transferable load into a regional complex; constructing an internal optimization function of theregional complex, and obtaining a decision result of the regional complex through the optimization function; optimizing the decision model through the scheduling center according to the decision result of the regional complex to obtain a scheduling decision result of the scheduling center; according to the decision result of the regional complex and the scheduling decision result of the scheduling center, determining the calling of controllable elements in the regional complex and the transaction condition between the regional complex and the outside; and determining a scheduling strategy ofthe scheduling center according to the calling of the controllable elements in the regional combination body and the transaction condition of the regional combination body and the outside to obtain ascheduling plan. According to the invention, the cost of the regional combination body is reduced, the absorption capability of the water-light storage system for new energy is improved, and the source electricity quality is improved at the same time.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a two-stage economic scheduling method for regional associations considering the complementarity of water, photovoltaics and storage. Background technique [0002] The promulgation of Document No. 9 of Xindiangai has led to the emergence of a large number of social capital that directly participates in the electricity sales business through qualified distributed power sources. With the implementation of the global sustainable development strategy, photovoltaic power generation and cascade hydropower have received strong support from the state and the government, and their proportion in the active distribution network has increased year by year. However, the fluctuation and randomness of photovoltaic power generation and cascade water supply It also causes a large amount of light and water abandonment. The high proportion of clean energy connected to the grid has brought great ch...
