Embodiment Construction
[0016] In order to further illustrate the power system economic dispatching method provided by the embodiment of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.
[0017] see figure 1 , the power system economic dispatching method provided by the embodiment of the present invention includes:
[0018] Step S100, decoupling the power system into a coordination center and multiple regions.
[0019] Step S200, according to the coordination center and multiple regions, establish a power system economic dispatch model, wherein the target of the power system economic dispatch model is the total power generation cost of conventional units in the power system within the dispatch time and the penalty cost of abandoning new energy generation load shedding Sum.
[0020] Step S300, decomposing the power system economic dispatch model into an interregional coordination model and multiple regional dispatch models, wherein the ...

The present invention discloses an electric system economical dispatching method, and relates to the electric system optimizing operation technology field. The reliability of the economical dispatching of the electric system is improved. The method comprises: decoupling the electric system into a coordination center and a plurality of areas; according to the coordination center and a plurality of areas, establishing an electric system economical dispatching model, wherein the target of the electric system economical dispatching model is the sum of the total cost of power production of a conventional power unit in the electric system and the discarding cost of the new energy power generation load shedding penalty; decomposing the electric system economical dispatching model into an inter-area coordination model and a plurality of area dispatching models, wherein the area dispatching models are in one-to-one correspondence with the areas, the inter-area coordination model corresponds to the coordination center, and the inter-area coordination model performs distributed optimization of the boundary nodes of each area; and calculating the economical dispatching result of the electric system according to the inter-area coordination model and the area dispatching models.
Description
technical field [0001] The invention relates to the technical field of power system optimization operation, in particular to a power system economic scheduling method. Background technique [0002] At present, the raising of energy and environmental issues has prompted the rapid development of new energy farms, such as wind farms, solar farms, and tidal farms. However, due to the large randomness and volatility of the new energy electric field, the power system incorporating the new energy electric field faces a more severe form, especially the economic dispatch of the electric power system faces greater challenges. [0003] The economic dispatching of the power system refers to dispatching the output of each unit in the power system under the premise of ensuring the safe and reliable operation of the power system and meeting the power quality and power consumption needs, so as to minimize the energy consumption and operating costs of the entire power system to get the maxi...
