[0023] The above-mentioned patents [1-15] basically focus on the operation side of cascade hydropower stations, focusing on the coordination and dispatching of cascade hydropower stations; patents [16-19] focus on the power market side, focusing on how upstream and downstream hydropower stations participate in the power market competition and the determination of clearing prices; although the patent [20-21] involves grid planning, the patent [20-21] is mainly aimed at the planning method of the precise distribution network. Balanced large-scale coordinated planning issues have not been covered, let alone the analysis of the long-term dynamic process of the construction of leading reservoirs, and the establishment of a suitable evaluation plan and evaluation system

The invention discloses a method for optimizing the operation of a hydropower cluster in a leading reservoir considering market transactions, belonging to the field of hydropower cluster dispatching, taking into account the power generation capacity of the hydropower cluster, forecasting of incoming water, load forecasting, forecasting of power generation plans, and section restrictions, combined with the balance of electricity and electricity in the province As a result, for each inter-regional UHV DC channel, the power and quantity planned for the power transmission agreement were planned and designed respectively, and the annual plan for cross-regional water, fire, wind, wind and drought mutual aid was arranged, and the power and quantity sent out by the national grid dispatching unit were arranged. , Inter-governmental agreement electricity, formed a comprehensive hydropower cluster annual power transmission plan within the province and across provinces and regions considering market transactions.
Description
technical field [0001] The invention belongs to the field of hydropower cluster dispatching, and relates to a method for optimizing the operation of a leading reservoir hydropower cluster considering market transactions. Background technique [0002] At present, domestic research on cascade hydropower has been initially carried out, but the research mainly focuses on various coordination and optimization scheduling methods during the operation of cascade hydropower. [0003] Patent [1] proposes a cascade hydropower "virtual pumped-storage power station" scheduling method, with the minimum deviation between the actual and target peak-shaving power and the minimum water consumption of the cascade hydropower as the scheduling objectives, and constructs a cascade hydropower "virtual pumped-storage power station" scheduling The objective function is used to solve the optimal dispatching in order to realize the short-term dispatching plan of the power system; [0004] Patent [2] ...
