The invention discloses a power optimization distribution method of a heat and power combined energy storage power station, comprising: collecting relevant parameters of the heat and power combined energy storage power station; using the relevant parameters as an index vector of the power station; The division boundary of the state, power storage power coefficient, heat storage power coefficient, etc. are used as the judgment conditions of the random forest neural network; the working state category of the power station is defined; The probability of exceeding the safe operating range in the state, the combination with the smallest probability is retained as the training sample; the training sample is used to generate and optimize the random forest neural network, and the state quantity of the energy storage system for a period of time in the future is used as the input value, and the random forest neural network outputs The working mode of the heat and power combined energy storage power station solves the demand problem of the control strategy for the power distribution of the energy storage battery and the heat storage system in the ultra-short term in the future.
Description
technical field [0001] The present application relates to the field of energy storage technology, in particular to a method for optimal distribution of power in a combined heat and power energy storage power station, and at the same time relates to a device for optimizing power distribution in a combined heat and power energy storage power station. Background technique [0002] With the rapid development of new energy power generation, especially photovoltaic and wind power generation, the proportion of its grid connection is also increasing year by year. The volatility and intermittency of photovoltaic and wind power generation also bring new problems to the power system, and energy storage is an effective solution. In order to stabilize the system fluctuations caused by large-scale photovoltaic and wind power generation, it is necessary to configure a large-capacity energy storage system. [0003] Under the circumstances that pumped water storage and compressed air energy...
