The invention discloses a multi-energy ship intelligent power distribution method based on load prediction. The method comprises the steps: collecting electric power parameters; determining the actualoutput power of each energy source; acquiring a load power actual value; determining a load power prediction value; determining load power to be distributed; decomposing the load power to be distributed, and correspondingly distributing the decomposed power signal to the corresponding energy storage element to serve as a load power distribution value of the energy storage element; according to the adopted multi-energy start-stop control strategy, adjusting the output power of each energy source, and controlling the charge-discharge state of the energy storage element and the start-stop of thegenerator. According to the method, the authenticity of load prediction is enhanced, wavelet decomposition is utilized to decompose high and low frequency signals to energy storage elements with different performances, the power supply stability of a ship power grid is enhanced, the service life of the energy storage elements is prolonged, and the economic and environmental protection problems caused by frequent start and stop of a diesel generator of a ship are reduced.
Description
technical field [0001] The invention relates to power distribution of multi-energy ships, in particular to a method and device for intelligent power distribution of multi-energy ships based on load forecasting. Background technique [0002] In order to alleviate energy problems and environmental pollution problems, new energy ships have become an important direction for future ship development, and solar energy is a green energy with considerable potential. With the development of technology, the conversion efficiency of photovoltaic cells has gradually increased, and photovoltaic power generation has broad application prospects on ships. However, due to the intermittency of solar energy, the size, space and large navigation area of the ship, on large ocean-going ships, it is difficult to meet the load demand power of the whole ship only by relying on photovoltaic power generation, and it is also difficult to ensure the reliability of the ship's power supply. diesel gener...
