The invention discloses a multi-energy ship control management method and device based on a load prediction algorithm, and the method comprises the steps: collecting load data and temperature and humidity climate data, and carrying out the preprocessing of the collected data, and determining a training sample set; establishing a load prediction model by adopting a least square support vector machine algorithm; training a load prediction model based on the training sample set, performing parameter optimization through a particle swarm algorithm, and determining an optimal load prediction model; acquiring current load data, on-off state data and temperature and humidity climate data, and inputting the current load data and the temperature and humidity climate data into the optimal load prediction model to obtain a ship load prediction value; collecting ship electric power parameters, and obtaining input power; and based on the input power, the ship load predicted value and the on-off state data, controlling electric propulsion of the ship, ship energy equipment and on-off states of first-level, second-level and third-level loads. The change condition of the ship load can be grasped in time, the diesel generator is increased or closed, and the operation cost is reduced.

Description

technical field [0001] The invention relates to a multi-energy ship control and management device, in particular to a multi-energy ship control and management method and device based on a load forecasting algorithm. Background technique [0002] According to the characteristic of load variability in the ship power system, the output status of the multi-energy ship is allocated from various angles to ensure the stable and safe power supply of the ship. The training set is composed of the historical load data of the ship, and the environmental factors in the ship load forecasting are harsh. While ensuring the safe and stable power supply of the ship power system, it is necessary to take into account the economic performance of the power system operation. The existing multi-energy ship control and management devices mostly use manual methods to realize ship energy management: through simple demand analysis, when the ship needs to speed up or slow down, start or reduce the diese...
