Energy management and control device and method for multi-energy ship

Abstract

The invention discloses an energy management and control device for a multi-energy ship. The device comprises an acquisition module for electric power parameters of the ship, a ship load prediction module, an energy management and distribution module and a control execution module, wherein the acquisition module for the electric power parameters of the ship acquires the electric power parameters of the multi-energy ship, and the electric power parameters are preprocessed by the ship load prediction module; a load prediction model is trained, and a load prediction data value at a current momentis calculated; the energy management and distribution module acquires ship driving control information; and a Q-learning algorithm is utilized to solve a multi-energy power distribution target in combination with the load prediction data value at the current moment; the control execution module acquires a solution; and therefore, distribution of various energies of the multi-energy ship are controlled. The invention further provides a corresponding control method. According to the characteristics and real-time operation conditions of a multi-energy power system, various energy sources are reasonably distributed and coordinately controlled, so the voltage and frequency fluctuation of the ship power grid is reduced, and the electric energy quality of a ship power grid and the economic performance of ship operation are optimal.

Description

technical field [0001] The invention relates to the field of ship energy control, in particular to a multi-energy ship energy management control device and method. Background technique [0002] Due to the increasingly high requirements for the power supply quality of ship power stations and the power quality of ship power grids, the research on them has become a hot research direction of ship power systems. At the same time, in order to alleviate energy problems and environmental pollution problems, ships with high power supply quality that incorporate new energy have become an important development direction for future ships. However, the contingency and time difference characteristics of new energy sources require their use in conjunction with energy storage components. At the same time, the energy management mode in modern equipment is usually set manually. The simplest way is to manually control the start and stop of the diesel generator set of the ship and the working ...
