Multi-objective power configuration optimization method for multi-energy ship microgrid

Abstract

The invention relates to a multi-objective power configuration optimization method for a multi-energy ship microgrid, which is characterized in that in allusion to a ship microgrid system containing diesel generators, wind power generation, photovoltaic power generation and battery energy storage, a critical output point of an energy storage system under a dynamic load is studied, the critical output point is enabled to act as judgment for performing preferential output by diesel storage, and an energy storage system scheduling strategy for preferentially selecting diesel storage based on the dynamic critical point is built. The method can realize power supply configuration optimization for a dynamic multi-objective microgrid in a real sense.

Description

technical field [0001] The invention relates to the field of multi-energy ship energy planning, in particular to a multi-objective power supply configuration optimization method for a multi-energy ship microgrid. Background technique [0002] In modern society, transportation is the basic need and prerequisite for economic development, and water transportation, as the second largest energy consumption transportation mode, has the characteristics of large transportation volume and low cost. As the transportation industry incorporates the goal of reducing greenhouse gas emissions, a green, environmentally friendly and low-carbon shipbuilding model will become an inevitable direction for the future development of the shipbuilding industry. In the context of the country's accelerated promotion of "Made in China 2025", the application of new energy on ships has received extensive attention, and how to effectively and rationally use clean energy such as wind energy, solar energy, ...

Problems solved by technology

[0003] The existing technology is to optimize the power supply type and capacity parameters of the microgrid under a specific static control strategy, that is, in the entire dispatching process, the diesel generator is fixedly used to meet the system requirements, and the energy storage system is only used as a supplementary energy source, or fixedly used The energy storage system is used to meet the requirements of the system, and the diesel generator is only used as a supplementary energy source, without fully considering the characteristics of the battery energy storage system that dynamically absorbs or releases energy, and the uncertainty of the composition ratio of energy sources in the battery energy storage system, resulting in Therefore, from the perspective of economics, according to the real-time energy source ratio of the energy storage system, which one should be used as a supplement for the diesel generator or the energy storage system? Energy should be a dynamic situation
