Abstract

The invention discloses an off-grid wind / hydrogen hybrid renewable energy system optimization method based on an empire competition algorithm, and belongs to the technical field of off-grid wind / hydrogen hybrid renewable energy system capacity optimization, and the method comprises the steps: building an optimization model, and optimizing the total net annual cost; the empire is initialized; in combination with optimal mixing of each component of the off-grid wind-hydrogen hybrid renewable energy system, the standardization power of each imperialist country is defined; the colonies to which the empire belongs continuously approach the empire; judging whether the colony cost in the empire range is lower than that of the empire or not; calculating all total costs of the empire; imperialist competition; eliminating the weakest empire, and stopping the algorithm when only one empire is left in a circulation result; the optimal total net annual cost is further obtained; according to the method, the specific cost of each part of the off-grid wind-hydrogen hybrid renewable energy system can be effectively mastered, the calculation method is fast in convergence, the annual net total cost of the system and the probability of power supply loss are effectively and accurately reduced to the minimum, and the economic benefit is huge.

Description

technical field [0001] The invention belongs to the technical field of capacity optimization of an off-grid wind / hydrogen hybrid renewable energy system, and in particular relates to an optimization method for an off-grid wind-hydrogen hybrid renewable energy system based on an imperial competition algorithm. Background technique [0002] Wind energy is widely recognized as attractive to remote regions and is expected to form a significant part of the mix by 2050. On the other hand, hydrogen, a new environmentally friendly energy carrier, has been tested and considered as a promising wind energy storage medium for improved reliability. As an off-grid energy solution, wind-hydrogen hybrid solutions have a huge impact on energy markets, especially in remote areas. [0003] In hybrid renewable energy systems, the optimal size of each component and the power management of the system are key issues to obtain a reliable and cost-effective hybrid renewable energy scheme. Various ...
