Abstract

The invention provides an operation optimization method for a hybrid microgrid system with a hydrogen fuel cell, comprising: obtaining operating cost parameters and production emission parameters of the hybrid microgrid system; establishing an operating cost model according to the operating cost parameters, and establishing a production emission according to the production emission parameters model; use the particle swarm optimization algorithm to solve the operating cost model and the production emission model respectively, and obtain the optimization results according to the solution results. The present invention carries out corresponding modeling based on the operation cost and production emission cost of the hybrid microgrid, and finds out the optimal solution of the operation cost and production emission cost, so that the optimization result can accurately command and dispatch the operation of the hybrid microgrid, and reduce the operation cost And while ensuring the smooth operation of the main grid, it can effectively reduce the emission of the hybrid micro grid, which is conducive to environmental protection.

Description

technical field [0001] The invention relates to the technical field of power grid operation and maintenance, in particular to a method for optimizing the operation of a hybrid micro-grid system with a hydrogen fuel cell. Background technique [0002] A hybrid microgrid refers to a grid composed of distributed energy sources, generally composed of a turbine power generation unit, a hydrogen fuel cell unit, a solar cell unit and a battery storage unit, to inject power into the main grid when the power of the main grid is insufficient. [0003] However, during the operation of the hybrid microgrid, more greenhouse gases such as nitrogen oxides, carbon dioxide, and sulfur dioxide are often produced due to the lack of reasonable optimal operation, which has an impact on the environment, and more much cost. Contents of the invention [0004] In view of this, an embodiment of the present invention provides an operation optimization method for a hybrid microgrid system with a hyd...
