混合独立发电系统功率协调策略与仿真

Power Coordination Strategies for Hybrid Isolated Microgrid and Its Simulation

传统的煤炭、石油等一次能源是不可再生的,终归要走向枯竭。因此加强可再生能源的利用,成为解决我国能源需求增长与能源紧缺、能源利用与环境保护之间矛盾的必然选择。以可再生能源的综合利用为指导思想,建立了包含风机、燃料电池、燃气轮机和电解槽的微网系统,分析了系统在整个运行过程中能量产生、转换、储备和消费各个环节的工作方式,提出了切实可行的功率协调策略,并用Simulink仿真验证了该微网系统的可行性。该供电方式可在解决边远地区的能源供应问题中发挥积极的作用。

It becomes an inevitable choice for China to enhance the utilization of renewable energy resources to solve the contradiction between the demand growth of energy resources and energy pinch and that between energy utilization and environmental protection due to the eventual depletion of traditional nonrenewable primary energy resources such as coal and petroleum. Under the guiding ideology on comprehensive utilization of renewable energy resources, a microgrid containing wind turbines, fuel cells with proton exchange membrane, micro gas turbines to supply base load and electrolyzer system to manufacture hydrogen is built, and the operation modes of different links such as the production, transformation, reservation and consumption of energy in the whole operation process of the microgrid are analyzed, and a practicable power coordination strategy is proposed. By means of the simulation by Simulink, the feasible of the built microgrid is verified.
