Abstract

The invention discloses a smart energy management device of a multi-energy power supply system. The smart energy management device of the multi-energy power supply system comprises a photovoltaic power generation device, a wind power generation device, a diesel generator device, an energy storing device, an alternating load, a direct current bus device, an alternating current bus device, a smart controller device, a rectifier, a detection device and an inverter device. The multi-energy power supply system integrates solar energy, wind energy, a diesel generator and a storage battery device, has strong nonlinearity, and has a certain degree of inertia. According to the smart energy management device of the multi-energy power supply system, fuzzy control algorithm is used for integrated management of energy. The smart energy management device is characterized by intelligent control, effectively solves the nonlinear problem of the system, enables overshoot of the system to be reduced, even enables overshoot not to occur, and enables the system to have strong robustness and adaptivity.

Description

Technical field [0001] The invention relates to an energy intelligent management device for a multi-energy power supply system. Background technique [0002] In China's energy consumption, coal is the main energy structure. In primary energy consumption, coal resources account for 70%, while the corresponding world average is only 30%. This has made China the world's largest carbon emitter. In 2009, at the Copenhagen Summit, China promised that by 2020, China’s carbon dioxide emissions per unit of GDP will be reduced by 45% from the 2005 level. From a global perspective, the proven oil reserves can be used by 2030, natural gas by 2040, and coal can be used for about two to three hundred years. Even with modern nuclear energy, the raw material uranium reserves are very limited, and nuclear energy The danger is great. Therefore, renewable energy and energy saving and emission reduction are strategic requirements for future energy development. [0003] Currently, among renewable en...
