Abstract

The invention discloses an energy router and a power generation control method based on the energy router. When a plurality of ports cooperatively work, system stability is guaranteed and a work mode is reasonably designed. The invention provides a seven-interface direct current bus energy router model. The model comprises wind energy, photovoltaic power generation, energy storage and alternating current and direct current loads, a power grid and other energy router interfaces. Aiming at the above configuration, an integral control strategy of the energy router is designed. Two working modes of on-demand power generation and maximum power generation are included and energy can be reasonably transmitted.

Description

technical field [0001] The invention relates to the technical field of micro-grids, in particular to an energy router and a power generation control method based on the energy router. Background technique [0002] With the development of distributed energy, micro-grid and other technologies, a large number of energy supply or energy-consuming devices need to be connected to the energy transmission network, and the traditional transmission network cannot meet the needs of extensive access to various energy sources. Energy routers can realize the interconnection, scheduling and control of various energy networks. However, new energy power generation such as photovoltaics and wind power are greatly affected by the environment, and it is difficult to precisely control the power generation, and the control constraints are more stringent; the system composed of multiple power sources is more difficult to analyze and the control strategy is more complicated; multiple ports There a...
