Description

technical field [0001] The present invention relates to the technical field of generating power measurement and calculation, and more specifically relates to a micro-grid wind power and photovoltaic power generation power measurement system and a micro-grid wind power and photovoltaic power generation power measurement method. Background technique [0002] With the continuous deepening of our country's environmental governance, the problem of thermal power generation for environmental pollution has also attracted more and more attention. In order to meet the development needs of the general environment, non-polluting power generation such as wind power and photovoltaic power generation has gradually emerged. [0003] Wind energy is the kinetic energy generated by the movement of large volumes of air over the Earth's surface. Wind energy resources are greatly affected by terrain, and most of the world's wind energy resources are concentrated in the coastal and open continent...

Problems solved by technology

[0006] However, in my country's wind power and photovoltaic power generation, there is such a problem, that is, traditional equipment (photovoltaic and wind power) can only realize power supply, and cannot perform instantaneous power calculation, which limits its use to a certain extent.
