Stochastic measurement of wind power using a two-bit A/D converter

•We propose a new method for stochastic measurement of wind power and energy.•The experimental results show that wind power and energy can be measured with an accuracy of 0.09%.•The proposed method can be easily implemented in hardware.•The proposed method can be easily integrated with cup anemometers. This paper presents a new method for stochastic measurement of wind power and energy. Compared to the existing approaches, this method has two advantages: first, it is much simpler and cheaper to implement, and second, it can be easily integrated with cup anemometers. In this way, it is possible to construct a low-cost mobile device capable of measuring wind power and energy. In order to prove the validity of our method, we have conducted several laboratory experiments. The obtained results have shown that, over the time interval of 100 s, wind power and energy can be measured with an accuracy of 0.09%.
