Small wind turbines have the advantages of flexible regional distribution, less land occupation, and easy maintenance, and have been widely used in areas with power shortage or immature power supply conditions. In recent years, with the acceleration of the development of island tourism, marine aquaculture, oil and gas development and other marine activities, the demand for electricity in such offshore scenarios is also increasing, bringing opportunities for the development and utilization of small wind power. At the same time, with the continuous promotion and application, the technical performance of wind turbine generator units, electric control system equipment and wind/solar storage micro grid has been further improved and become more mature, which shows us a broad market and application scenarios.
