Design of Off-Grid Wind-Solar Complementary Power Generation System for Alpine Weather Station

Wind power generation and photovoltaic power generation are one of the most mature ways in respect of the wind and solar energy development and utilization, wind and solar complementary power generation can effectively use space and time. The two forms of power generation can play their respective advantages, replenish each other, and improve the comprehensive utilization of energy through coordination and cooperation, so as to effectively solve the power supply problem of remote areas. This paper describes the design of an off-grid wind-solar complementary power generation system of a 1500m high mountain weather station in Yunhe County, Lishui City. By analyzing the meteorological data and electricity usage of the station, the power of the two independent power generation systems, the number of photovoltaic modules, and the capacity of batteries and inverters are calculated, and a reasonable photovoltaic array is designed and the complementary control module is configured. The system can meet the electricity demand of weather station to the greatest extent, and the output power is stable, the power quality is good, and the structure is reasonable.
