Integrated Wind-Solar Hybrid System Solution: Coordinated Configuration of Power Generation Units and Energy Storage Systems

The core advantage of a wind-solar hybrid system lies in utilizing the natural complementarity of solar and wind energy over time—typically, there is good sunlight and relatively little wind during the day, while strong winds are possible at night when there is no sunlight, thus creating a more continuous and stable power output. When designing the system, it is crucial to objectively assess the solar and wind energy resources at the installation site, avoiding a simplistic "one-size-fits-all" configuration. The ideal ratio is: in sunny, low-wind areas, solar power should be the primary source, supplemented by wind power; in cloudy, monsoon-prone areas, or areas with high nighttime electricity demand, the proportion of wind power generation can be appropriately increased. The capacities of the two power generation units need to be designed collaboratively to create a smoother overall power generation curve, reducing the instantaneous pressure on the energy storage system.

The energy storage system is the key "regulatory pool" coordinating wind and solar power generation with electricity demand. Its capacity configuration mainly depends on two factors: first, the "longest expected period" of continuous windless and solar-less conditions in the local area, which determines how much electricity needs to be stored to weather the storm; and second, the typical daily electricity consumption of a household or load. A practical principle is that energy storage capacity should be able to meet the needs of critical loads for a period of time (e.g., 1-3 days) without wind and solar supplementation. Simultaneously, the performance of the controller is crucial; it must intelligently manage the energy flow between photovoltaic panels, wind turbines, batteries, and loads, prioritizing the use of readily generated green electricity and providing scientific charging and discharging protection for the batteries.

Successful integration of the entire system depends on accurate load analysis and professional equipment selection. Detailed statistics on the power consumption and usage time of all household appliances are needed to distinguish between critical loads that must be guaranteed (such as lighting and refrigerators) and adjustable loads (such as water heaters), thereby determining the total power and energy requirements of the system. Finally, selecting technologically mature and performance-matched photovoltaic modules, wind turbines, integrated controller inverters, and battery brands ensures that all components work efficiently and collaboratively to achieve optimal safe, reliable, and economical operation.
