Performance of Hybrid Wind-Solar Systems Under Different Weather Conditions and Power Usage Planning

The core advantage of a hybrid wind-solar system lies in its ability to adapt to various weather changes, maintaining relatively stable power output through a complementary mechanism. Understanding its performance under different typical weather conditions and flexibly arranging household electricity consumption accordingly is key to maximizing self-generated power and ensuring continuous power supply. Its operating mode can be summarized as "complementary, intelligent allocation, and user collaboration."

Performance under typical weather conditions:

Sunny and windy weather (optimal working condition): This is the system's "golden hour." Solar and wind power generation are both highly efficient, reaching peak total power output. At this time, the system can easily meet the family's immediate electricity needs throughout the day and store a large amount of surplus electricity in the battery, providing ample reserves for later use.

Sunny and windless weather: In this case, solar power "takes the lead." Power generation is sufficient during the day, but zero at night. The system behaves similarly to a pure photovoltaic system, with ample electricity during the day, but relying entirely on the battery's daytime storage for power at night. The remaining battery power is crucial.

Cloudy/rainy and windy weather: In this weather, the system's value is highlighted. Although solar power generation decreases significantly or even drops to zero due to weak sunlight, wind power generation is often strong, becoming the main power source. This "when one source is weak, the other is strong" model ensures that the system still has considerable power output, avoiding complete power outages.

Continuous cloudy and windless weather (most severe test): This is the biggest challenge the system faces. Both solar and wind power generation may be minimal. At this time, household electricity consumption will depend entirely on the electricity previously stored in the battery. The system's endurance depends on the battery capacity and previous charging status.

Intelligent power usage planning strategy based on the above performance:

To work in conjunction with the system and achieve the best power usage experience, you can develop the following habits:

Use more electricity during peak generation periods: During the day when there is good sunlight or strong winds, actively schedule high-energy-consuming and adjustable activities such as using washing machines, dishwashers, electric water heaters, and charging electric vehicles. This is called "using power as it's generated," which is the most efficient and reduces charging and discharging losses of the battery. Use electricity sparingly during periods of low power generation: During nighttime and periods of continuous inclement weather, consciously conserve electricity. Prioritize essential loads such as lighting, refrigerators, and routers, and suspend or reduce the use of non-essential high-power appliances to extend the battery's power supply time.

Utilize smart control devices: If possible, install timers on devices such as water heaters and chargers, setting them to operate automatically during the day. More advanced systems can be integrated with smart home systems to automatically activate specific appliances when power generation is abundant.

Monitor energy storage status and prepare contingency plans: Develop the habit of checking the remaining battery power daily. When continuous inclement weather is forecast and the battery level is low, switch to power-saving mode in advance or start a backup generator (if available) to "recharge" the battery.

In summary, the wind-solar hybrid system, through its "dual-engine" design, smooths out fluctuations caused by single weather conditions. By flexibly managing electricity consumption based on weather conditions and power availability, users can actively cooperate with the system's power generation rhythm, achieving stable and economical energy self-sufficiency under most weather conditions, and confidently handling extreme situations without wind or sunlight, truly realizing the synergistic value of the system where "1+1>2".
