How to achieve 24-hour uninterrupted power supply on farms: Configuration guide for wind and solar hybrid systems

In order to achieve uninterrupted power supply for farms around the clock, relying solely on the power grid or a single energy source is risky. Building a set of wind and solar complementary microgrids with wind and solar power as the main power, energy storage system as the core, and backup power supply as the guarantee is currently the most reliable and economical off-grid or enhanced power supply solution.

The core of system configuration is the balance of power generation, energy storage and management.

Power generation unit combination: According to the resource characteristics of the area where the farm is located, the capacity ratio of solar photovoltaic panels and wind turbines should be reasonably configured. Areas with good sunlight are dominated by photovoltaics, and areas with abundant wind energy increase the proportion of wind turbines. The two are naturally complementary in time and season, and can significantly smooth the power output curve.

Energy storage system - the "power bank" of the system: This is the key to achieving 24-hour power supply. An energy storage battery pack (such as a lithium battery) with sufficient capacity must be configured, and its capacity must be able to store all the key load electricity on the farm for at least 2-3 windless, rainy days. The battery is charged when wind and solar power generation is sufficient and discharged when power generation is insufficient or at night.

Intelligent management and backup guarantee: An intelligent energy management system is needed to automatically coordinate power generation, energy storage and electricity consumption. When it is predicted that the scenery will be insufficient for a long period of time, the system should be able to automatically start the backup diesel generator and charge the battery to ensure that power is not interrupted. The system also needs to be able to prioritize critical loads (such as refrigeration, lighting, water pumps).

Implementation step guide:

Step 1: Accurately calculate electricity demand: List all equipment that needs power, calculate its power and daily running time, distinguish between critical loads and adjustable loads, and obtain the total daily power consumption.

Step 2: Assess local wind and solar resources: Obtain local annual sunshine and wind speed data, or conduct short-term actual measurements as a basis for designing power generation capacity.

Step 3: System capacity design: Based on power demand and resource data, work with professionals to determine the capacity and model of photovoltaic, wind power, energy storage batteries and backup generators.

Step 4: Professional installation and commissioning: Ensure that all equipment, especially energy storage systems and electrical connections, are installed and commissioned by a professional team, and clear operation and maintenance procedures are formulated.

Through the scientific configuration of wind and solar hybrid systems, farms can establish a highly independent and resilient energy supply system that can not only effectively cope with the risk of power outages, but also reduce long-term operating costs through the use of clean energy, achieving dual benefits of production and environmental protection.
