The difference between the two lies in their application scenarios and scale. Residential energy storage is mainly used for energy management within a single residence and is relatively small in scale; while distributed energy storage is mainly used in large power grids and can handle larger-scale energy storage and release.
Operating modes of residential energy storage systems
Household energy storage systems are a new type of hybrid system that combines batteries, hybrid inverters, and photovoltaic panels to store electricity, based on traditional grid-connected photovoltaic power generation systems.
1. Morning: Sunlight intensity is weak, energy production is low, and energy demand is high; at sunrise, the solar panels begin to generate energy, but this is still insufficient to meet the morning's energy needs; the energy storage system draws on the electricity stored in the batteries to power electrical appliances.
2. Midday: Sunlight intensity is strongest, solar panels produce the most energy, and energy demand is low. The energy generated by solar panels reaches its peak during the day. However, since no one is home, energy consumption is very low, so most of the generated energy is stored in the batteries.
3. Nighttime: Low sunlight intensity, low energy production, high energy demand. The highest daily energy consumption occurs at night when solar panels produce very little or no energy. The TGPRO energy storage system will utilize energy generated during the day to meet energy needs.
Overall, residential energy storage is aesthetically pleasing, easy to install, and equipped with long-life lithium-ion batteries. When combined with photovoltaics, it can provide electricity for residences, public facilities, small factories, and other locations.
Distributed storage involves distributing data across multiple storage servers, creating a virtual storage device from these distributed resources. In reality, the data is scattered throughout the enterprise. The advantages of distributed storage include improved system reliability, availability, and access efficiency, as well as easy scalability.
