ZDDQ is committed to the power quality industry, keeping up with the development of the field, and is now cooperating with FGI on the energy storage industry (ESS).
An energy storage system (ESS) is a technology that stores excess electrical energy and releases it when needed. It helps to enhance the reliability, stability, and efficiency of electrical power systems by addressing the intermittency and fluctuations in renewable energy sources like photovoltaic systems. Energy storage systems play a crucial role in balancing the supply and demand of electricity, especially during peak usage periods or when renewable energy generation is not sufficient.
There are various types of energy storage systems available, including:
1. Batteries: These are the most commonly used energy storage systems and can store electricity in chemical form. Examples include lithium-ion batteries, lead-acid batteries, and flow batteries.
2. Pumped Hydro Storage (PHS): PHS systems store energy by pumping water to an elevated reservoir when demand is low, and then releasing it through turbines to generate electricity when demand is high.
3. Compressed Air Energy Storage (CAES): CAES systems store energy by compressing air and storing it in underground caverns. When electricity is needed, the compressed air is released and expanded through turbines to generate electricity.
4. Flywheels: Flywheel systems store energy in the form of rotational motion. They use a spinning rotor to store kinetic energy, which can be converted back into electricity when needed.
5. Thermal Energy Storage (TES): TES systems store energy by storing and releasing heat. They can use various materials like molten salts, phase change materials, or heated water to store thermal energy for later use.
These
energy storage systems can be deployed at different scales, ranging from small-scale residential systems to large-scale utility-level installations. They help ensure a stable and reliable supply of electricity, promote grid integration of renewable energy sources, and enable load shifting to optimize energy consumption patterns.
