User side energy storage
User side energy storage refers to the installation of energy storage batteries on the user side, which store electricity during low electricity prices or when using new energy sources such as photovoltaics and wind power. During peak electricity prices or power outages, the stored energy is used, and the user side energy storage does not participate in grid regulation. The stored energy is only supplied to the user.
The user side energy storage and power generation system combined with photovoltaics is divided into off grid power generation system and parallel off grid energy storage system. The off grid power generation system is a mandatory requirement and is suitable for areas without or without electricity; Parallel off grid photovoltaic power generation systems are widely used in frequent power outages, or in projects where photovoltaic self use cannot be fully connected to the grid and requires the installation of anti backflow measures. The self use electricity price is much higher than the grid electricity price, and the peak electricity price is much higher than the flat electricity price.
There are multiple profit models for user side energy storage, and the power factors of energy storage inverters and photovoltaic inverters are controllable and adjustable, improving the power grid environment in the factory and avoiding fines due to excessive power factors. Higher power factors can also reduce the power consumption of lines and equipment in the factory; The charging and discharging of energy storage batteries can be adjusted and controlled, utilizing the price difference between peak and valley electricity bills. Energy is stored from the grid during low electricity consumption periods at night and released from batteries during high electricity consumption periods during the day, helping enterprises manage peak electricity consumption and reducing electricity bills during peak time of use electricity prices in factories. Enterprises with conditions can also save capacity costs; Emergency backup power supply: In the event of a power outage in the power grid, a microgrid energy storage system is formed using various power generation methods such as solar energy, wind power, oil turbines, and energy storage batteries to provide uninterrupted power supply for critical loads.
