Energy storage and energy release of Energy Storage Substation

With the continuous growth of global energy demand and the rapid development of renewable energy, Energy Storage Substation, as a key component of the energy system, are playing an increasingly important role. Energy storage substations can store excess power and release it when needed to balance the supply and demand of the power system, improve energy efficiency, reduce carbon emissions, and enhance the stability of the power grid.

1. Energy storage stage:

In the energy storage stage, energy storage substations use various technologies to convert excess electrical energy into energy storage form and store it for emergency needs. This phase includes the following key steps:

Energy Harvesting: When power supply exceeds demand, energy storage substations begin collecting excess power. This can be achieved in a number of ways, such as by harnessing excess electricity from wind or solar power, or by converting electricity into other forms of energy when demand for electricity is low.

Energy storage conversion: The collected excess electrical energy is converted into energy storage form and stored in the corresponding energy storage medium. Common energy storage media include battery packs, compressed air energy storage devices, water pump energy storage systems, etc. Battery energy storage typically uses technologies such as lithium-ion batteries, while compressed air energy storage uses compressed air to store it in gas tanks, and water pump energy storage raises water high to store energy.

Energy management: In the energy storage stage, energy storage substations need to manage and optimize the stored energy. This includes monitoring the storage status of energy in the energy storage medium, and adjusting and controlling the energy storage system according to the needs of the power system to ensure that energy can be safely and stably stored and supplied when needed.

2. Energy release stage:

In the energy release stage, the energy storage substation releases the stored energy according to the demand of the power system to meet the needs of the power system. The specific process of this stage is as follows:

Energy conversion: Energy storage substations convert stored energy from the energy storage medium into electrical energy or other forms of energy for transmission to the grid.

Electric energy output: The converted energy is exported to the power grid to balance the supply and demand relationship of the power system and cope with load fluctuations or emergencies.

System adjustment: During the energy release process, the energy storage substation needs to be adjusted according to the real-time conditions of the power grid to ensure that the released energy can effectively meet the needs of the power system while maintaining stable operation of the power grid.

Energy Storage Substation
An energy storage box substation is a substation that integrates a traditional substation and energy storage system in a box. It is mainly composed of transformers, circuit breakers, cable connectors, isolation switches, current transformers, voltage transformers, capacitors, reactors, energy storage devices, and other auxiliary equipment.
