Introduction to the background of energy storage power station construction

When was the first electricity storage system invented?

The first electrical energy storage systems appeared in the second half of the 19th Century with the realization of the first pumped-storage hydroelectric plants in Europe and the United States. Storing water was the first way to store potential energy that can then be converted into electricity.

What is pumped storage power station (PSPS)?

The pumped storage power station (PSPS) is a special power source that has flexible operation modes and multiple functions. With the rapid economic development in China, the energy demand and the peak-valley load difference of the power grid are continuing to increase.

What are battery storage power stations?

Battery storage power stations are usually composed of batteries, power conversion systems (inverters), control systems and monitoring equipment. There are a variety of battery types used, including lithium-ion, lead-acid, flow cell batteries, and others, depending on factors such as energy density, cycle life, and cost.

Why do battery storage power stations need a data collection system?

Battery storage power stations require complete functions to ensure efficient operation and management. First, they need strong data collection capabilities to collect important information such as voltage, current, temperature, SOC, etc.

Why is large-scale electricity storage important?

Naturally, large-scale electricity storage technology can reduce the many intrinsic failures and weaknesses of the grid system, help improve grid efficacy, fully integrate intermittent renewable resources, and efficiently manage energy production. Electric energy storage provides two more critical advantages.

Do energy storage technologies meet all large-scale grid performance demands?

The research and demonstration of energy storage have been extended by the rapid growth of energy storage technologies from small to large scale. However, energy storage demands vary extensively, driven mainly by the application type. No single technology meets all large-scale grid performance storage demands and metrics.
