GW-scale energy storage power stations have significant development potential. Currently, there are plans to establish GW-scale power stations in China.
1) GW-scale energy storage power stations can coordinate control with renewable energy power stations by receiving dispatch signals from higher-le...
The principle for selecting the voltage of PV module strings is not simply to pursue the highest possible voltage. The key is to achieve a precise match with the rated input parameters of the inverter, while comprehensively considering system safety, power generation efficiency, and overal...
The three-layer architecture of a BMS system consists of the Battery Module Management Unit (BMU), the Battery Cluster Management Unit (BCMU), and the Battery Stack Management Unit (BAMS). The Battery Stack Management Unit is also referred to as the PCS (Battery Unit Management System).

Effective thermal management is critical for battery safety, performance, and lifespan. While both air cooling and liquid cooling aim to regulate temperature, they differ significantly in design, efficiency, and suitability.
How They Work
Air cooling moves air across battery surfaces u...
I. Definitions of STS and ATS
1. Static Transfer Switch (STS) is a power switching device based on electronic circuits, mainly used to achieve fast and seamless switching between two independent AC power sources. Its core components include an intelligent control board, high-speed thyristors, and ci...

I. Different Core Positioning
The core task of a PV inverter is "DC to AC conversion". The electricity generated by PV panels is DC, which cannot be directly connected to household circuits or the power grid. The inverter acts like a "converter", precisely converting the DC power into AC power...
When understanding and designing energy storage projects, two crucial yet often confusing concepts always come up: MW and MWh. Many people are puzzled about the difference between them—what exactly do they represent? Why are energy storage power plants always described using the...
With the continuous growth of global demand for clean energy, residential solar power stations are playing an increasingly important role in household energy supply. However, traditional residential solar power stations have a significant drawback: intermittent and unstable power generation. So...
The fundamental difference between grid-following and grid-forming systems lies in their reliance on and contribution to the power grid, analogous to "followers" and "co-builders" of the grid.
Grid-following energy storage systems function essentially as "current sources," depending...
Grid-following energy storage systems operate as a current source, their operation dependent on the grid's voltage and frequency. In grid-following mode, the system's converter follows the grid's phase information, measuring the phase information at the grid connection...
At the heart of every energy storage system is the Power Conversion System (PCS)—the intelligent component that manages energy flow between your batteries and the electrical grid. Its core function is bidirectional conversion: charging batteries from the grid (AC→DC) and dis...
