Among the core equipment of the energy storage power station, in addition to the battery itself, there is also a key component - PCS (converter) .Let's start with an analogy: if the energy storage system is likened to an energy bank , the PCS plays a key role in storing and accessing electricity. A traditional grid-following PCS is like an obedient cashier, operating according to the voltage and frequency set by the grid. A grid-forming PCS, on the other hand, is more like a bank president (

1.Energy storage before the meter, energy storage after the meter, large energy storage, industrial and commercial energy storageThe core difference between pre-meter energy storage and post-meter energy storage lies in the deployment location and application scenario: pre-meter energy storage is directly connected to the grid side (before the meter), serving the grid peak regulation, new energy consumption, etc.; post-meter energy storage is deployed on the user side (behind the meter), mainly

Probabilistic Design Methods for Wind Turbines, has been officially released.Recently, the International Electrotechnical Commission's Technical Committee on Wind Energy Generation Systems (IEC/TC 88) officially released IEC TS 61400-9: 2025, Wind energy generation systems-Part 9: Probabilistic design measures for wind turbines.Currently, the industry generally adopts a deterministic design approach when designing wind turbines. This approach ensures design safety by introducing a safety fac

1. IntroductionIntegrated solar-storage systems, also known as PV + Storage, combine photovoltaic (PV) solar panels with energy storage solutions (typically lithium-ion batteries) to maximize renewable energy utilization. These systems enhance energy independence, reduce grid reliance, and improve efficiency by storing excess solar power for later use.2. Key Components(1) Solar PV ArrayConverts sunlight into DC electricity.Common types: Monocrystalline, Polycrystalline, Thin-film.(2) Hybrid Inve

With the rapid development of clean energy sources like wind and photovoltaics, the power system faces a core challenge: the inability to perfectly align electricity production and consumption across time and space . Energy storage power stations, the energy warehouses that address this challenge, store electricity and release it when needed, effectively balancing power supply and demand and stabilizing grid operations.three main types based on their connection location and primary function : po

1）Why Fire Suppression is Essential in BESSBattery Energy Storage Systems (BESS) are critical for storing clean energy from solar and wind power. But these high-energy systems carry a real fire risk, especially with lithium-ion batteries.Once a battery starts overheating or goes into thermal runaway, it can cause explosions, toxic gas leaks, and system failure.This is why fire suppression systems in BESS are not optional—they’re essential for safety, compliance, and peace of mind.2）Fires in

The first role: Integrator - the general assembler of energy storage equipmentenergy storage cabinet door, and the most striking thing inside is the rows of battery packs, which take up 70% of the cabinet's volume . But batteries alone aren't enough; they also require an inverter (to convert the battery's DC power into AC power for the factory), a fire protection system (such as a gas fire extinguisher), a temperature control system (to prevent thermal runaway in the summer, air cond

The Power Conversion System (PCS) is the core energy conversion device in the energy storage system that connects the energy storage battery with the external power grid or load. It can be called the energy center of the entire system. Its core function is to achieve bidirectional conversion between direct current (DC) and alternating current (AC), and it also undertakes key tasks such as energy scheduling and safety control of the energy storage system.At the energy conversion level, the core v

Introduction to Photovoltaic (PV) Energy StoragePhotovoltaic energy storage systems (PV ESS) combine solar power generation with battery storage to maximize energy efficiency, ensure power reliability, and enable energy independence. These systems capture solar energy during the day, store excess electricity in batteries, and discharge it when needed—such as during nighttime, peak demand periods, or grid outages.1. Core Components of a PV Energy Storage SystemA typical PV energy storage system

1. What is a photovoltaic energy storage system?1. 1 Definition of photovoltaic energy storagePhotovoltaic energy storage system, also known as solar photovoltaic energy storage system, is an important energy utilization method that combines solar photovoltaic power generation with energy storage technology. The system converts solar energy into electrical energy through photovoltaic panels and uses energy storage devices (such as battery packs) to store this electrical energy so that it can sup
