  According to CCTV News, on January 7, the largest tidal flat photovoltaic storage power station in the country and the largest single-unit photovoltaic project in operation in Shandong Province, the Huadian Shandong Laizhou Large-scale Salt-alkali Tidal Flat Photovoltaic Storage Integrated Project, was connected to the grid for power generation. The entire project covers an area of ​​18,000 mu, with a total of nearly 2 million photovoltaic panels laid. After all are put into production, it will not only provide a steady stream of clean electricity, but also inject brine under the photovoltaic panels to increase salt production and income for local people. The Huadian Laizhou Large-scale Salt-alkali Tidal Flat Photovoltaic Storage Integrated Project is one of the third batch of large-scale wind power photovoltaic bases in the country, with an installed capacity of 1,000 megawatts and supporting construction of a 200 megawatt/400 megawatt-hour electrochemical energy storage project. The power station integrates "photovoltaic power generation + salt production" and realizes a composite industrial model. It is reported that after the project is put into production, it can generate 1.442 billion kilowatt-hours of electricity per year, which can meet the annual electricity consumption of about 500,000 households. 444,000 tons of standard coal are saved annually. The salt-light complementary mode is adopted. The solar panels all use double-sided double-glass technology. Under the irradiation of sunlight, the brine reflects light to the back of the module, which can increase the power generation efficiency by about 3%. At the same time, the photovoltaic modules have a thermal effect, which can increase the temperature of the salt pool by about 2°C, increase the concentration of brine, and increase the salt production, thus achieving a complementary and win-win situation between salt production and photovoltaic power generation. The project also built a supporting energy storage system power station. The white boxes in the picture above are like huge power banks. When the sun is strong during the day, the excess solar energy is stored here, and the stored electricity is released at night, becoming a photovoltaic power station that can generate electricity at night. At the same time, due to the use of new electrochemical energy storage technology, it not only has the function of a power bank, but also can play a role in voltage stabilization and frequency regulation when the power grid fluctuates, ensuring the safety and stability of the power grid. Tidal flat photovoltaic energy storage power stations usually refer to photovoltaic energy storage projects built in complex areas such as sandy and silty areas along the coast of oceans and rivers with excellent sunshine conditions. Taking the Huadian Laizhou saline-alkali tidal flat photovoltaic storage integrated project as an example, the annual average sunshine time here is more than 2,600 hours...

  It is reported that on December 25, the largest electrochemical energy storage project in China, the Longdong to Shandong UHV DC transmission project supporting new energy energy storage system project, officially started construction in Huanxian County, Qingyang City.   The Longdong to Shandong UHV DC transmission project is one of the major projects determined to be implemented in the National "14th Five-Year Plan" Outline and the Yellow River Basin Ecological Protection and High-quality Development Plan. It is also my country's first UHV project for "wind, solar, thermal and storage integration" power transmission. Among them, the new energy supporting energy storage project of Huaneng Longdong Energy Base is configured according to 10% of the installed capacity of new energy and a 4-hour scale, with a total capacity of 600 MW/2400 MWh. It is divided into two sites for construction, and a 300 MW/1200 MWh electrochemical energy storage power station is built at each site.   It is understood that the energy storage power station adopts the single-stage distributed energy storage technology independently developed by Huaneng. It is composed of hundreds of battery cells connected in series to form a battery cluster. Each battery cluster is distributed through a single low-power PCS for energy processing. The battery is only connected in series and not in parallel, and the battery cluster is independently controlled. Multiple PCS modules are connected in parallel on the AC side. This technology is more compatible with batteries and can achieve one cluster one management; each distributed converter series battery cluster is smaller in scale, more integrated, and more refined, eliminating the impact of centralized parallel circulation and capacity loss, and the operation and maintenance are simple and flexible. It has advantages in the consistency of battery cluster working state, system capacity availability, cycle life, and system availability under faults. The average comprehensive efficiency is about 4.6 percentage points higher than that of centralized technical route power stations, and the average available capacity retention rate is about 5 percentage points higher.   The project is planned to be completed and put into operation simultaneously with the Longdong to Shandong UHV DC transmission project in the first half of 2025. After completion, it will consume about 840 million kWh of new energy electricity annually, and can store about 2.4 million kWh of electricity per charge, which can meet the daily electricity demand of 480,000 households at most.   The "wind, solar, thermal, storage and transmission" integrated development model of the Longdong to Shandong UHV DC transmission project plays an important role in effectively solving the problems of new energy consumption, improving the flexibility of the power system, and improving the safe and stable operation of the power grid. At the same time, it helps to acc...
