In-depth discussion of energy storage battery technology, battery energy storage value evaluation research and battery energy storage device applications, etc.
Microgrid operation control and protection technology Compared with the conventional power system, the capacity of the microgrid is generally not large, and most of the connected power is the inverter power supply using power electronic devices, lacking a certain rotating reserve capacity. How to ensure the stability of the voltage and frequency of the system […]
Microgrid includes the process of generating, storing, and using electricity. This section analyzes the key technologies and technological development level of microgrid based on the characteristics of microgrid power supply types and operation modes. Microgrid optimization planning technology Microgrid optimization planning and design is a scientific microgrid energy storage composition and topology design under the […]
Compared with developed countries, China’s research on distributed generation and microgrid started relatively late. At present, electric power companies, many universities and research structures are paying attention to this field, and under the support of the national “973” and “863” programs, some research work has been carried out in this field, and some staged research […]
The access of distributed power sources has a profound impact on the power grid, which brings new challenges to the operation, control and protection of the power distribution network. Extensive and in-depth research was carried out. Among them, the three countries and regions of the United States, Europe and Japan are the most advanced in […]
Reduce the construction capacity of wind farm grid-connected channels China has a vast land area and complex terrain conditions. The status and distribution characteristics of wind energy resources vary with the terrain and geographical location. The areas rich in wind energy resources are mainly distributed in the southeast coast and nearby islands and northern areas. […]
Against the background of increasingly tense global environmental protection and resource pressures, China’s energy situation is particularly severe. As a new energy technology with great potential and mature technology, wind power has an increasing application scale. The installed capacity of wind power is 150 million kw. The adverse impact of large-scale wind farm grid connection […]
Judging from the actual application of large-capacity energy storage systems, Japan, the United States and other countries are currently the countries with the most applications of energy storage systems in the world. Tokyo Electric Power Company is in an international leading position in the research and development of sodium-sulfur battery systems, and has relatively mature […]
With the growth of electricity demand increasing year by year, the problem of low load factor (Load Factor) generally exists in the distribution network of large load centers. For example, during the day, there is a big difference in the need for electricity between day and night. Newly built power plants and transmission systems that […]
①Reduce the operating costs of power generation companies and power grid companies, and reduce users’ electricity costsThe operation and maintenance of the energy storage system is relatively simple, while the operation and maintenance of the power plant or the power grid are relatively complicated. After the energy storage system is put into operation, the operation […]
①Improve the safety and reliability of power supply of the power gridAccording to the summary of the current research results of battery energy storage system, the electric energy storage system can be applied to the following fields in the power grid:1) Voltage control: Support heavy-load feeders, provide power factor correction, reduce the restriction requirements of […]
