In-depth discussion of energy storage battery technology, battery energy storage value evaluation research and battery energy storage device applications, etc.
Since the 1990s, the United States has experienced several major power outages, which has made the power industry pay great attention to power quality and power supply reliability. Therefore, the research focus of the microgrid in the United States mainly focuses on meeting various power quality requirements, improving the reliability of power supply, reducing costs […]
The proposal of microgrid technology is closely related to the application and development of distributed generation (DG) technology. The concept of DG was first announced and officially promoted in the U.S. Public Utilities Management Policy Act of 1978, which is defined as: 1) A new power supply system that is completely different from the traditional […]
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. […]
Electricity price policies for wind power in different countries At present, the electricity price policies for wind power in various countries in the world can be divided into three categories: 1. Fixed electricity price policy; 2. Electricity price subsidy policy, especially the electricity price subsidy policy with upper and lower price limits, referred to as […]
After the energy storage link is introduced into the system, it can not only improve the reliability of system operation and the quality of power supply, but also promote the application of renewable energy. It can also more effectively utilize power equipment by smoothing the load, reduce line losses, and improve the economy of grid […]
The battery energy storage system can be set with a variety of operating modes according to different applications and user needs. The control system should determine the direction and magnitude of the power transmission of the power conversion subsystem (PCS) according to the preset operating mode, as well as the conditions of the battery and […]
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 […]
