In-depth discussion of energy storage battery technology, battery energy storage value evaluation research and battery energy storage device applications, etc.
China’s microgrid technology research is still in its infancy, but some microgrid pilot projects have been completed and put into operation. including: Henan Zhengzhou Caizhuan Optical Storage Microgrid Pilot Project. This is a microgrid pilot project in the State Grid Corporation’s smart grid pilot project, relying on the roof photovoltaic power generation project of Henan […]
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 development of Japan’s micro grid is based on the problems of China’s increasing energy shortage and load growth. The Japanese government very much hopes that renewable energy can play an important role in Japan’s energy structure. Therefore, micro grid research and pilot are positioned to solve the diversification of energy supply, reduce pollution and […]
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 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 […]
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 […]
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 […]
Reduce the cost of distribution transformer loss The loss of the transformer mainly includes no-load loss and short-circuit loss (load loss). No-load loss, also known as iron loss, is the loss generated when the magnetic flux changes periodically due to the excitation current in the iron core under the rated voltage of the transformer, so […]
