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 […]
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 […]
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 […]
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 […]
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 […]
In urban power grids, the daily maximum load of the summer peak power consumption generally occurs around noon, but the curve between the noon peak and the light peak is flattening day by day, and the daily maximum load in some residential areas has appeared during the night light peak period. The continuous increase of […]
①Change the energy structure, reduce system fuel consumption and save energyThe power industry is currently developing rapidly. The main problem in the operation of the power system is the power supply contradiction caused by the unreasonable power supply structure, especially in some power grids dominated by thermal power, due to the lack of peaking balance […]
