This category of articles introduces several typical distributed power sources and the role, types and characteristics of energy storage equipment, etc.
When designing the capacity configuration of energy storage equipment in a distributed power generation system, the main factors that need to be considered are: the self-supply power supply time of the energy storage equipment, the maximum energy storage requirements, the depth of discharge and the correction calculation of other influencing factors, etc. The following takes […]
Read MoreDistributed power sources are intermittent and fluctuating power sources, and their power generation has obvious randomness and uncertainty, and it is easy to have an impact on the operation of the power grid and even cause power accidents. In order to make full use of renewable energy and ensure the reliability of its power supply, […]
Read MoreSuperconducting magnetic energy storage technology In the 1970s, Superconducting Magnetic Energy Storage (SMES) began to be used in power systems. Superconducting magnetic energy storage uses the characteristic that the resistance of a superconductor approaches zero when the temperature is close to absolute zero to store electrical energy in the superconducting coil without loss. The core […]
Read MoreThe core component of Super Capacitor Energy Storage (SCES) is the super capacitor. It is a new type of energy storage element that has been mass-produced in recent years. Its energy density is very high, it has both the advantages of high-efficiency discharge power of electrostatic capacitors and the large charge storage capacity of batteries, […]
Read MoreBattery energy storage technology The development of batteries has a long history and is currently the most widely used energy storage technology in distributed power generation systems. The battery energy storage system (Battery Energy Storage System, BESS) is mainly composed of battery packs, inverters, controllers and other auxiliary equipment. According to the different chemical substances […]
Read MoreWith the development of new energy technologies and smart grids, energy storage equipment is of great significance in some distributed power generation systems based on clean energy (such as wind power generation, solar power generation, etc.). Due to the intermittent nature of wind power generation and solar power generation, its output electrical energy also has […]
Read MoreFeatures of fuel cell The distributed fuel cell demonstration power station uses natural gas as fuel. The natural gas is first converted into hydrogen, which is then sent to the fuel cell generator set to produce electricity and hot water. In principle, as long as the fuel cell continuously inputs reactants and discharges reaction products, […]
Read MoreA fuel cell is a power generation device that directly converts the chemical energy of fuel and oxidant into electrical energy. In 1839, British scientist W.R.Grove discovered and verified the phenomenon of fuel cells in the laboratory. However, due to the failure of the research on the dynamics of generators and electrode processes to keep […]
Read MoreAccording to the different ways of concentrating solar energy, solar thermal power generation systems can be divided into three types, namely trough solar thermal power generation systems, tower solar thermal power generation systems and dish solar thermal power generation systems. (1) Trough solar thermal power generation system. Trough solar thermal power generation system uses trough-shaped parabolic […]
Read MoreGenerally speaking, solar thermal power generation technology refers to solar steam thermal power generation technology. It uses a large-scale array of parabolic or dish-shaped mirrors to collect solar thermal energy, provides steam through a heat exchange device, and combines the technology of traditional steam turbine generators to achieve the purpose of generating electricity. It avoids […]
