Description

Multi-group multi-group regional mutual aid power generation system

The invention relates to a multi-group multi-group regional mutual-assisted power generation system, in particular to a power mutual assistance system capable of transmitting power through the AC grid and switching control technology, and can be superimposed and expanded into a multi-group according to the number of users, and the integrated area Internal natural energy power generation, an environmentally friendly power system that effectively reduces the consumption of the earth's resources.

After the industrial revolution, fossil fuels were used extensively in various countries around the world. With the development of science and technology, the use of nuclear energy has become more and more popular. However, the use of these energy sources has caused great environmental impacts, including the leakage of nuclear energy and the greenhouse effect caused by a large amount of carbon dioxide emissions. The average temperature rises, and the acid rain caused by the combination of the exhaust gas and the rainwater causes environmental pollution, a large number of biological deaths, and great changes in the climate. The cause and effect planted in the past 100 years will eventually return to people.

At the same time, in recent years, humans have begun to think about replacing non-renewable energy with renewable energy, including hydropower, wind power, geothermal energy, ocean energy, waste conversion, solar energy and biomass energy. However, in the process of renewable energy research and development, technical impureness and raw materials. Problems such as sources have led to a rate of regenerative energy use that does not meet the expected ideal value.

The development of renewable energy and the move to a low-carbon society is an inevitable trend. Therefore, in the future power system, it is necessary to reduce the proportion of petrochemical energy and expand the use of renewable energy. Since most of the renewable energy is intermittent energy, it is small and scattered. The characteristics of the system are different from the current high-concentration centralized power generation system. In the future, the power system is bound to strengthen the decentralized power supply and area. Grid technology can meet the challenges and needs of the future.

At present, the microgrid integrates a series of loads and power generation into a single Controllable system, providing power and heat, mainly composed of micro power supply, power equipment, static switch and automatic monitoring system; micro grid can be operated in parallel with large power grid, and the power supply and demand in the micro grid is balanced by the large power grid. When the grid is faulty, it can also operate independently.

The actual application scenarios of microgrids must integrate power transmission and capital communication control. And energy management technologies [such as power generation forecasting, load forecasting and energy dispatching] can integrate the supply status of distributed power sources according to daily power demand and price changes.

However, although countries are now investing in decentralized energy microgrid technology, In recent years, it has invested heavily in technology development. However, there is no proprietary technical specification, which leads to the lack of interchangeability and sharing of related equipment, lack of system integration, and the need to re-evaluate and design microgrids for each additional power generation system. The cost is high, the application is low, and most importantly, although the overall power consumption can be reduced, the performance is still limited, consumers are less sensible, and it is difficult to enjoy the actual benefits. Currently, solar power systems usually have It is not only time-consuming but also costly to apply for signing procedures and installation and construction of power generation systems.

In view of this, how to provide a kind of application that is easy to apply, low in construction cost, is different from The traditional micro-grid and the grid-connected power grid, and the multi-group multi-zone mutual-assisted power generation system that enables consumers to truly feel the improvement of overall performance and economic efficiency has become a subject of improvement of the present invention.
