Power generation:coal-fired power plants, gas-fired power plants, nuclear power plants Power grid: on average, 2/3 of the primary energy is wasted or consumed during the transmission process.
Infrastructure aging
Environmental constraints: increased carbon emissions affect global climate change; increased air pollution and medical costs; water waste and pollution.
The economically recoverable reserves of coal have decreased drastically.
New security considerations
Nuclear power: the financing challenge of nuclear power: the more nuclear power plants are built, the higher the cost of new construction.
Coal
Summary: nuclear power and “clean coal” not only lack investment attractiveness, but also lack operational flexibility to ensure the smooth integration of renewable energy power.
Rich renewable resources: wind energy, biomass energy, water energy, solar energy (photovoltaic, thermal power generation), geothermal energy, tidal energy, wave energy.
Cost has passed the critical point: the installed scale and production scale of wind energy and solar energy at home and abroad have been expanded, and the price has been reduced.
Power grid is stable, power system flexibility is high Energy storage technology.
Large-scale transmission system
A single, top-down power grid will change to a personalized, differentiated and user-centered way.
The trend of integration of innovation will provide the foundation and impetus for the centralized grid structure beyond the Edison era to reach the revolutionary era.
- Distributed generation decentralized.
- Microgrid distributed batteries.
- Super capacitors, super conducting rings, etc.
Generation: high voltage transmission system, low voltage distribution system.
Energy-saving
Smart Grid: a large number of technologies and applications for advanced communications, information and control services for power companies and consumers.
