How many types of energy complementary power generation are there?

At present, there are the most researches on two types of energy complementary power generation, such as hydro-wind and hydro-solar power generation, especially hydro-thermal power generation. However, research on power generation systems including three or four types of energy is relatively low.

What is multi-energy complementary power generation system?

Multi-energy complementary power generation system refers to the use of multiple energy sources to complement each other to generate electricity, to make up for their shortcomings, and to achieve cost reduction or power generation efficiency. There are various energy combinations for complementary power generation.

What is a complementary power generation system?

The complementary power generation system composed of renewable resources and conventional resources has received extensive attention and studies by researchers. For example, the hydro-thermal, hydro-wind, hydro-solar, wind-solar systems and so on. However, research on the hydro-thermal-wind-solar is relatively rare compared to others.

Can wind and solar energy be integrated into a zero-energy building?

Deymi-Dashtebayaz et al. integrated wind and solar energy into a nearly zero-energy building. The integrated system could realize power supply, heating and cooling. The feasibility of the system was studied from the perspectives of energy, economy and environment.

Should solar energy be integrated with coal-fired power plants?

The integration of solar energy and conventional coal-fired power plants can rise the power generation efficiency, reduce the use of coal, supplement some of the defects of single CSP system and improve the environment to a certain extent.

Are city-level off-grid PV-hydro complementary power systems feasible?

Conclusions and future directions The feasibility of the city level off-grid PV-hydro complementary power systems is verified by the reasonable design and operation plan of the studied case.
