Due to the increased awareness of environmental protection and the possible pollution caused by thermal power generation, research on hydro-related multi-energy complementary power generation has emerged. In this article, we used literature analysis software to analyze the relevant literature of our research object to fully understand its research status. Results show that the use of hydro-related multi-energy power generation is the current research trend for maximizing profits, reducing losses and so on. In the future, the design, operation and optimization research of multi-energy power generation systems related to hydro, especially hydro, wind and solar energy will be important development trends.

Research status and future of hydro-related sustainable complementary multi-energy power generation

Hydropower generation from the Qattara depression has been subject to thorough investigations during the last five decades. The general conclusion reached was that the project has rather low benefits in comparison with its cost. This was mainly attributed to the exorbitant cost of channeling sea water into the depression. In the latter juncture, it was found that using nuclear excavation would substantially reduce the expenses; however, such a solution was rejected on ecological grounds. The present approach to the project is aimed at escalating its benefits, by incorporating an integrated system of solar ponds for base load. In the present context, the heat extracted from the solar ponds is used to operate thermal power plants that will follow a novel cycle of the Rankine type. The new method arrived at will enable the simultaneous production of electricity and fresh water. Despite the fact that the combined hydro-solar arrangement leads to augmenting the benefits to cost ratio by at least 21%, ...
