Problems solved by technology
Due to the significant intermittency, volatility and randomness of renewable energy power generation, the power system is facing challenges such as low overall efficiency, insufficient coordination of sources, grids and loads, and insufficient complementarity and mutual assistance of various power sources.
Based on the new pattern of energy supply and demand, the traditional peak-shaving mechanism of thermal power units can no longer meet the new requirements of the power system for power-side flexibility

The invention provides an energy storage power generation system. The energy storage power generation system comprises a boiler comprising a first heat exchange jig, a steam turbine comprising a turbine proper and a second heat exchange rig, and a plurality of fused salt circulating systems, wherein the fused salt circulating systems are arranged between the boiler and the turbine proper and are configured to transfer heat generated by the boiler to an acting working medium of the turbine proper so that the working medium can drive the turbine proper to rotate, and different fused salt circulating systems adopt fused salt of different components as heat exchange media; and the fused salt circulating systems are thermally coupled with the boiler through the first heat exchange jig, the fused salt absorbs heat from the boiler through the first heat exchange jig, the fused salt circulating systems are thermally coupled with the turbine proper through the second heat exchange jig, and the fused salt releases heat to the acting working medium of the turbine proper through the second heat exchange jig. According to the energy storage power generation system, flexible operation of a thermal power generating unit under different loads can be realized.
Description
technical field [0001] The present disclosure relates to the technical field of coal-fired power generation, in particular to an energy storage power generation system. Background technique [0002] With the implementation of my country's new energy security strategy and new development concept, the energy transformation is further promoted, the large-scale continuous integration of renewable energy power generation into the grid, the proportion of renewable energy power generation continues to increase, and the utilization hours of thermal power units continue to decline. Due to the significant intermittency, volatility, and randomness of renewable energy power generation, the power system faces challenges such as low overall efficiency, insufficient coordination of sources, networks, and loads, and insufficient complementarity and mutual assistance of various power sources. Based on the new pattern of energy supply and demand, the traditional peak regulation mechanism of t...
