And the steam turbine generator is electrically connected with the power grid. Electricity-heat-electricity energy storage power generation that heat energy is generated by electric energy and then power is generated is achieved, the electric power safety supply guarantee risk and the electric power system safety and stability risk are reduced, and the pressure problem of clean energy consumption is solved.

Description

technical field [0001] The invention relates to the technical field of energy storage and power generation, in particular to a system and method for supersonic frequency electromagnetic induction heating binary salt energy storage and power generation. Background technique [0002] With the proposal of the goal of "carbon peak and carbon neutrality", the scale of development and utilization of renewable energy will continue to expand, and will become the key to realizing low-carbon energy transformation in the future. However, compared with traditional fossil energy power generation, renewable energy power generation based on wind energy and solar energy is dependent on natural conditions and has the characteristics of volatility and intermittency. Large-scale integration will bring great impact to the security and stability of the grid. impact, thus leading to difficulties in wind power and photovoltaic grid connection and consumption, and severe wind and solar curtailment....
