Research on Combined Optimal Dispatch Model of Nuclear-Thermal-Energy Storage with Nuclear Power Participating in Equivalent Peak Load Regulation

With the increasing peak-valley difference of power grid and the increasing proportion of nuclear power supply structure, it is imperative for nuclear power to participate in Peak load regulation of power system. This article proposes a combined optimal dispatch model of nuclear-thermal-energy storage with nuclear power participating in equivalent peak load regulation. By the energy transfer capacity of heat storage device, the amount of the nuclear power participating in the peak load regulation is consumed, and the output of other units is optimized. Therefore, the equivalent peak shaving of the nuclear power unit is realized under the full power output. Examples show that the model can achieve the equivalent peak load regulation of nuclear power can save the cost of power generation, and the pollution gas emissions are reduced, so it ensures the economy and security of power grid operation.
