高比例新能源电力系统演化进程中核电与新能源协调发展策略

核能与新能源作为非化石能源的重要组成部分，对于中国构建清洁低碳、安全高效的能源体系具有举足轻重的作用。随着大规模间歇式新能源接入电力系统，电网的安全稳定运行面临巨大挑战，核电出力稳定、转动惯量大，可为高比例新能源接入的电力系统提供必要的电力、电量和转动惯量支撑。针对高比例新能源电力系统演化进程中核电、新能源及其他电源的协调发展问题，统筹考虑系统规划与运行层面的相互影响，基于电力系统规划软件GESP及电力系统随机生产模拟软件GridView，建立一套完整的分析模型，提出中国未来核电与新能源的合理发展规模和布局；考虑核电与其他电源以不同方式参与电网调峰对新能源消纳及系统运行经济性等方面的影响，提出促进核电与新能源协调运行的策略建议，为促进中国核电与新能源有序健康发展、深入推动能源转型提供决策支撑。

Coordinated Development Strategy for Nuclear Power and New Energy in the Evolution Process of Power System with High Penetration of New Energy

As important components of non-fossil energy, the nuclear energy and new energy are playing a significant role in constructing the clean, low-carbon, safe and efficient energy system in China. With large scale integration of new energy, the power system is confronted with enormous challenges in safe and stable operation. Nuclear power is stable in output and large in moment of inertia, which can provide necessary power, electricity and inertia support for the power system with high penetration of new energy. For coordinated development of nuclear power, new energy and other power sources in the evolution process of power system with high penetration of new energy, and with consideration of the mutual effects of system planning and operation, this paper establishes a complete set of analytical models based on the mid-long term power planning model (GESP) and the stochastic production simulation model of power system (GridView). It also proposes the reasonable development scale, structure and layout of nuclear power and new energy in China. Considering the influence of nuclear power and other power sources participating in power grid peak regulation with different modes on new energy accommodation and system operation economy, some strategic suggestions are proposed to promote the coordinated operation of nuclear power and new energy, which may provide a decision-making support for promoting orderly and healthy development of nuclear power and new energy, and advancing the energy transformation in China.
