Abstract

The fluctuation nature of renewable energy causes the imbalance between energy demand and supply. The nuclear-renewable hybrid energy system (NRHES) that couples renewable energy with a small modular thorium molten salt reactor (smTMSR), thermal energy storage (TES), and high-temperature steam electrolysis (HTSE) is constructed to solve this problem. Three operation modes (Mode 1: NRHES without HTSE, Mode 2: NRHES coupled with HTES, Mode 3: NRHES coupled with HTES with limiting condition) with different energy management strategies are proposed and compared firstly in current research. The multi-objective particle swarm optimization (MOPSO) with better performance is chosen to conduct multi-objective capacity configuration optimization of the NRHES. The optimization objectives include minimizing deficiency of power supply probability (DPSP), energy waste possibility (EWP), and levelized cost of energy (LCOE). The three-dimensional Pareto solutions are obtained and the mode 3 is demonstrated to be the optimal mode. The results analysis shows that the addition of HTSE with limiting condition could increase proportions of power supply and hydrogen production of nuclear energy, which reduces the wasted energy naturally. This study provides valuable reference information for relieving the imbalance of energy supply and demand in NRHES effectively.

基于smtmsr的高温蒸汽电解核可再生混合能源系统的技术经济评价

可再生能源的波动性导致能源供需失衡。为解决这一问题，构建了将可再生能源与小型模块化钍熔盐堆（smTMSR）、热能储存（TES）和高温蒸汽电解（HTSE）相结合的核-可再生混合能源系统（NRHES）。首先提出了三种不同能量管理策略的运行模式（模式1：无HTSE的NRHES、模式2:NRHES与HTES耦合、模式3：有限制条件的NRHES与HTES耦合），并对其进行了比较。选择性能较好的多目标粒子群算法（MOPSO）对NRHES进行多目标容量配置优化。优化目标包括电力供应不足概率（DPSP）、能源浪费可能性（EWP）和能源平准化成本（LCOE）最小化。得到了三维Pareto解，并证明了模态3是最优模态。结果分析表明，有极限条件的HTSE的加入可以提高核能的供电和产氢比例，自然地减少了能源浪费。该研究为有效缓解NRHES能源供需失衡提供了有价值的参考信息。
