论文摘要
研究已使用优化方法评估了100％可再生能源系统的经济可行性，但是确定结果的机制仍然很少了解。基于一个简单但必不可少的模型，这项研究发现，需求和发电概况之间最大的不匹配形成的瓶颈决定了发电和存储的最佳能力及其权衡关系。本研究采用微观经济学理论，尤其是数量和价值的双重性，全面量化了技术成本，最佳能力和总系统成本之间的关系。使用日本多年/地区的实际概况数据，这项研究表明，包括成本竞争性的多个可再生能源和不同类型的存储组成的混合系统对于任何概况的经济可行性至关重要。
Studies have evaluated the economic feasibility of 100% renewable power systems using the optimization approach, but the mechanisms determining the results remain poorly understood. Based on a simple but essential model, this study found that the bottleneck formed by the largest mismatch between demand and power generation profiles determines the optimal capacities of generation and storage and their trade-off relationship. Applying microeconomic theory, particularly the duality of quantity and value, this study comprehensively quantified the relationships among the factor cost of technologies, their optimal capacities, and total system cost. Using actual profile data for multiple years/regions in Japan, this study demonstrated that hybrid systems comprising cost-competitive multiple renewable energy sources and different types of storage are critical for the economic feasibility of any profile.
