基于可再生能源的能源系统需要增加需求方的灵活性。此外，基本成本结构的变化，即，可变成本的降低和基础设施投资的增加以及消费者需求的变化应反映在未来市场的建立中，包括零售市场和关税。虽然各种研究仅关注可变能源价格的电价，以利用住宅需求侧的灵活性，但我们在分析中将电价与基于容量的价格成分结合起来。后者使电力供应商能够提供更有区别的电价，考虑到个人消费者的需求和平衡的成本分配。为了比较不同电价对居民需求侧灵活性的影响，我们建立了一个自下而上的负荷模型。该模型不仅模拟，而且还优化了住宅负荷分布在不同的关税。该模型是根据大规模田间试验的数据进行校准的。我们的研究结果表明，可变能源价格的关税诱导更大的需求侧灵活性，但从供应商的角度来看，可变容量价格的关税的影响是更可预测和可靠的。确定了潜在的监管调整，以实现可持续的商业模式，奖励需求方的灵活性，并促进技术实施。
Energy systems based on renewable energy sources require increasing demand side flexibility. Also, changes in the underlying cost structure, i.e., decreasing variable costs and increasing infrastructure investments as well as varying consumer needs should be reflected in the setup of future markets, including retail markets and tariffs. While various studies focus solely on tariffs with variable energy prices to leverage residential demand side flexibility, we incorporate tariffs with capacity-based price components in our analysis. The latter enable electricity providers to offer more differentiated tariffs, considering individual consumer needs and a balanced cost allocation. To compare the impact of different tariffs on residential demand side flexibility, we develop a bottom-up load model. This model not only simulates but also optimizes residential load profiles in the presence of different tariffs. The model is calibrated based on data from a large-scale field trial. Our results show that tariffs with variable energy prices induce larger demand side flexibility, but the impact of tariffs with variable capacity prices is more predictable and reliable from a suppliers perspective. Potential regulatory adjustments are identified enabling sustainable business models, rewarding demand side flexibility and facilitating the technical implementation.
