使用热泵（hp）和电动汽车（ev）的热量和运输的脱碳将需要在低压（LV）网络方面进行大量投资，无论是在网络加固方面，还是在提供灵活性以避免网络升级方面。在本文中，提出了一种启发式方法来估计在不同hp渗透率下低压网络中国内电动汽车充电优化的可用净空空间，并将一种新的区域方法应用于电动汽车优化。研究发现，对于给定的HP渗透率，优化的电动汽车充电可以使电动汽车的渗透率显著提高，而无需加固。在网络托管容量方面实现了重大改进：例如，在一个特定的案例研究中，从哑充电的34% EV和50% HP渗透率增加到优化充电的72% EV和57% HP渗透率。研究发现，托管能力的改善程度强烈依赖于特定的网络拓扑结构和预先存在的需求；这加强了进一步研究的必要性，以解锁电动汽车和HP摄取的潜在协同作用。
The decarbonisation of heat and transport using heat pumps (HPs) and electric vehicles (EVs) will require significant investment in low voltage (LV) networks both in terms of network reinforcement and in the provision of flexibility to avoid network upgrades where appropriate. In this paper, a heuristic methodology is presented to estimate headroom available for domestic EV charging optimisation in LV networks at different penetrations of HPs and a novel zonal approach is applied to EV optimisation. It was found that optimised charging of EVs can allow for a significantly higher penetration of EVs for a given HP penetration within the network, without the need for reinforcement. Significant improvements in terms of network hosting capacity were realised: for example, an increase from 34% EV and 50% HP penetration for dumb charging to 72% EV and 57% HP penetration for optimised charging was available for one particular case study. The level of improvement in hosting capacity was found to be strongly dependent on particular network topology and pre-existing demand; this reinforces the need for further study in unlocking the potential synergies of EV and HP uptake.
