论文摘要
随着澳大利亚的大量家庭光伏能力,电池成本的降低可能会导致广泛使用家庭光伏电池系统。由于这些系统的采用受零售关税的影响很大,因此本文分析了纯零售关税的影响,家庭可以自由投资PV电池系统。使用澳大利亚的珀斯在上下文中,开源模型用于模拟20年内的家用光伏电池投资。我们发现,随着家庭从只有PV的过渡到PV玻璃系统的过渡,持平的使用和馈电关税会导致不同的剩余需求模式。从自下而上分析这些模式,我们确定可能挑战未来电力系统管理,市场参与和能源政策的转化点过渡。继续使用扁平关税会激励光伏式家庭以最大程度地提高自我消费,从而减少年度网格进口量,增加年度网格出口,并将剩余需求转移到冬季。随着光伏棒家庭最终成为净产生者,昼夜和季节性需求模式继续发生变化。这些自下而上的变化不受管理,可能会使集中电力市场中的能源脱碳工作复杂化,并表明政策制定者应该为PV棒家庭做准备,以便在能源系统中发挥更积极的作用。
With Australia's significant capacity of household PV, decreasing battery costs may lead to widespread use of household PV-battery systems. As the adoption of these systems are heavily influenced by retail tariffs, this paper analyses the effects of flat retail tariffs with households free to invest in PV battery systems. Using Perth, Australia for context, an open-source model is used to simulate household PV battery investments over a 20-year period. We find that flat usage and feed-in tariffs lead to distinct residual demand patterns as households' transition from PV-only to PV-battery systems. Analysing these patterns qualitatively from the bottom-up, we identify tipping point transitions that may challenge future electricity system management, market participation and energy policy. The continued use of flat tariffs incentivises PV-battery households to maximise self-consumption, which reduces annual grid-imports, increases annual grid-exports, and shifts residual demand towards winter. Diurnal and seasonal demand patterns continue to change as PV-battery households eventually become net-generators. Unmanaged, these bottom-up changes may complicate energy decarbonisation efforts within centralised electricity markets and suggests that policymakers should prepare for PV-battery households to play a more active role in the energy system.
