电力系统的快速和深度脱碳对于到2050年实现净零排放的许多途径至关重要。智能本地能源系统（SLES）被吹捧为快速扩大可再生电力规模和灵活稳定脱碳电力系统的关键。本文采用了一种新的基于主体的模型——结合了当地投资者和治理主体、改进的时间解决方案和需求侧灵活性——来研究SLES规模扩张中的战略决策。从该模型的角度来看，关键的建模见解包括：SLES投资者最初得到地方政府的支持，可以成功地将可再生能源的吸收提高到总发电量的80%；SLES的扩大严重侵蚀了现有公用事业公司的市场份额和盈利能力，但国家一级的代理商仍然是资本密集型低碳电厂的关键；需求侧响应有助于平衡电力供需，但它可能导致非最优政策主体推迟对异质投资者主体建设新的低碳电厂的必要激励；需要国家碳价格（与地方SLES和技术支持机制相结合）来维持整个系统的稳定。因此，理解非最优投资者决策的关键作用是充分理解SLES快速扩大的驱动因素和影响的关键。
Rapid and deep decarbonisation of electricity systems is critical in many pathways to meet net-zero emissions by 2050. Smart local energy systems (SLES) have been touted as key for both a rapid scale-up of renewable electricity and flexibility for stability in decarbonised electricity systems. A novel agent-based model – incorporating local investor and governance agents, improved temporal resolution, and demand-side flexibility – was used to investigate strategic decision making in the scale-up of SLES. From the perspective of this model, key modelling insights include: SLES investors, initially supported by local governments, can successfully boost the uptake of renewable energy up to 80% of total generation; SLES scale-up significantly erodes the market share and profitability of incumbent utilities, however national level agents are still key for capital-intensive low carbon plants; Demand-side response facilitates balancing electricity supply and demand, but it can result in non-optimal policy agents postponing required incentives for heterogeneous investor agents to build new low carbon plants; National carbon prices (in conjunction with local SLES and technology support mechanisms) are needed to maintain overall system stability. Therefore, understanding the critical role of non-optimal investor decision making is key to fully understand the drivers and implications of a rapid scale-up of SLES.
