发电技术的系统集成成本（SIC），也称为系统外部性，包括系统中产生的各种类型的额外成本，以及增加到系统中的发电能力的建设和运营成本。SIC可能包括增加的平衡成本、额外备份容量的成本、加强网络基础设施的成本以及维持系统碳排放的成本。在本文中，我们提出了一种量化SIC的全系统方法，并探索了计算发电技术与另一种技术相比的相对SIC的不同方法。结果表明，低碳发电技术的SIC将显着取决于发电组合的组成，具有较高的渗透率的可变可再生能源产生较高的SIC。此外，SIC将在很大程度上取决于灵活选项的部署水平，如更灵活的发电技术、能源储存、需求侧响应或互连。由低碳技术驱动的额外系统成本可以为能源政策提供非常有用的信息，并支持选择具有最低总系统成本的低碳组合。
System integration costs (SIC) of generation technologies, also referred to as system externalities, include various categories of additional costs that are incurred in the system in addition to the cost of building and operating the generation capacity that is added to the system. SIC may include increased balancing cost, cost of additional backup capacity, cost of reinforcing network infrastructure and the cost of maintaining system carbon emissions. In this paper we present a whole-system approach to quantifying the SIC and explore different approaches to calculating the relative SIC of a generation technology when compared to another technology. The results show that the SIC of low-carbon generation technologies will significantly depend on the composition of the generation mix, with higher penetrations of variable renewables giving rise to a higher SIC. Also, SIC will significantly depend on the deployment level of flexible options such as more flexible generation technologies, energy storage, demand side response or interconnection. The additional system cost driven by low-carbon technologies can provide a very useful input to inform the energy policy and support the selection of the low-carbon portfolio with the lowest total system cost.
