分布式储能（DES）在未来电网中的发展受到可再生能源的整合、电网灵活性要求以及能源独立性需求等因素的推动。电网运营商已经发布了未来的能源情景，预测DES的广泛采用，促使需要调查其在不同的操作模式下的影响。本研究发展个案模式，并进行个案研究，以全面探讨其意涵。研究结果强调了协调DES运行的重要性，以解决电网问题并减轻高二氧化碳（CO2）排放期间的收费。不协调的DES操作可能导致重大的电网挑战和高排放影响。相反，当DES以协调的方式聚合和运行时，它表现出缓解电网问题和避免在高排放时间充电的潜力。该研究强调了DES利润、网络加固成本和CO2排放之间的权衡。考虑网络加固成本对DES聚合器利润有13%的负面影响，而考虑CO2成本可能导致35%的更大降幅。这些研究结果强调，需要适当的监管和政策实施，以确保DES聚合器的充分补偿，并激励协调潜力，同时平衡这些目标之间的权衡。
The growth of distributed energy storage (DES) in the future power grid is driven by factors such as the integration of renewable energy sources, grid flexibility requirements, and the desire for energy independence. Grid operators have published future energy scenarios projecting the widespread adoption of DES, prompting the need to investigate its impact under different operational modes. This study develops case models and conducts case studies to explore the implications comprehensively. The findings highlight the importance of coordinating the operation of DES to address grid issues and mitigate charging during high carbon dioxide (CO2) emissions periods. Uncoordinated DES operation can lead to significant grid challenges and high emissions impacts. Conversely, when DES is aggregated and operated in a coordinated manner, it demonstrates the potential to alleviate grid problems and avoid charging during high-emission hours. The study highlights the existence of trade-offs among DES profit, network reinforcement cost, andCO2emissions. Accounting for the network reinforcement costs has a 13% negative impact on DES aggregator profits, while accounting forCO2costs could lead to a larger decrease of 35%. These findings highlight the need for proper regulation and policy implementation to ensure adequate compensation for DES aggregator and incentivise the coordination potential while balancing the trade-offs among these objectives.
