分布式光伏（PV）电池系统最近受到世界各地消费者的高度关注。光伏电池系统使消费者能够以更低或同等的成本减少对当地电力供应商的依赖。然而，光伏电池系统的盈利能力在很大程度上取决于当地的气象条件和当地的零售电价。在中欧国家，由于光照较低，光伏电池系统在冬季发电和储存的电力较少。特别是，可以保留电池在冬季提供辅助服务，从而提高整个系统的经济性。在本研究中，使用由各个负载曲线组成的大型数据集来模拟虚拟发电厂，该发电厂在电池闲置期间提供辅助服务。结果表明，拥有大型电池的参与者可以通过参与储备市场来大大提高其整体系统经济性。然而，电池容量较小的参与者可能无法收回与虚拟发电厂通信的额外成本，因此不适合提供电网稳定服务（辅助服务）。
Decentralized photovoltaic (PV) battery systems have recently received great attention from consumers around the world. PV battery systems allow consumers to reduce their dependence on the local electricity supplier at lower or equivalent costs. However, the profitability of PV battery systems depends greatly on the local meteorological conditions and the local electricity retail tariff. In central European countries, PV battery systems generate and store less electricity in winter months due to lower irradiation. The battery, in particular, can be reserved to provide ancillary services during winter months and thereby improves the overall systems economics. In this study, a large dataset consisting of individual load profiles is used to simulate a virtual power plant which provides ancillary services during battery idle times. The results show that participants with large batteries can greatly increase their overall systems economics by participating in reserve markets. However, participants with small battery capacities may not be able to recover the additional costs for communication with the virtual power plant and are thus not suitable candidates to provide grid stabilizing services (ancillary services).
