Capacity Credit Assessment of Cyber Physical Power System Considering Climate Change

The cyber-physical power systems (CPPS) are highly coupled with the physical power systems and the information systems. Therefore, the reliability evaluation of the CPPS needs to consider the impact of cyber-attacks or communication failures. Climate-induced temperature increases have an effect on both load demand and energy supply systems, which can lead to a drop in power system reliability. Thus, this paper presents a capacity credit assessment framework to evaluate the effect of climate change and multiple storage technologies on cyber-physical power system adequacy. First, the effects of information system failures on physical systems are modeled. The effects of climate change on electricity consumption, power generation, and power infrastructure are modeled. Second, this paper proposes a coordinated dispatch approach to address the computational burden attributed to the temporal coupling features of energy storage. Thirdly, a capacity credit (CC) assessment framework combining a multi-time-scale dispatch approach of energy storage is developed to model the effect of climate change and communication failures on the capacity credit of renewable energy. Finally, the proposed method is validated by the provincial power system of Guangxi (GX).
