Impact Assessment of Heat Waves on Resilience of Power System Components

Heat waves is a significant climatic phenomenon exerting profound effects on society, agriculture, the environment, and crucially, the power sector. This study aims to assess the impact of heat waves on power system components, particularly transmission lines and generators. A normal distribution model is employed to synthesize the historical heat wave data for a period of 10 years and applied to the IEEE 57-bus transmission test system. The resilience of the system components is determined in terms of impact of heat wave on the capacity of transmission lines and power generation output which are temperature-dependent. The resilience is also investigated for base case loading and overloading conditions during heat waves. The other key parameters such as Available Transfer Capability (ATC), system losses, remaining generator capacity, and generation cost are also evaluated to provide an insight into the power system's component resilience under heat wave conditions.
