Risk-aware Resistance Enhancement of Combined Heat and Power Supply Under Cold Extremes

Résumé fourni par la source

Cold extremes bring significant uncertainties to the energy system. Their strong spatiotemporal coupling introduces growing challenges to the adequacy and flexibility of the power and heating supply, complicating risk identification and mitigation. Therefore, this paper presents a framework for spatiotemporal risk assessment and resistance enhancement under cold extremes. It captures cold-air propagation using a trajectory-informed method and quantifies the inadequacy of the heating supply through multiple risk indicators. Based on this, a risk-aware scheduling strategy is developed to improve the coordination of power and heating supply and enhance system adaptability during cold extremes. Empirical studies on the biomass-based combined heat and power supply in Sweden demonstrate the effectiveness of the proposed approach in reducing heating supply inadequacy and external energy dependence.
