Optimized operation of port hybrid energy system considering the trade-off between resilience and peak shaving

In view of the current lack of “resilience and peak shaving” trade-off methods for port energy storage and the poor recovery ability of shore power systems in response to emergencies, an optimized operation method for port hybrid energy systems that considers the “resilience-peak shaving” trade-off is proposed. Based on the resilience characteristics of shore power loads, a resilience window algorithm is proposed to determine the resilience energy storage during peak periods, improve the peak shaving effect of the system, reduce operating cost, and ensure the normal operation of shore power. The case analysis shows that this method improves the peak shaving effect of the system by 2.04% and reduces operating cost by 1.19%, which is of significance for improving the economic and safety performance of port hybrid energy system operation.
