Description
Summary:Small-scale multi-source energy systems that accommodate distributed energy resources are increasingly serving the demand for efficient low-carbon energy systems. This paper investigates the relationship between carbon reduction targets and the optimal design and scheduling of a small-scale multi-source energy system based on an energy hub model. A Monte Carlo simulation is conducted to represent the uncertainty of solar power generation, and reliability indices (loss-of-load expectation and expected energy not served) are considered to ensure a reliable energy supply within the system. The simulation results show a considerable change in the optimal energy resource mix corresponding to different carbon reduction targets in both the grid-connected and isolated systems, as well as the essential role of electrical energy storage in maintaining reliability. •Impacts of carbon reduction targets on energy system planning are investigated.•An energy hub model represents combined heat and power system characteristics.•System reliability is considered under uncertain solar power generation.•Different carbon reduction targets are found to change the optimal resource mix.
