Table 1. Summary of the island microgrids. Recently, three unique stand-alone microgrid projects have been built at Dongfushan Island, Nanji Island, and Beiji Island in the east China, with an aim to replace diesel with renewable energy to improve renewable energy utilization, enhance power supply reliability, and reduce power supply cost.
Key technologies such as control technology and energy management for island microgrids are studied. Renewable energy penetration is discussed for the design and operation of island microgrids. The operation data for a year of the three island microgrids are analyzed from various aspects.
Three representative island microgrids in the East China Sea are demonstrated. Key technologies such as control technology and energy management for island microgrids are studied. Renewable energy penetration is discussed for the design and operation of island microgrids.
The presence of such systems in microgrids causes power balance inconsistency, leading to increased power losses and deviation in voltage. In this paper, a mixed-integer non-linear programming model is proposed for modelling island microgrid energy management considering smart loads, clean energy resources, electric vehicles and batteries.
Overall, the paper presents a comprehensive approach to the optimal management of island microgrids. The approach involves reducing losses and pollution, and improving voltage while maximizing the use of renewable resources.
