What are the island microgrids?
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.
Are island microgrids reliable?
As many island micro grids are not connected with the continent [ 1, 2, 3 ], distributed renewable power and generators have become the major sources of island power supply. Hence, the reliability of island microgrid would be affected by random variability of renewable energy and loads [ 4, 5 ].
Does a microgrid have load shedding?
In all cases, there is no load shedding (0 MW), indicating that the microgrid can meet its entire load demand even during renewable energy outages. These values represent the total power generated by photovoltaic (PV) and wind sources, respectively.
What is the optimal scheduling model for Island microgrid?
Then, to reach the goal of economic dispatch, an optimal scheduling model of island microgrid is established with the consideration of both respective operation constraints and island load requirements. Finally, the effectiveness of the proposed model is verified by an island microgrid over two typical seasons.
