Problems solved by technology
[0002] The power supply of islands far away from the land mostly uses independent microgrids for power supply, and the current research on optimal dispatching of microgrids is mainly carried out for inland microgrids. Inland microgrids do not include ocean energy power generation and do not involve island load characteristics, so The proposed microgrid energy optimization scheduling method is not suitable for island microgrid systems

The invention discloses an island microgrid energy optimization scheduling method which comprises the following steps of: constructing an island microgrid energy optimization scheduling model by taking island economy as a target; making a day-ahead scheduling plan according to ocean energy power generation and island load characteristics; and comparing the day-ahead scheduling plan with an intra-day real-time rolling calculation result, correcting the day-ahead scheduling plan according to a comparison result and an intra-day real-time flow calculation result, and obtaining a current-day island microgrid energy scheduling optimization scheme. The problem that an existing microgrid energy optimization scheduling method is not suitable for an island microgrid system is solved.
