Abstract

The invention discloses an energy optimization scheduling method for a microgrid containing distributed wind power. The method comprises the following steps of constructing an optimization schedulingmodel for the microgrid containing the distributed wind power; carrying out MPC optimal scheduling on the optimization scheduling model for the microgrid; obtaining a random scene model according to the optimization scheduling model for the microgrid; obtaining the constraint conditions of the optimization scheduling model for the microgrid; and solving the random scene model meeting the constraint conditions. According to the energy optimization scheduling method for the microgrid containing distributed wind power provided by the present invention, a typical microgrid system and a solving framework based on model prediction control are constructed, the problem of joint scheduling of random renewable energy sources and storage battery energy storage in the microgrid is effectively solved,and through the optimization operation model for the microgridprovided by the invention, the economic operation of the microgrid is realized, and meanwhile, the randomness and robustness of the modelare studied through simulation.

Description

technical field [0001] The invention belongs to the technical field of micro-grids, and in particular relates to a micro-grid energy optimization scheduling method including distributed wind power. Background technique [0002] Clean and low-carbon has become the development trend of global energy transformation. The energy revolution characterized by the deep integration of new energy and information technology is pushing human society into a new energy system. A series of problems such as source-load imbalance, as of the end of 2018, my country's solar and wind energy grid-connected installed capacity reached 360 million KW, accounting for 19% of the installed capacity, but the power generation accounted for only 7.8% of the total, and the problem of wind and solar abandonment is still serious. The concept of Energy Internet has become a good solution to the above problems and the key to energy transformation. Microgrid, as an advanced stage of distributed power generation,...
