Embodiment Construction

[0077] The present invention will be further described below in conjunction with accompanying drawing.

[0078] like figure 1 As shown, in the island new energy multi-microgrid system, the internal structural units of the microgrid system are mainly:

[0079] 1) Distributed power generation: In the island microgrid, distributed power generation (DG) mainly includes wind power and photovoltaic power generation, and renewable energy power generation is the main power generation method. Its power generation is determined by real-time weather conditions, and it can be predicted for a certain period of time by using appropriate forecasting methods.

[0080] 2) Load: Through the load forecasting method, after considering various factors such as user type, temperature, and holidays, the load demand within a certain period of time can be predicted. When the power supply is tight, part of the load can be shed to maintain system operation.

[0081] 3) Energy storage device: In the of...

Abstract

The invention relates to a nearby-island multi-microgrid dynamic scheduling method based on MCS-PSO. At present, the research for the multi-microgrid interconnection technology is intensive step by step. However, the research for multi-microgrid active scheduling is less. On the basis of generation and load prediction, an optimization model for each microgrid interconnection line power control is built on the basis of the indexes of reliability and economy, and the solution is carried out through the MCS-PSO. Due to the fact that generation and load prediction information in microgrids is constantly updated as time goes by, dynamic optimization scheduling updated in an online-rolling mode is adopted so as to improve the precision of a scheduling plane. According to the nearby-island multi-microgrid dynamic scheduling method based on the MCS-PSO, by the combination of the reality of interconnection operation of multiple nearby islands, energy of the microgrid of each island can be reasonably scheduled and distributed, various uncertainty factors are fully taken into account, and the running cost and loss can be reduced to the minimum.

Description

technical field [0001] The invention belongs to the technical field of power systems, and in particular relates to an MCS-PSO-based dynamic scheduling method for multiple microgrids adjacent to sea islands. Background technique [0002] The development of distributed power generation and microgrid technology provides new ideas for solving the power supply problem in remote areas of my country. The development of micro-grid can not only effectively develop and utilize local renewable energy, but also solve the problem of power supply in remote areas. For an isolated microgrid without the support of the main grid, due to the volatility and randomness of wind and solar resources, it is necessary to rely on the energy storage system to maintain the balance between power generation and load, and its power supply reliability is limited by its own regulation ability. [0003] The regional interconnection operation of the large power grid can provide mutual power supply and backup ...
