摘要

With the development of the national economy, people's demand for electricity continues to increase, but in some remote areas such as islands and mountain areas, it is usually far away from the conventional large power grid, and it is difficult to get a good power supply. These areas generally contain abundant renewable energy, such as wind and solar energy. Therefore, in these areas, priority can be given to the development of micro-grids for clean energy power generation, making full use of renewable energy sources such as wind energy and solar energy to achieve self-sufficiency. However, wind energy and solar energy depend on natural conditions and have obvious randomness and volatility. Therefore, it is necessary to determine the control strategy of this island-operated microgrid and ensure its economic efficiency. This paper takes wind / solar /diesel engine/ storage island operation microgrid as an example to study the optimal control strategy of this microgrid in island mode, and uses an improved particle swarm optimization algorithm to optimize. The results show that the operation results can meet the needs of users. Both economical.
