Multi-agent coordinated scheduling method for microgrid containing renewable energy sources

Abstract

The invention relates to a multi-agent coordinated scheduling method for a microgrid containing renewable energy sources. The method comprises the steps of S1, constructing a microgrid and main network tie line reliability model; S2, setting a penalty mechanism based on the power supply reliability in the microgrid, and constructing cost benefit models and operation constraint conditions of a conventional unit investor, an energy storage facility investor and a renewable energy investor according to the penalty mechanism of the power supply reliability in the microgrid; S3, setting an objective function, and constructing a multi-agent Nash equilibrium game model; S4, acquiring a Nash equilibrium point of each agent according to a Nash equilibrium game theory and a reinforcement learning theory; and S5, dividing the learning tasks into source tasks and new tasks, and accelerating the learning process of different scenes by utilizing transfer learning to obtain an optimal scheduling matrix. According to the invention, the power supply reliability of the microgrid is effectively improved.

Description

technical field [0001] The invention relates to the field of micro-grids, in particular to a method for multi-agent coordination and scheduling of micro-grids containing renewable energy. Background technique [0002] Renewable energy generation has increased substantially in recent years with increasing environmental pressure and energy demand. However, in the microgrid containing renewable energy, the output of renewable energy units has great uncertainty. In order to ensure the reliability of power supply in the microgrid, it often depends on the connection line between the microgrid and the main grid. Therefore, the reliability of the connection line The impact on microgrid scheduling cannot be ignored. At present, the centralized control method is mainly used for microgrid dispatch control, but the centralized control method is difficult to guarantee the control effect of the multi-energy and big data microgrid today, and the conventional units, energy storage faciliti...

However, in the microgrid containing renewable energy, the output of renewable energy units has great uncertainty. In order to ensure the reliability of power supply in the microgrid, it often depends on the connection line between the microgrid and the main grid. Therefore, the reliability of the connection line The impact on microgrid dispatching cannot be ignored

At present, the centralized control method is mainly used for microgrid dispatch control, but the centralized control method is difficult to guarantee the control effect of the multi-energy and big data microgrid today, and the conventional units, energy storage facilities and renewable energy units of the microgrid There are different investors with different interest demands. The traditional centralized optimization scheduling method cannot present different demands, and it is difficult to mobilize the enthusiasm of all parties to respond to scheduling.
