Embodiment 1
[0075] Aiming at the characteristics that the microgrid system is faced with the random fluctuation and intermittency of renewable energy, and the load demand is difficult to predict accurately, the embodiment of the present invention provides a microgrid energy storage scheduling method based on deep reinforcement learning. The energy storage system agent passes Interact with the environment to obtain reward feedback to obtain the energy scheduling strategy of the energy storage system, including the following steps:
[0076] Step (1): Establish a corresponding simulation model based on the controlled new energy microgrid, specifically including the following sub-steps:
[0077] (1.1) Establish an energy storage system model: use a dynamic model to represent the energy storage system, P b (t) represents the charging or discharging power of energy storage at each time t, and the state of charge of the energy storage battery is represented by SOC(t), then the SOC dynamic model ...
Embodiment 2
[0127] Energy storage system agent building module: according to the simulation model of the controlled new energy microgrid, the microgrid energy storage scheduling is converted into a Markov decision problem, so as to establish the energy storage system agent;
[0128] Energy storage system agent training module: Train the energy storage system agent according to the forecast data of the microgrid. During the training, after the reward obtained by the energy storage system agent from the environment reaches a stable level, save the network parameters and the training ends;
[0129]Energy storage system scheduling module: use the trained energy storage system agent for the scheduling of the energy storage system in the microgrid. At each energy scheduling time in hours, the energy storage system performs the task according to the real-time power generation and load demand of the microgrid. Charge and discharge control.
