On-line optimization of micro-grid based on deep reinforcement learning
摘要
Abstract
In view of the micro-grid random optimization scheduling problem,this paper proposes an online optimization algorithm of micro-grid based on deep reinforcement learning.The deep neural network is used to approximate the state-action value function,and the action of the battery is discretized as the output of the neural network.And then,the non-linear programming is used to solve the remaining decision variables and calculate the immediate return,and obtain the optimal strategy through the Q-learning algorithm.In order to make the neural network adapt to the randomness of wind,photovoltaic and load power,according to the wind,photovoltaic and load power prediction curves and their prediction er-rors,Monte Carlo sampling is used to generate multiple sets of training curves to train the neural network.After the train-ing is completed,the weights are saved.According to the real-time input status of the micro-grid,the neural network can output the actions of the battery in real time so as to realize the online optimal dispatching of the micro-grid.Compared with day-ahead optimization results under different fluctuations of wind power,photovoltaic and load power,the effective-ness and superiority of this algorithm in online optimization of micro-grid are verified.关键词
